Description
The plasmonic Mach-Zehnder Modulator (MZM) features two carefully engineered arms that balance each other to enhance or subtarct each other to achieve best extinction ratio for applications in measurement instruments, radio-over-fiber (RoF), high-data-rate optical transmission or microwave photonics setups (MWP). Polariton offers the product in balanced and C band variant.
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.
Delivered as a chip or semi-packaged chip, this product can be tailored to your needs.
