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 one-dimensional beam steering with end-fire facet antennas over a wid

We demonstrate the DC-Kerr effect in plasma enhanced chemical vapor deposition (PECVD) silicon-rich nitride (SRN) and use it to demonstrate a third order nonlinear susceptibility, χ ( 3 ) , as high as ( 6 ± 0.58 ) × 10 − 19 m 2 / V 2 . We employ

We demonstrate low loss ultra-compact bends in PECVD silicon rich silicon nitride and utilize them towards realizing efficient thermo-optic MMI switches with Pπ = 23 mW and a footprint of 68 x 68 µm2.

We demonstrate electro-optic switching using the DC-Kerr effects in a bus-coupled integrated photonic racetrack ring resonator made of Silicon-rich Nitride and find its third order nonlinear susceptibility, χ(3), of 6x10-19 m2/v2.

We characterize the thermo-optic coefficient of silicon nitride films with varying silicon contents using plasma-enhanced chemical vapor deposition (PECVD). A clear relation between the silicon content and the exhibited thermo-optic coefficient has b
