Abstract

An optical switch comprises one or more input ports for directing an optical beam into the switch; dispersive means configured to receive said optical beam and which spatially separate the optical beam into individual wavelength components which are routed to an actuator; wherein the actuator is in the form of an array of elongate movable fingers for selectively interfering with individual wavelength components and means are provided to direct optical beams to selected one or more output ports.
