Methane absorption spectroscopy with a hybrid III-V silicon external cavity laser

View publication


We present line-scanned methane absorption spectroscopy at 1656.5 nm using a multisection hybrid III-V silicon external-cavity laser. The laser demonstrates > 2 nm tunability and single-mode operation with SMSR > 50 dB for high-resolution spectroscopy.
