Abstract :
Summary form only given. We propose an optical tunable filter for wavelength division multiplexing (WDM) applications. The filter consists of a classical fan Solc stack placed in a ring cavity, with the polarizer outside and the analyzer inside it. Each birefringent plate is formed with the nematic-phase liquid crystal and is associated with a compensation birefringent plate, which introduces a constant phase retardation between the two eigen axes.
