EnglishThe 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. (C) 2007 Elsevier B.V. All rights reserved.
