Optical ring modulator
WebAbstract. Optical modulation with 8dB extinction ratio and 3dB insertion loss is achieved by applying a 1.5-V pp drive voltage to a 10-μm ring with embedded MOS capacitor. Open-eye diagrams are obtained at 3Gbps. M. Webster, K. Lakshmikumar, C. Appel, C. … WebModeling a Ring Resonator Tool Used: FullWAVE A ring resonator is a very useful device that acts as a high-Q filter for applications that require wavelength selectivity. This type of device has many resonances, and only these resonant wavelengths are coupled to the output waveguide.
