Ultralow-VπL Silicon Electro-Optic Directional Coupler Switch with a Liquid Crystal Cladding
Li-Yuan Chiang, Chun-Ta Wang, Steve Pappert +1
An ultralow-VπL photonic switch device is demonstrated utilizing the high optical and electrical field confinement in silicon slot waveguides coupled with the strong electro-optic…
Efficient thermo-optic micro-ring phase shifter made of PECVD silicon-rich amorphous silicon carbide
Li-Yang Sunny Chang, Steve Pappert, Paul K. L. Yu
In this work, the thermo-optic coefficient (TOC) of the silicon-rich amorphous silicon carbide (a-SiC) thin film deposited by plasma-enhanced chemical vapor deposition is character…
Efficient and compact thermo-optic phase shifter in silicon-rich silicon nitride
Hani Nejadriahi, Steve Pappert, Yeshaiahu Fainman +1
The design, fabrication, and characterization of low loss ultra-compact bends in high index (n = 3.1 at λ = 1550 nm) PECVD silicon rich silicon nitride (SRN) is demonstrated and ut…
Thermo-Optic Properties of Silicon-Rich Silicon Nitride for On-chip Applications
Hani Nejadriahi, Alex Friedman, Rajat Sharma +3
We demonstrate the thermo-optic properties of silicon-rich silicon nitride (SRN) films deposited using plasma-enhanced chemical vapor deposition (PECVD). Shifts in the spectral res…
