Spontaneous emission and optical gain in a Fabry–Perot microcavity

The Fabry–Perot microcavity is analyzed in terms of its modification of the spontaneous emission and stimulated emission from a thin gain medium, which is contained between distributed Bragg reflectors. The structures correspond to the vertical‐cavity surface‐emitting semiconductor laser. Gain enhancement due to the cavity is calculated and compared to the case of a large Fabry–Perot cavity. The critical parameters in determining the degree of gain enhancement are the (large cavity) coherence length of the spontaneously emitted wave packet, and reflector design.
