Spot size converter (SSC) plays a role of paramount importance in the silicon photonics
integrated circuit. In this article, we report the design of a reconfigurable spot size converter …

We present a C-band grating coupler for the 800 nm silicon nitride platform with fully etched
grates and suppressed back-reflection. By interrupting the first few grates in the center of the …

The interlayer waveguide grating coupling efficiencies under angular (rotational)
misalignments are simulated using the 3D rigorous coupled-wave analysis (3D-RCWA) …

We describe a resonantly enhanced Mach-Zehnder modulator (MZM) that can be operated
over a wide temperature range of 55° C without being actively biased, while providing a …

We investigate the effect of tunable filtered optical feedback on a commercial DFB laser
edge coupled to a silicon photonic planar integrated circuit in which a tunable reflector has …
