A Miniature Integrated Optical Beam Splitter in A1GaAs/GaAs Ridge Waveguides
19 January 1987
In optical integrated circuits for communication and optical signal processing applications, it is desirable to have beam splitters or directional couplers in semiconductors to combine or split the optical signal. The two common approaches for implementing this are by the use of dual-channel waveguide couplers and by the use of Y-couplers.
