DIRECTIONAL OPTICAL MODULATION WITHIN AN OPTICAL WAVEGUIDE:
(under the class definition) Subject matter wherein the path of a light wave exiting a waveguide is varied in accordance with a varying signal applied to the waveguide which can be of any energy form.
(1) Note. The directional modulation must take place exclusively within the waveguide. Optical directional modulation occurring outside of a waveguide is classified in Class 359.
(2) Note. This includes elasto-optic directional modulation, wherein deflection of a light wave output from an optical waveguide is varied in synchronization with the amplitude of an impressed mechanical stressing thereof.

1+, for light wave temporal modulation within an optical waveguide wherein the light beam is modulated relative to time in accordance with the modulating input signal.

359, Optics: Systems (Including Communi-cation) and Elements,
298+, for optical directional modulation out-side of an optical waveguide.
