Abstract

The paper presents experimental construction of a liquid-crystalline Bragg filter. The filter is designed as a lowcost WDM decoupler but can also function as demultiplexer in polarisation-coded transmission or may be used as a variable, electrically controllable bandpass filter. Theoretical basis, principle of operation and results of experimental examination of the device are given.
