Paper Abstract

A polarization maintaining single mode fiber birefringent filter which could function as a two channel, three port wavelength selective multiplexer/demultiplexer has been designed, constructed, characterized, and evaluated. A highly accurate and novel procedure was used to measure the wavelength dependence of the beat length of the AT&T rectangular PM fiber used in the prototype filter. In addition, a computer simulation of birefringent filters (based on a new first principle theory of polarized signals in birefringent media) was used as a design tool and found to be in excellent agreement with the spectral response of the prototype filter. The free spectral range of the prototype filter is 326 nm with pass/stop bands of 36 nm and 45 nm about the 1373.2 nm and 1533.3 nm wavelengths, respectively. The insertion loss, which was not optimized, was 4.3 dB. The crosstalk was -11.3 dB and -24.2 dB for the parallel and crossed orientations of the polarizers.
