▎ 摘　　要

NOVELTY - Polarizer (p1) (100) comprises: a substrate (110); a first dielectric layer (120) positioned on the substrate; a second dielectric layer (130) positioned on the first dielectric layer; an optical waveguide (140) positioned in the second dielectric layer and for transmitting incident light; a third dielectric layer positioned on the second dielectric layer; and a graphene layer positioned corresponding to the optical waveguide. USE - The polarizer (p1) is useful: as a transverse electric-mode pass polarizer for passing only a transverse electric mode component (claimed); and for polarizing light. ADVANTAGE - The polarizer (p1) exhibits wide wavelength selectivity and bandwidth. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a polarizer (p2) comprising: a substrate; a first dielectric layer positioned on the substrate; an optical waveguide positioned in the first dielectric layer and for transmitting incident light; and a graphene layer positioned corresponding to the optical waveguide and for polarizing the light transmitted from the optical waveguide. DESCRIPTION OF DRAWING(S) - The figure shows a perspective view of the polarizer. Polarizer (100) Substrate (110) First dielectric layer (120) Second dielectric layer (130) Optical waveguide (140)
