A beam deflector 1 for a beam of light 9 comprises: a first plate of electro-optical material disposed between a pair of electrode arrangements and a pair of plano-parallel mirrors, the refractive index of the electro-optical material being variable by the application of electric voltages, wherein a first mirror of the pair facing towards the incident light has a lower reflectivity than the second mirror, the first or second mirrors comprising a plurality of dielectric layers having refractive indices different from each other. Further, a switching system comprises: a plurality of terminals (53) for optical signals and beam deflectors (1) allocated to each other in pairs, each beam deflector being controllable such that it deflects the light beam (9) directed thereto into a selectable direction in order for the beam to enter at least one selected terminal end (55).
A beam deflector for deflecting an incident beam of light of a predetermined wavelength (λ), comprising a first plate of electro-optical material disposed between a pair of electrode arrangements and a pair of plano-parallel mirrors, the refractive index of the electro-optical material being variable by the application of electric voltages to the electrode arrangements, wherein a first mirror of the pair of mirrors facing towards the incident light beam has a lower reflectivity than the second mirror of the pair of mirrors, wherein at least one of the first and the second mirror comprises a plurality of layers of dielectric material, wherein the refractive indices of the dielectric materials of adjacent layers differ from each other, and wherein the incident beam is deflected in a selectable direction.
A beam deflector for deflecting an incident beam of light comprising a first plate of electro-optical material disposed between a pair of electrode arrangements and a pair of plano-parallel mirrors, the refractive index of said electro-optical material being variable by the application of electric voltages to the electrode arrangements wherein a first one of the two electrode arrangements comprises two sets of stripe electrodes, the stripe electrodes of each set of stripe electrodes being juxtaposed in parallel to each other and directions of extension of the stripe electrodes of different sets of stripe electrodes extend transversely, in particular orthogonally, to each other.
