Coherent beam-combining of quantum cascade amplifier arrays
May 10, 2015
CLEO: Conf. on Lasers and Electro-Optics, 10-15 May 2015.
We present design, packaging and coherent beam combining of quantum cascade amplifier (QCA) arrays, measurements of QCA phase noise, the drive-current-to-optical-phase transfer function, and the small signal gain for QCAs.
