摘要： An optic switching system and method are presented for controllably directing an incident beam of electromagnetic radiation propagating with a certain solid angle from a primary optical waveguide to a predetermined secondary optical waveguide. A primary reflective concave surface is disposed for receiving the incident beam, reflecting the incident beam and focusing a reflected beam at a primary focusing place. A secondary reflective concave surface having a radius less than a radius of the primary reflective concave surface is disposed for receiving the beam reflected by the primary reflective surface and reflecting this beam to the predetermined secondary optical waveguide. The secondary reflective concave surface is disposed at the place located downstream of the primary focusing place with respect to the direction of propagation of the beam reflected from the primary reflective concave surface. An actuator is operatively connected to one of the reflective surfaces or to both and is adapted for controlling a selective displacement of the respective reflective surface relative to the optical beam that impinges thereon.
