ROLE OF TWO-PHOTON ELECTRONIC TRANSITIONS IN OPERATION OF QUANTUM CASCADE LASERS

Abstract

The theory of dynamic conductivity of three-barrier resonant tunneling structure in weak electromagnetic field taking into account two-photon electronic transitions with different frequencies is developed within the approximation of effective mass and rectangular potential wells and barriers for the electron using the analytically obtained solutions of complete Schrodinger equation. It is shown that the contribution of two-photon electronic transitions into the total magnitude of dynamic conductivity for some configurations of resonant tunneling structure can approach 40% for the transitions with radiation of electromagnetic wave.
