Development of plasmonic racetrack resonators with a trench structure

摘要

We fabricated a plasmonic racetrack resonator with a trench structure, evaluated it at visible wavelengths, andobserved its operation at these wavelengths. Trench channel plasmon polaritons were stored in the racetrackresonator when incident light irradiated the input port. The plasmonic racetrack resonator with a trench struc-ture can be fabricated in only a few steps, and the resulting increase in the coupling coefficient has potentialapplications in optical integrated circuits.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
