Paper 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 400-500 nm high silicon waveguides can have propagation losses as low as ~ 4 dB/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 3-4 μm region and that low loss mid-infrared passive devices can be realized on it.
