Abstract

Silicon waveguides have, to date, largely been designed to operate near the telecommunication bands in the near infrared. The mid-infrared (MIR) wavelengths, which range from two to twenty microns, are critical for a number of application areas, including chemical bond spectroscopy and thermal imaging. We show results, using commercially available silicon-on-sapphire wafers, for low-loss (4.0 dB/cm) waveguides and what we believe to be the first working microresonators operating at wavelengths around 5.5 um in silicon guides with Q-values as high as 3.0 k. This talk will discuss the applications for mid-infrared integrated photonics in the silicon system, particularly for sensing and nonlinear optics.
