Silicon optical modulators Nature Photonics
A ring modulator placed in a Fabry-Perot laser cavity was reported to eliminate the tuning power by automatic matching of the laser wavelength with that of the ring modulator while maintaining high-speed ultralow-power modulation of a Si microring modulator. Optical ring, cylindrical, and spherical resonators have … See more An optical ring resonator is a set of waveguides in which at least one is a closed loop coupled to some sort of light input and output. (These can be, but are not limited to being, waveguides.) The concepts behind … See more To understand how optical ring resonators work, we must first understand the optical path length difference (OPD) of a ring resonator. This is given as follows for a single-ring ring resonator: $${\displaystyle \mathbf {OPD} =2\pi rn_{\text{eff}}}$$ See more Due to the nature of the optical ring resonator and how it "filters" certain wavelengths of light passing through, it is possible to create high-order optical filters by cascading many … See more • Animation of optical ring resonator on YouTube See more Optical ring resonators work on the principles behind total internal reflection, constructive interference, and optical coupling.
