Mid-infrared photonics devices in SOI

Mid-infrared photonics devices in SOI
Mid-infrared photonics devices in SOI
In this paper we present silicon photonics devices designed for the 3-4µm wavelength region including waveguides, MMIs, ring resonators and Mach-Zehnder interferometers. The devices are based on silicon on insulator (SOI) platform. We show that 400-500nm high silicon waveguides can have propagation losses as low as ~4dB/cm at 3.8µm. We also demonstrate MMIs with insertion loss of 0.25 dB, high extinction ratio asymmetric Mach-Zehnder interferometers, and SOI ring resonators. This combined with our previous results reported at 3.4µm confirm that SOI is a viable platform for the 3-4µm region and that low loss mid-infrared passive devices can be realized on it. Keywords: Mid-infrared, silicon, silicon-on-insulator, Mach-Zehnder interferometer, multimode interference, ring resonator.

Abstract

In this paper we present silicon photonics devices designed for the 3-4µm wavelength region including waveguides, MMIs, ring resonators and Mach-Zehnder interferometers. The devices are based on silicon on insulator (SOI) platform. We show that 400-500nm high silicon waveguides can have propagation losses as low as ~4dB/cm at 3.8µm. We also demonstrate MMIs with insertion loss of 0.25 dB, high extinction ratio asymmetric Mach-Zehnder interferometers, and SOI ring resonators. This combined with our previous results reported at 3.4µm confirm that SOI is a viable platform for the 3-4µm region and that low loss mid-infrared passive devices can be realized on it. Keywords: Mid-infrared, silicon, silicon-on-insulator, Mach-Zehnder interferometer, multimode interference, ring resonator.
