A tunable wavelength-division multiplexer/demultiplexer, based on a polarisation-insensitive birefringent optical filter design, is described. The two channels of the device can each be tuned, with the channel separation adjustable over a wide range. Experiments with 6 to 30 nm laser channel separations have yielded optical crosstalk values of less than −20 dB.
