A hybrid laser with an optical negative feedback circuit integrated on a silicon photonics chip was investigated. Our numerical analysis verified that the laser can function as a wavelength-tunable laser with a spectral linewidth of less than 10 kHz. The result was supported by experiments.

Integrated silicon photonics in the visible range is one of the areas that is emerging and growing in the market for different applications, such as: biosensing, optogenetics, quantum computing, imaging and display, fluorescence microscopy, cytometry, tomography, LIDAR and Lifi. Here, we present the first steps to build a process design kit of components in the visible range centered at 633 nm using a LPCVD silicon nitride platform. The first basic elements are presented (grating couplers, single mode waveguides and a MMI).

A 1D photonic crystal waveguide supporting two propagating modes is proposed for the creation of a bimodal interferometer. By properly designing the structure, slow wave behavior can be used to significantly improve the performance and reduce the footprint of the device.

Multidimensional Optimization of Devices via Adiabatic Loss Limiting (MODALL) is used to optimize the profile of both a taper (1D problem) and an interlayer transition (2D problem). Both devices are compared to their nominal linear counterparts through simulation and measurement confirming a significant improvement in transmission across the O-band.

We demonstrate a precise in-situ loss measurement technique using in-line silicon photodetectors. By measuring the photocurrents from silicon photodetectors embedded in a silicon waveguide, we extracted the waveguide loss with a standard deviation of 0.03 dB/cm based on 100 repeated measurements.

We report low-temperature (<400˚C) SiN waveguides with lowest propagation losses demonstrated so far for BEOL compatible processes, using a physical vapor deposition technique. Propagation losses as low as 0.2 dB/cm and of 0.43 dB/cm are achieved for single-mode waveguides across the C- and O-band, respectively.
