“…From the theoretical point of view we may refer to a number of published papers in this subject, including the earliest papers published by Peters and Allen, [1,2] Casperson and Yariv, [3] Casperson, [4] and Pert. [5] In recent years, on the other hand, with the emerging need of laser materials for their vast applications in laser technology, conjugated polymer films, BuEH-PPV, [6] MEH-PPV, [7][8][9] cyano substituted oligo (CN-DPDSB) single crystal, [10] InAs quantum dots, [11] etc., were studied extensively, where due to their importance, the subject has also been reviewed. [12,13] The most important interest in these studies is to use ASE as a source of coherent radiation.…”

Amplified spontaneous emission (ASE), including intensity and bandwidth, in a typical example of BuEH-PPV is calculated. For this purpose, the intensity rate equation is used to explain the reported experimental measurements of a BuEH-PPV sample pumped at different pump intensities from Ip = 0.61 MW/cm2 to 5.2 MW/cm2. Both homogeneously and inhomogeneously broadened transition lines along with a model based on the geometrically dependent gain coefficient (GDGC) are examined and it is confirmed that for the reported measurements the homogeneously broadened line is responsible for the light–matter interaction. The calculation explains the frequency spectrum of the ASE output intensity extracted from the sample at different pump intensities, unsaturated and saturated gain coefficients, and ASE bandwidth reduction along the propagation direction. Both analytical and numerical calculations for verifying the GDGC model are presented in this paper. Although the introduced model has shown its potential for explaining the ASE behavior in a specific sample it can be universally used for the ASE study in different active media.

We investigate the effect of a metallic electrode on the ability for poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylene vinylene] (MEH-PPV) film to undergo amplified spontaneous emission (ASE). The threshold of the device with Ag cladding is about 10 times greater than that of a metal-free device, but metal such as Al completely shuts off ASE. The ASE recurs when a thin spacer layer, such as a few nanometers of SiO2, is introduced between the MEH-PPV film and the Al cladding. Compared with the Cu or Al electrode, the Ag cladding is most suited to serve as an electrode with its low optical loss due to its high work-function and reflectivity.
