Abstract
An optical component is disclosed. The optical component includes an input waveguide having an expansion region expanding from an input port to a multimode port. The expansion region is configured to receive a light signal through the input port. An array waveguide grating is configured to receive a light signal from the expansion region of the input waveguide. An output waveguide has an output port configured to receive the light signal from the array waveguide grating. The output port has dimensions that are different from dimensions of the input port. In some instances, a function expressing the expansion from the input port to the multimode port includes an exponential function and/or a sinh function.
