Patent ID: 7466883

Claim:
An optical filter comprising: an input waveguide; a first subfilter containing a first microsphere, said first subfilter being fixed proximate to said input waveguide; a second subfilter containing a second microsphere, said second subfilter which is fixed proximate to said first subfilter; an output waveguide fixed proximate to said second subfilter; a resonate structure-waveguide interface formed in an area of reduced cladding of said input waveguide and said output waveguide; a direct subfilter interface, which places said first microsphere and said second microsphere in contact with one another; wherein said first microsphere resonates in WGM for a first group of resonate signals, and said second microsphere resonates in WGM for a second group of resonate signals, such that said first subfilter and said second subfilter have a resonate signal in common among said first group and second group of resonate signals; and wherein due to said resonate signal in common, a light signal from said input waveguide to said first microsphere and said second microsphere, is passed to said output waveguide; and an electronic gate which provides on/off control by one of two WGM controls; wherein polarization is applied to one of said first microsphere and said second microsphere to produce a linear electro-optic effect to accomplish said electronic control.
