PHOTONIC DEVICE OF USING SURFACE PLASMON

摘要

PURPOSE: An optical device using surface Plasmon is provided to implement a switching by sensing the difference of currents flowing in a channel according to incident light. CONSTITUTION: A gate dielectric layer(120) is formed on a gate electrode. A channel region(130) is formed on the gate dielectric layer. A surface Plasmon layer(140) transmits energy to the channel region. A source electrode is formed on one side of the surface Plasmon layer. An optical device includes a drain electrode facing the source electrode.
