Light is as fascinating as it is mysterious and at the same time an important basis of life for many animals and plants. Without light, there would be no photosynthesis, it influences your mood and is essential for the body's own production of vitamin D. But light can do even more, it is pure energy that can be used to read, cut and transmit data at lightning speed. In manufacturing or medicine, the applications of light are potentially endless, but it takes clever and creative minds to develop the appropriate technologies to harness light in the ways mentioned.

The Bachelor's degree programme "Optical Technologies: Lasers and Photonics" represents a unique offering at a German university in its form. There are only a few universities that offer a Bachelor's degree in optics and photonics. If you want to take up a degree programme that combines different scientific branches beyond rigid disciplinary boundaries, then study optical technologies and equip yourself in a versatile way for a career in one of the key technologies of the 21st century.

Prepare yourself for an exciting course of study that will teach you a combination of physical, mathematical and chemical fundamentals with typical engineering problem-solving skills. After graduation, you will have a broad knowledge of optical technologies. Optical technologies are used to generate, form, transmit and utilise light and are used, for example, in measurement technology, material processing or data storage.

  • Semester 1 - 3

    The beginning of your studies focuses mainly on teaching the basics of mathematics and engineering. These are basic skills in physics, mathematics, technical mechanics, construction theory and electrical engineering and information technology. These subjects are represented by extensive compulsory modules up to your third semester. The field of optics, on the other hand, builds up steadily over the semesters with increasing scope.

    You start with a general overview of the basics of optics and radiation optics. Wave optics is covered in the second semester, followed by beam sources and lasers in the third semester. Mathematical models and methods will be integrated into wave and radiation optics in the first two semesters. From the third semester onwards, the basics of general chemistry are also offered as a compulsory module as preparation for working with optical materials.

    A special feature of your studies is the practice-oriented Bachelor project, which is also implemented in the first semester. In the bachelor project, you work in a group with fellow students to find an engineering solution to a current research or practical problem. Several institutes of the Faculty of Mechanical Engineering provide tasks, such as the development of an additional lens for a smartphone, the construction of an electrically driven car or creating new valuable materials from recycled plastic. In the Bachelor project, you already gain practical experience in the first semester, develop targeted solutions and implement them directly.

    Fundamentally, your studies are made up of lectures, exercises, seminars, laboratories, excursions and tutorials. The latter teaches you key skills such as scientific work or communication and organisation techniques.

  • Semester 4 - 5

    The competences taught up to the fourth semester and the basic knowledge taught from the various scientific disciplines are interwoven in the fourth and fifth semesters into mostly new modules and supplemented by two lectures on quantum technologies. In addition, a compulsory elective area opens up for you from the fourth semester onwards, consisting of two compulsory elective modules. The compulsory elective modules form the foundation for an initial individual specialisation.

    In order to design engineering methods and strategies in the planning, construction, design, production, commissioning, testing and evaluation of technical products and process chains and to transfer the engineering fundamentals trained in the first three semesters into in-depth systemic thinking, the compulsory module optics production is also created in the fourth semester and deepened with a view to optics construction. Lighting technology is added as a profile-forming module in the degree programme and functions as a bridge between engineering fundamentals and the application of optics in the fields of engineering activity.

  • Semester 6

    In the sixth semester, you can complete a twelve-week industrial/research internship, but you do not have to. If you decide not to do the internship, it will be included in the subsequent Master's programme and you will have to take other elective modules as a substitute. The option to place the specialised internship in the consecutive Master's programme does have some advantages.

    On the one hand, it can prevent an extension of the study time in cases where there are difficulties in finding a placement. On the other hand, you may not know which specialisation best suits your individual interests until you have completed in-depth modules in the Master's programme and can thus better select a suitable internship.

    In addition to the specialised internship (or alternatively the elective modules), you will also write your Bachelor's thesis in the sixth semester, which you will present in a lecture afterwards. If everything goes as planned and the exams are successful, you will receive the academic degree "Bachelor of Science", which is not only your first professional qualification, but also qualifies you to take up a further Master's programme.

Preliminary internship

For the Bachelor's degree programme in Optical Technologies: Lasers and Photonics, you have to complete a so-called pre-study internship of eight weeks in total. Ideally, you should have done this before you start your studies in order to gain a basic understanding of the course content and to avoid time constraints later on. But if not, that's no problem, you can also complete the pre-study internship during the semester break. It must be successfully completed by the fifth semester. The areas of activity to be covered are specified in the internship regulations.

As a prospective engineer, it is important to gain experience in industry and to get to know basic operational processes. Small and medium-sized companies in the Hannover Region are suitable for a preliminary internship. The Internship Office of the Faculty of Mechanical Engineering will be happy to help you with any questions you may have.

Specialist internship

In contrast to the pre-study internship, the specialised internship is not aimed at first-year students, but at graduates who are about to graduate. It serves the purpose of acquiring experience in typical fields of work and areas of activity in professional practice.

Accordingly, the twelve-week specialised internship is characterised by the integration of the interns into a working environment of persons in an engineering occupation or corresponding qualification with a predominantly developing, planning or directing activity character. The best place for an internship is one in which you are integrated into the typical day-to-day business of the company to the greatest possible extent and in an actively contributing manner. As with the pre-study internship, the internship office is your first point of contact if you have any questions.

As a graduate of the Bachelor's degree programme "Optical Technologies: Lasers and Photonics", you are ideally prepared to work in the laser and optics industry. Since the degree programme deliberately avoids a specific specialisation, you can consider yourself a fundamental specialist in optical technologies because you have an interdisciplinary and broadly diversified knowledge. Fields of application for optical technologies can be found in medical technology, for example in laser eye surgeries, in the automotive, aerospace and entertainment industries and in information technology. As an alternative to your profession, you can also study for a Master's degree with an optional doctorate.

Hanover offers particularly favourable conditions for the degree programme Optical Technologies: Lasers and Photonics, not only because particularly close cooperation between the basic disciplines can be achieved here, but also because the Laser Zentrum Hannover e. V. (LZH) is a direct interface to industry. (LZH), there is a direct interface to industry, so that companies can be well integrated into ongoing research and teaching and you, as a student, can be introduced to industry more easily.

In addition, Leibniz University has been successfully offering a Master's programme in Optical Technologies for more than ten years, which is excellently suited for deepening the content acquired in the Bachelor's programme. In addition to the German- and English-language Master's programme in Optical Technologies, you also have direct access to the new Master's programme in Quantum Engineering as a graduate of the Bachelor's programme. You can gain comprehensive insights into research at the Hannover Centre for Optical Technologies (HOT).

The recently founded Leibniz School of Optics & Photonics (LSO) is another institution that suggests that Hannover is an advantageous location within the national and international research landscape. This is also supported by the PhoenixD cluster of excellence, which includes more than 100 scientists conducting joint research in the field of optics and photonics.
