Active electro-optical wavelength-selective mirrors and active electro-optic wavelength-selective filters

摘要

This invention discloses an electro-optically controlled optical element (300) including a diffraction grating (130); and a planar waveguide (122) associated with the diffraction grating (130), the diffraction grating (130) and the planar waveguide (122) being configured to undergo resonance of at least one of transmitted or reflected light at a wavelength which is selectable by means of an electrical input.
