Waveguide ring resonator is the sensing element of resonant integrated optical gyroscope (RIOG). This paper reports a polymer-based ring resonator with a low propagation loss of about 0.476 dB/cm for RIOG. The geometrical parameters of the waveguide and the coupler of the resonator were optimally designed. We also discussed the optical properties and gyroscope performance of the polymer resonator which shows a high quality factor of about 105. The polymer-based RIOG exhibits a limited sensitivity of less than 20 deg/h for the low and medium resolution navigation systems.

In this paper, we present the design of a novel hybrid dielectric-metal-dielectric waveguide, which consists of a metal stripe sandwiched between low-high dielectric layers. Its modal characteristics are investigated using the finite element method at the telecom wavelength. Simulations show that the dielectric contrast near the metal stripe results in a strongly confined hybrid plasmonic mode with sub-micron mode size and low propagation loss. The effects of geometrical parameters are analyzed systematically and the properties of directional couplers based on such hybrid waveguide are also investigated. The proposed structure could be useful candidates for various integrated optical devices and enable many applications such as electro-optic modulation, switching, sensing and more.

In this paper, we develop a technique for realizing multi-centimeter-long lithium niobate on insulator (LNOI) waveguides with a propagation loss as low as 0.027 dB/cm. Our technique relies on patterning a chromium thin film coated on the top surface of LNOI into a hard mask with a femtosecond laser followed by chemo-mechanical polishing for structuring the LNOI into the waveguides. The surface roughness on the waveguides was determined with an atomic force microscope to be 0.452 nm. The approach is compatible with other surface patterning technologies, such as optical and electron beam lithographies or laser direct writing, enabling high-throughput manufacturing of large-scale LNOI-based photonic integrated circuits.
