Abstract

The first broadband polarisation independent Phasar based demultiplexer/filter is demonstrated employing non-birefringent InGaAsP(λg = 0.97 μm)-on-InP raised strip waveguides. The device exhibits a channel spacing of 2 nm, on-chip loss of 4-5 dB, a cross talk better than -25 dB and a 3 dB channel bandwidth of 0.9 nm. The Phasar size is 2.6×2.3 mm2. The fibre-chip-coupling loss is less than 1 dB.
