Integrated phase-locked lasers and photonic integrated circuits for remote gas sensing

An indium phosphide photonic integrated circuit for integrated path differential absorption lidar remote gas sensing was developed. Phase locking of the two integrated lasers and measurement of a carbon dioxide absorption line centered at 1572.335 nm was demonstrated.
