▎ 摘　　要

NOVELTY - The device has a main body provided with an optical fiber isolator that is connected with an end of an optical fiber circulator. Another end of the optical fiber circulator is connected with an optical fiber grating sensor and a spectrum analyzer. A broadband light source i.e. ASE light source emits light through the optical fiber isolator and the optical fiber circulator, where output power of the broadband light source is greater than 13dBm. A fiber Bragg grating sensor i.e. fiber grating clamp determines two different wavelengths. An electrode controls electrode gate region. USE - Graphene electrode discharge and coated optical fiber grating based wavelength switch device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene electrode discharge and coated optical fiber grating based wavelength switch device.
