阈值前后的FWHM从4.7nm窄化到3.2nm。

Abstract

Organic microcavity structures were designed and fabricated with distributed Bragg reflector as the mirror and Alq:DCJTI host-guest doping system as the gain medium. The standing wave field within microcavity was simulated by using the transfer matrix method

and a suitable microcavity structure was determined. The lasing properties of the microcavity laser were studied by a UV pulse laser. The output wavelength of the microcavity laser is 650 nm. An obvious lasing behavior was observed with a threshold intensity of 110Wcm

. FWHM was narrowed from 4.7 to 3.2nm before and after the threshold.
