Study of Optical Resonant Micro-ring Cavity Based on SOI and Application

[[abstract]]In this thesis, we integrated development of optical waveguide for the active and the passive device has become the future trend. We propose optical waveguide components for optical micro-ring resonator building on silicon-on-insulator (SOI) wafers, and also integrated air-bridge structure and the simulation is based on the well-known Finite-difference Time Domain (FDTD) technique. We used the free-carrier plasma dispersion effect and Schottky diode structure to modulate our filter and optical switch device; we devote our attraction on the electro-optical micro-ring resonator to apply in optical communication system. In sensing applications, we also design the geometric structure of resonance cavity to see different resonances are discussed in the thesis. We design the micro-ring their have small size, low cost, and potential for high sensitivity make them attractive for bio-sensing applications.
