Plasmonic Ring Resonator Modulator black

Description

The plasmonic Ring Resonator Modulator (RRM-P70) is an ideal solution for high-speed electro optic conversion in the O and C band. Featuring a bandwidth of beyond 70 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.

* Plasmonic modulators are high-impedance devices. Twice the voltage provided by a 50-Ohm signal source will drop across the plasmonic modulator. Using a DC source or a high-impedance-matched driver, double the voltage is required to switch the modulator from the on to the off state.

** Operation time of 8000 h at 85°C with a V_π degradation <10%.
