摘要

We investigate the amplified spontaneous emission (ASE) from an Ag-backed poly[2-methoxy-5-(2'-ethylhexyloxy)1,4-phenylenevinylene] (MEH-PPV) film with different film thicknesses.The ASE characteristics of Ag-backed MEHPPV films with different thicknesses show that increasing the film thickness can reduce the influence of the Ag cladding.The threshold,the gain,and the loss of the device with a thickness of 170 nm are comparable to those of a metal-free device.The lasing threshold of this device is about 7.5...
