A racetrack resonator, several hundred nanometers in size and composed of plasmonic waveguides is presented. The wavelength spectrum of the plasmonic racetrack resonator has been numerically evaluated by using finite-difference time-domain method. As compared to the conventional plasmonic ring resonator, the output light intensity of the proposed plasmonic racetrack resonator is greater by almost one order of magnitude. The cavity mode of the plasmonic racetrack resonator has also been investigated.

Abstract A design of all-optical half-subtractor (AOHS) is presented based on two-dimensional (2-D) photonic crystal (PhC) waveguides without using optical amplifiers and nonlinear materials. It is an essential component of various photonic integrated circuits. The design of AOHS circuit is based on beam interference principle, using square lattice of Y-shaped and T-shaped waveguides with silicon dielectric rods in air substrate. It is validated through finite-difference time-domain and using MATLAB simulations.
