The realisation and performance of an all-passive silicon-based 4*4 planar optical hybrid receiver for operation at 1.55- mu m wavelength is reported here for the first time. Measurements show 5 degrees /12 degrees /12 degrees /9 degrees output phase deviations, without tuning or trimming. Network dimensions are 270*1200 mu m. This is the most compact 4*4 planar optical hybrid reported so far, demonstrating the convenience and feasibility of all-passive phase diversity operation
