Abstract

We investigate spectral peculiarities of multilayer system, consisting of two identical CLC layers and a Rhodamine 6G doped polymethyl metacrylate thin film sandwiched between them. We measure transmission and reflection spectra of the system. A small mismatch between Selective reflection band and corresponding dip in transmission spectrum is observed. Also we investigate luminescence spectrum of this system at pulsed and CW mode pumping at various temperatures. The results show that maximal intensity of luminescence spectrum at constant pumping power is observed at 18°C and the weakest luminescence is observed at 20°C, the luminescence spectra at higher and lower temperatures are “confined” between these two spectral curves.
