Simulation of gain in quantum cascade lasers
(2009) Novel In-Plane Semiconductor Lasers VIII 7230. p.72301-72301- Abstract
- The gain profile of a quantum cascade laser is strongly influenced by
the lifetime of the carriers in the upper and lower laser state. The
quantitative description of gain within the concept of nonequilibrium
Green's functions allows for a detailed understanding of various
features affecting the gain spectrum:
Compensation effects between scattering processes in the upper and lower laser
level, reduction of gain due to coherences between nearly degenerate
upper laser states, and dispersive gain without inversion.
