摘要：

A 8 x 2nm polarisation independent InP-based demultiplexer operating at similar to 1.54 mu m with a low birefringence wide input waveguide has been produced by incorporating polarisation dispersion compensation into a highly birefringent waveguide. Mode converters were used in each arm of the grating to avoid transition losses. The fibre-waveguide insertion loss is 0.5dB and, misalignment tolerance (at -1dB) is 2.5 mu m. Crosstalk is as low as -30 dB.
