Optical deflection element and optical switch

Abstract

A light deflection element is shaped to include: a prism electrode disposed on an optical waveguide; a first photonic crystal structure disposed in front of the prism electrode in a light propagation direction and at a position after light passes through the prism electrode; a control electrode via The optical waveguide on the first photonic crystal structure is arranged facing the opposite electrode layer; and the second photonic crystal structure is arranged on the side of the prism electrode parallel to the light propagation direction.

Description

[0001] Cross References to Related Applications [0002] This application is based upon and claims the benefit of priority from prior Japanese Patent Application No. 2004-311365 filed on October 26, 2004, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an optical deflection element for deflecting light and an optical converter for outputting an input optical signal to a desired channel. Background technique [0004] In recent years, photonic networks have increasingly required high-speed driving and high capacity than before, where optical signals have a wide frequency band and are multiplexed, so transmission equipment for photonic networks is also required to be multi-channel and high-speed driven. In addition, an optical cross-connect device used as a photonic network node is required to increase the number of channels and switch at a higher speed, so an optical converter such as Japanese Patent ...
