Curved waveguide grating demultiplexer (CWG) with a flattened response via bimodal output waveguides [PDF]
, 2022 We demonstrate a compact wavelength demultiplexer for the silicon-on-insulator platform based on the curved waveguide grating (CWG) architecture. The proposed device uses bi- modal output waveguides to achieve a low-loss flattened spectral response.

Optical Frequency Combs in External Cavity SiN Hybrid Lasers [PDF]
We analyze the emergence of optical frequency combs in a III-V SiN hybrid laser. Our model accounts for the narrow band effective mirror reflectivity and allows to simulate laser dynamics as a function of the bias current and the detuning of the lasing ...

Programmable non-volatile spectral shaping in PCM-enhanced grating-assisted couplers [PDF]
We present a novel bandwidth programmable photonic integrated filter enabled by Phase-Change Materials (PCM). PCMs are used to enhance and unlock dynamic and non-volatile spectral shaping in Grating-assisted Contra-Directional Couplers (GACDC). Through

Frequency combs in III-V/SiN integrated hybrid lasers with narrowband mirror [PDF]
We address the dynamics of a III-V/SiN external cavity hybrid laser with a frequency-selective mirror. Simulations through a set of time-delayed algebraic equations accounting for the narrowband SiN mirror reflectivity demonstrate that CW instability ...
