Abstract

We fabricated a plasmonic racetrack resonator with a trench structure, evaluated it at visible wavelengths, and observed its operation at these wavelengths. Trench channel plasmon polaritons were stored in the racetrack resonator 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 potential applications in optical integrated circuits.
