Integrated III-V devices for dual-comb spectroscopy in the mid-infrared
Quantum walk combs have recently been found to be a robust method to obtain coherent and broadband mid-infrared (mid-IR) combs based on semiconductor and compact Quantum Cascade Lasers (QCL). Together with the unique absorption characteristics of the mid-IR, this approach has great potential for spectroscopic sensing applications, among others. In addition, this approach can benefit from the remarkably low, broadband propagation losses of buried InGaAs/InP waveguides, and its homogeneous integration capability with QCLs.
