AbstractThe mid-infrared (IR) wavelength region (2–20 µm) is of great interest for a number of applications, including trace gas sensing, thermal imaging, and free-space communications. Recently, there has been significant progress in developing a mid-IR photonics platform in Si, which is highly transparent in the mid-IR, due to the ease of fabrication and CMOS compatibility provided by the Si platform. Here, we discuss our group’s recent contributions to the field of silicon-based mid-IR photonics, including photonic crystal cavities in a Si membrane platform and grating-coupled high-quality factor ring resonators in a silicon-on-sapphire (SOS) platform. Since experimental characterization of microphotonic devices is especially challenging at the mid-IR, we also review our mid-IR characterization techniques in some detail. Additionally, pre- and post-processing techniques for improving device performance, such as resist reflow, Piranha clean/HF dip cycling, and annealing are discussed.

We designed High-Q micro-ring resonators based on SOI material. A new method of using a top SiO2 layer to cover the waveguide is applied and the tested Q factor is as high as 1.0135×104. Micro-ring resonator has been fabricated using Electron-Beam Lithography and Inductive Coupled Plasma. OptiFDTD was used to simulate the micro-ring resonator and we compared the transmission spectrum of this resonator with the resonator without SiO2 covering.
