title: Microring resonator composed of vertical slot waveguides with minimum polarization mode dispersion over a wide spectral range.
abstract: This paper proposes the design of a vertical slot waveguide-based optical ring resonator on a silicon photonic platform with minimized polarization mode dispersion (PMD) in the presence of waveguide dispersion over a wide band. Slot waveguides provide more degrees of freedom in the design, thereby achieving the minimum PMD over the communication wavelengths. The minimum PMD leads to nearly identical accumulated phase in the optical ring resonator for quasi-TE and TM modes, and thus the resonant wavelength mismatch between the quasi-TE and TM modes can be minimized from 1510 to 1590 nm.
