Abstract

An apparatus includes a first coupler formed on a substrate coupled with multiple waveguides spaced apart respectively to channel multiple input lights with different wavelengths. The apparatus further includes a wavelength dispersive device formed on the substrate and configured to diffract the multiple input lights to generate an image of diffracted lights coincident at a spot on a focal line associated with the wavelength dispersive device. The apparatus also includes a second coupler positioned in a proximity outside of the substrate and configured to out-couple a light signal with multiplexed wavelengths directly from the image at the spot of the focal line to an external optical device. The multiplexed wavelengths include all different wavelengths of the multiple input lights. The apparatus may include waveguide tapers to re-image the light focused by the wavelength dispersive device to improve coupling efficiency and tolerance. The apparatus may be operated as a wavelength multiplexer or demultiplexer.
