Abstract:
An optical wave power control device for varying the transmitted power at at least one optical frequency (i.e. optical carrier wave) on an optical wave power transmission member, comprising:an optical wave transmission member configured with a length of small cross-section for propagating optical power at at least one optical frequency in a spatial mode partially extending outside the cross-sectional periphery of the member; at least one whispering gallery mode optical wave resonator disposed in coupling relation to the spatial mode of the wave transmission member, and positioned to exchange wave power between the spatial mode and a spatial mode of the resonator, and at least one control means, each in operative relationship to a different one of the at least one resonators, for varying round trip loss, &agr;, of at least one of the resonators relative to a critical coupling condition in the overcoupled regime.
