Abstract
A multi-grading filter with polarisation-independent channel positions and integrated with two amplifiers has been fabricated in InGaAsP/InP. The four tunable Bragg gratings allow the selection of one out of four channels in a WDM system at 1.55 μm. A packaged device with no fibre-to-fibre loss and worst case crosstalk below -16 dB has been fabricated
