Abstract
An array waveguide grating structure includes an input MMI that receives an input optical signal and splits the optical signal into a plurality of signals, each having a defined wavelength. A plurality of input arrayed waveguide structures receive the plurality of signals such that each of the waveguide structures receives one of the plurality of signals. The input MMI, the plurality of arrayed waveguide structures, and the output waveguide are configured using HIC optics.
