Arrayed waveguide grating optical multiplexer/demultiplexer

摘要

An arrayed waveguide grating optical multiplexer/demultiplexer includes an arrayed waveguide connected to at least one first optical waveguide via a first slab waveguide. A plurality of second optical waveguides are connected to the arrayed waveguide via the second slab waveguide. A number (Nch) of the plurality of second optical waveguides is determined to substantially satisfy the equation, DELTAffsr=DELTAfch.Nch.DELTAffsr is Free Spectral Range of the arrayed waveguide grating optical multiplexer/demultiplexer. DELTAfch is a frequency interval between frequencies of lights to be input to the arrayed waveguide grating optical multiplexer/demultiplexer for being multiplexed or lights to be output from the arrayed waveguide grating optical multiplexer/demultiplexer after being demultiplexed.
