Abstract
Signal modulations and coherent signal detections are important for both communications and remote sensing applications. Photonic integration reduces size, weight, cost, and improves the performance of these systems as demonstrated by integrated DFB-laser modulators, receivers and transceivers at near-IR wavelength regions. However, due to the difficulties of waveguide coupling, photonic integration in the mid-IR wavelength range is under-developed. We developed a technique that can monitor mid-IR coupling based on the negative photoconductivity in quantum cascaded (QC) materials that can simplify and optimize laser waveguide coupling in the mid-IR wavelength range.
