PLASMON TRANSMISSION FILTER

摘要

PURPOSE: A plasmon transmission filter is provided to reflect or progress a plasmon wave by transmitting the plasmon wave with a specific wavelength to a plasmon resonator. CONSTITUTION: A mode cutoff area(11) and a mode progress area(12) are formed on a core(10). A cladding(20) surrounds the core. The relative dielectric constant of the mode cutoff area is different from the relative dielectric constant of the mode progress area. The plasmon wave of a preset wavelength is selectively progressed through the mode cutoff area and the mode progress area.
