Wavelength Stabilized External Cavity Quantum Cascade Lasers using Cavity Resonator Integrated Grating Filters
Résumé
External cavity diode lasers (ECDLs) are a standard way of building single-mode and narrow-linewidth sources [1], while keeping the intrinsic benefits of semiconductor lasers like compactness, low-cost and high-modulation capability. Traditional ECDLs design uses a bulk diffraction grating in Littrow or Littman/Metcalf configurations. In this paper, we report on the use of recently demonstrated MIR Cavity Resonator Integrated Grating Filters (MIR-CRIGFs) [2] to implement an alternative configuration using a compact and stable cat's-eye configuration.
