摘要

This paper presents an electrode design of a new photodetector operating at millimeter-wave ragne. By taking the advantages of narrow band operation, the proposed photodetector is designed to have cascaded resonant structure and a reflector to achieve high RF output. Resonators and reflector are realized by usign one-fourth wavelength shorted stubs and an open stubs of coplanar waveguide, respectively. Velocity matching between optical waves and detected millimeter wave signals are performed by introducing an S-shaped meandering transmission lien for the photocurrents.
