研究目的
To model a modified microring resonator (Panda structure) using both silicon and nonlinear material (Chi2) to generate four-wave mixing through nonlinear optical interaction.
研究成果
The modified microring resonator (Panda structure) successfully generates four-wave mixing through nonlinear optical interaction, with the nonlinear material showing better power transferring performances than silicon. The study highlights the potential applications in high-speed communications and sensors, with a noted time delay of 9884.3 fs when using nonlinear materials.
研究不足
The study is limited by the computational consumption of the FDTD technique, especially for 3-D nonlinear dispersive resonators. The practical applications may be constrained by the sensitivity of nonlinear materials to input mode profile and field propagating in the gap region between the waveguide and the rings.
