Method and apparatus for channel selective control of light propagation in an optical waveguide |
摘要 |
A variable optical device for selectively controlling propagation of light within an optical waveguide. The optical device comprises: a relief modulation defining a grating disposed proximal the waveguide and having a respective grating index of refraction nG; a matrix surrounding at least the relief modulation, the matrix having an index of refraction nEO that is controllable, in response to a selected stimulus between a first value that is substantially equal to the grating index of refraction nG, and a second value that is different from nG; and at least one electrode for supplying the selected stimulus to the matrix-grating system.
