ABSTRACT:
An optical device, such as for example a wavelength division multiplexer/demultiplexer, a wavelength router, an optical comb filter or a planar lens, having a first coupler and a second coupler which are connected by an array of optical waveguide channels. At least one of the couplers is a multimode imaging component (MMI), which has the property that the radiation distribution at any input thereof is imaged onto each of the coupler outputs and with uniform power distribution among the outputs. Efficient power transfer in thereby achieved. Phase differences between the inputs and the outputs are compensated by appropriate differences in optical pathlength of neighboring channels in the array.
