Description
The plasmonic Mach-Zehnder Modulator (MZM) featuring a bandwidth beyond 110 GHz makes it a first choice for applications in measurement systems, radio-over-fiber (RoF) and for high-data-rate optical transmission. Polariton offers the product in two variants: balanced and imbalanced.
The optical spectrum of the balanced MZM has a gaussian shape around the central coupling wavelength of its grating couplers. This allows operation in a 3 dB optical bandwidth of around 60 nm. To set the operating point, the balanced MZM contains thermo-optic phase-shifter, which shifts the whole spectrum in the y-axis.
The imbalanced MZM 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 unnecessary.
Delivered as a chip or semi-packaged chip, this product can be tailored to your needs.
