Extinction ratio of magneto-optical modulator
ER is one of the most important parameters of the modulator, which is defined as the ratio of maximum to minimum of the optical transmission power when it is operated asON- andOFF-state, respectively. A magnetic fluid (MF) film and a section of a polarization-maintaining fiber (PMF) are inserted into the structure to generate a suitable sinusoidal. By integrating high-Verdet polymer-coated magnetic nanoparticles onto high-Q Si 3 N 4 microring resonators, we have successfully demonstrated preliminary proof-of-concept for a magneto-optic (MO) modulator with extinction ratios up to 4. 75dB for on-resonance wavelength positions. © 2021 The Author.
