Realization of a wide steering end-fire facet optical phased array using silicon rich silicon nitride
Hani Nejadriahi, Prabhav Gaur, Karl Johnson +3
The design, fabrication, and characterization of a 16-element optical phased array (OPA) using a high index (n = 3.1) silicon rich silicon nitride (SRN) is demonstrated. We present…
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…
Silicon-organic hybrid thermo-optic switch based on a slot waveguide directional coupler
Li-Yuan Chiang, Chun-Ta Wang, Steve Pappert +1
We propose and demonstrate a passively biased 2 by 2 thermo-optic switch with high power efficiency and fast response time. The device benefits from the highly concentrated optical…
