Class Information
Number: 385/10
Name: Optical waveguides > Directional optical modulation within an optical waveguide > Electro-optic > Diffraction grating (e.g., bragg)
Description: Subject matter wherein electro-optic directional modulation within a waveguide utilizes an element having a series of very close, equidistant, parallel lines, (i.e., grating) or wherein the waveguide has a grating impressed upon it by an externally applied field.
