Subject
My research topic deals with the interface between electrical and optical communications. Basically, the challenge here is to enable the fastest, most efficient and most accurate conversion of an optical signal into an electrical one and vice versa. Specifically, I am currently researching the use of artificial neural networks for optical data transmission. The aim is to efficiently and quickly compensate disturbances such as noise or nonlinear distortions from the transmission channel. The neural networks will be realized by energy efficient mixed-signal neurons, which potentially require a fraction of the energy of classical, digital neurons for computing operations.
