Questions regarding photonic integrated chip design
As I plan my next few semesters, I’ve been thinking carefully about which classes to take. I’m particularly intrigued by chip design and its applications in quantum computing, and I see enormous potential in Photonic Integrated Circuits (PICs) for quantum sensing, communication, and computing. At my university, there are several relevant course options. On the electronics side, there are digital VLSI design courses, as well as analog circuit courses that progress into monolithic amplifier design and microwave circuits. On the photonics side, there are classes on waveguides, antennas, and light propagation, along with laser courses that use tools like COMSOL and Lumerical (which I know are often applied to PICs). However, there aren’t any courses specifically focused on PICs. Since I can’t take everything, I’m trying to figure out which classes will best prepare me to work with PICs in the future. A key part of this decision seems to hinge on whether PICs for quantum applications should be thought of more as analog devices, digital devices, or something in between.
