✦ Synopsis

The strong coupling of bound-to-quasi-bound intersubband transitions with the confined mode of a semiconductor microcavity, resulting in the formation of intersubband polaritons, has been observed. The quasi-bound state above the barrier is formed by growing electron Bragg mirrors on both sides of the quantum well. With the application of an electric field, the oscillator strength of the transition is redistributed between the quasi-bound state and the above-barrier miniband formed by the Bragg superlattice, which deteriorates the intersubband absorption intensity, leading to a decrease in the intersubband polariton coupling. The paper reports the preliminary results in the quantum interference control of intersubband polariton coupling.

A theoretical description of the interaction between confined excitons and photonic modes in pillar microcavities is given. For quantum-well excitons in the strong coupling regime, the Rabi splitting is reduced compared to the reference planar cavity and a radiative splitting of exciton states coupl
