NANOSENSOR BASED ON RESONANCE AND SURFACE PLASMON EFFECTS

摘要

An optical biosensor inclues a photonic crystal structure defining a photonic crystal optical waveguide (18) using a plurality of air cylinders (16). The waveguide operates a s a resonance type biosensor. The waveguide may have a spiral form. At least one (5) metallic layer (30) may be deposited along the waveguide for cooperating with the waveguide as a surface plasmon sensor.
