Advanced Lab Courses

This lab course focuses on the building of a display for a digital clock.The clock is based on a seven-segment display with liquid crystals, polarizers, implemented on glass substrates. All processing steps, including sputtering ITO, spin coating with photo resist and polyimide, photo lithography, wet chemical patterning, and cell assembly are performed by the participants in the clean room at the IGM. Finally, the display is connected to an IC to form a simple alarm clock. The participants can retain the clock they have built.

Information about the lab course:

• The lab course takes place during the first week after the end of lecture period in the summer semester
• Registration until 21^st april 2023 online via ILIAS (please make sure you fill out the poll)
• Participants will be assigned to groups of three
• The lab course itself will take place at the Institute for Large Area Microelectronics.

The lab course Optical Signal Processing takes place in the winter semester during the lecture period. Successful completion of the lecture "Optical Signal Processing" is strongly encouraged. Students will perform experiments on topics including:

• Spatial and temporal coherence
• Collimation (homogenous plane waves)
• Imaging and Refraction
• Diffraction
• Fourier Optics
• Design and production of synthetic holograms
