Abstract: An experimental investigation on spontaneous emission properties of Fabry-Perot microcavities consisting of quarter-wavelength ZnS/Cryolite Bragg mirrors and a lithium fluoride (LiF) thin film colored with low-energy electron beam lithography is reported for the first time. Angular-resolved photoluminescence measurements show the modifications of F-2 color centers visible spontaneous emission. The resonator induces a narrowing of the emission spectrum and a related increase in the directionality and intensity of the emission along the cavity axis. (C) 2001 Elsevier Science B.V.
