Programmable Silicon Photonic Integrated Circuits [PDF]

2020 IEEE Photonics Conference (IPC), 2020
Programmable photonic circuits offer a new way to explore photonic chips: instead of hardwiring waveguide connections, one programs a mesh of tunable couplers. This requires electronics and software routines to govern the behavior of the chip, making it possible to rapidly develop new photonic applications.
