Abstract
Abstract Principles and experimental examples of controlling spontaneous emission and laser oscillation using optical microcavities are presented. Particular attention is paid to one-dimensional optical confinement structures with pairs of planar reflectors (planar microcavities). A simple analysis shows that a large coupling of spontaneous emission into the cavity mode causes the significant changes in the threshold behavior of the laser oscillation. Differences between the spontaneous and the stimulated emission dominant regimes are discussed. The ultrafast response capability of a microcavity laser is also shown. These laser oscillation properties are experimentally examined employing microcavities containing an organic dye solution.
