発明の名称 (英語) OPTICAL DEVICE USING NANOCARBON MATERIAL
発明の概要(英語) The present invention provides an optical device which is capable of operating at high speed. An optical device according to the present invention comprises: a first optical waveguide which is connected to an input light port; a second optical waveguide which is connected to a first output light port; a third optical waveguide which is connected to a second output light port; an optical component which optically connects the first optical waveguide to at least one of the second optical waveguide and the third optical waveguide; a nanocarbon material which is provided at least in an area where the optical component is arranged; and a pair of electrodes which apply an electrical signal to the nanocarbon material. The optical path is switched between the first output light port and the second output light port by means of application of an electrical signal.
従来技術、競合技術の概要(英語) BACKGROUND ART
Graphene, carbon nanotubes (CNT) nano-carbon materials such as a light-emitting element, the light source, and the photocoupler has been proposed (for example, see Patent Document 1 and Patent Document 2). A nano-carbon material and the heating by current application is high speed, a continuous spectrum in a wide wavelength range by the black-body radiation (white light) can be obtained.
On the other hand, the fine silicon waveguide on the substrate in silicon photonics optical circuits are integrated and have garnered attention. Silicon photonics technology has been used in various fields, WDM(Wavelength Division Multiplexing: wavelength division multiplexing) method is used in optical communication networks of many small optical module or the like have been developed.
A silicon waveguide of the graphene nano-heater can be placed directly onto an optical phased array is to enhance the heating efficiency are known (for example, see Non-Patent Document 1).
