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.

In this study, a leaf-like [Formula: see text] mixed phase nanosheets array was successfully prepared by anodization. XRD, EDS, and XPS analysis confirmed the formation of [Formula: see text] mixed phase nanostructures. SEM images indicate that the fabricated [Formula: see text] mixed phase nanosheets almost grow vertically on the substrate. The average height of nanosheets is approximately 500 nm. The optical absorption of the mixed phase covers the entire wavelength region of visible light and a little part of the near-infrared region of short wavelength.
