Gain optimization in electrically pumped AlGaAs quantum cascade lasers
(Optical Soc Amer, Washington, 2002)
The design of the active region of a current-pumped quantum-cascade laser to achieve maximal gain is proposed. Starting with an arbitrary smooth potential, a family of isospectral Hamiltonians with a predefined energy ...
