Title: QUANTUM CASCADE LASER
Abstract:
The invention relates to a quantum cascade laser (300) comprising a gain region (102) between two optical cladding layers (1041, 1042); the gain region (102) has an electron input into the gain region (102) and an electron output from the gain region (102). The invention is characterized in that the laser comprises a hole blocking region (304) at the electron output end.
