Description

The plasmonic Ring Resonator Modulator (RRM) is an ideal solution for high-speed electro optic conversion in the C band. Featuring a bandwidth of beyond 85 GHz makes it a first choice for applications in measurement systems, radio-over-fiber (RoF) systems and for high-data-rate optical transport.

The RRM has a resonant spectrum with peaks and extinctions. This allows for a change of the operating point by tuning the wavelength of the laser source, making an additional voltage source obsolete.
