Quantum Cascade Lasers,nce band optical transition to generate the laser emission. As a result, the threshold power density in the interband cascade laser is lower by an order of magnitude compared to the quantum cascade laser.

Electrons, have a wide range of kinetic energies, depending on its velocity. It can be accelerated, in which case it also radiates photons. Electrons can interact with matter through mechanical impact or electro-magnetic influence. Only twenty-seven years separate the discovery of the electron as a particle c

Photons, photon is the unit intensity of the electro-magnetic field. Once created, a photon is characterized by its energy . which remains unchanged until the photon is destroyed. Maxwell’s equations describe the electromagnetic fields in the classical regime, including propagation of photon beams as a func
