Photonic integrated circuits for life sciences
, 2021 A large number of discrete optical components could be replaced by a photonic integrated circuit in a multi-color laser engine for the visible spectral range. The photonic integrated circuit is based on silicon nitride waveguide technology. We report on the use of silicon nitride (SiN) photonic integrated circuits (PICs) in high-value instrumentation ...

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 ...
