Integrated gratings for novel photonic integrated circuits [PDF]

2017 Conference on Lasers and Electro-Optics Pacific Rim (CLEO-PR), 2017
Optical Bragg gratings are finding new applications in high frequency pulse generation and in multiple wavelength systems where great precision is required. Sampled Bragg gratings (SBGs) offer great design flexibility. Incorporating sampled grating reflectors in mode-locked semiconductor lasers allows stable pulse streams to be generated at THz ...

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.
