The transfer of optical power between a fibre, side polished close to the core, and a multimode waveguide overlay is periodic in terms of variation of the input wavelength as individual high order overlay modes are tuned in and out of resonance with the fibre mode. The development and characterisation of such devices using polished glass, lithium niobate, and vacuum deposited overlays are reported here. It is concluded that this technology is capable of yielding rugged channel selection filters and wavelength division demultiplexers with losses of less than 0.2dB and wavelength selectivity down to a few nanometres.
