Abstract
A silicon racetrack resonator modulator, based on phase-match control, is proposed. The device is comprised of a straight waveguide evanescently coupled to a ring resonator in the shape of a racetrack. A PN junction, formed in the straight waveguide, is used to control the degree of phase-match in the coupler. Consequently, the coupling, and hence the power transmission, is controlled by the voltage across the PN junction. The predicted free spectral range and switching voltage are, respectively, 0.4 nm and 7.5 Volt, while the device dimensions are approximately 0.7 mm by 0.15 mm. The device behavior is analyzed using two different analytic approaches for the coupling, the results of which are compared to numerical simulations.
