The design, fabrication and measurement of a silicon-on-insulator (SOI) two-dimensional photonic crystal ring resonator are demonstrated in this study. The structure of the photonic crystal is comprised of silicon nano-rods arranged in a hexagonal lattice on an SOI wafer. The photonic crystal ring resonator allows for the simultaneous separation of light at wavelengths of 1.31 and 1.55μm. The device is fabricated by e-beam lithography. The measurement results confirm that a 1.31μm/1.55μm wavelength ring resonator filter with a nano-rod photonic crystal structure can be realized.
