Planar lightwave circuit optical splitter/mixer

Abstract:

Planar waveguide junctions are described with a waggled transition section connecting input waveguide sections with output waveguides sections, in which the waggled transitions have alternating segments matching the input waveguide and output waveguides to efficiently transition the optical signal. The planar waveguide junctions can be used to form efficient optical splitters, mixers, or taps.
