Abstract
A 8×2 nm polarisation independent InP-based demultiplexer operating at ~1.54 μm 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 0.5 dB and, misalignment tolerance (at -1 dB) is 2.5 μm. Crosstalk is as low as -30 dB
