Abstract

See full text

The invention relates to optical waveguide switches wherein input light propagating in an input waveguide may be switched between two output waveguides by means of a carrier-induced total internal reflection. The switches utilizes a double-reflection, or, generally, a multiple-reflection electrode to reduce the light deflection angle at each reflection interface, thereby enabling to increase the light switching angle and/or decrease the power consumption of the switch.
