Student working on a research project.

Free-Space Optical Communications

The goal of the project is to design, build and test a free-space optical communication link by using commercially available IR laser diodes. Various modulation schemes will be implemented based on IR laser diodes. Each modulation and demodulation method will be tested for spectral efficiency, power efficiency, and receiver detection error rate. Light intensity, power consumption, and data transmission integrity will be measured and compared for different modulation schemes. An additional goal of the project is to design novel high-performance modulation scheme for free-space optical communications.
