  • Planar waveguide diffractive beam splitter/coupler
    Patent number: 6621959
    Abstract: The invention provides a planar waveguide diffractive 1×N beam splitter/coupler. It utilizes an integrated circuit fabrication process to fabricate an integrated optic. A Fourier transform diffractive optical element (DOE) is formed on one end of a planar waveguide (planar lightwave circuit; PLC). Thus, an incident beam coming from one end of the planar waveguide can be diffracted into a plurality of output beams. On the other hand, a plurality of incident beams coming from one end of the planar waveguide can be coupled into one output beam. The beam splitter/coupler is easy to fabricate, small in size and more flexible for applications.
