▎ 摘　　要

NOVELTY - The filter has a filter main body provided with a conductor, a graphene part and an interference peak electrode. The conductor is provided with a conductive core and a cladding part. The cladding part is covered on the conductive core. The cladding part is connected with a side part of a micro-resonator. A cavity port of the micro-resonator is paved with the grapheme part. The graphene part transmits a processing signal to the conductor. The micro-resonator is turned to realize interference peak wave in the filter main body. The cladding part is vertically provided with to a bottom surface. USE - Graphene based electric control wavelength adjusting-type ultra-narrow band pass light filter. ADVANTAGE - The filter increases band pass filter center wavelength tuned precision and reduces response time to obtain extremely narrow band pass width. DESCRIPTION OF DRAWING(S) - The drawing shows a partial sectional view of a graphene based electric control wavelength adjusting-type ultra-narrow band pass light filter.
