Continuous wave operation of injectorless quantum cascade lasers at low temperatures
Simeon Katz, Andrea Friedrich, Gerhard Boehm, and Markus-Christian Amann
A continuous wave operating quantum-cascade-laser without injector is presented. The core design was taken from a low-threshold pulsed staircase laser. The active zone of one sample was optimized for low threshold current densities, using 60 periods and a low doping of 2.4 x 10 cm/period. The secon ... [Appl. Phys.
