C Band 80 GHz IQ Modulator
IQM-P80
Dive into Polariton’s coherent modulation products for high bandwidth and symbol rate, simplifying transceiver design and reducing power dissipation. This packaged modulator is ideal for prototypes and proof of concept, but has a lower EO bandwidth compared to the chip variant.
Key Features
-
3-dB electro-optic bandwidth >80 GHz
-
C-band operation
-
Lumped, low-capacitance RF design

Differential drive
Description
The plasmonic differential-drive IQ (in-phase and quadrature) electro-optic modulator (EOM) is the choice for high-speed coherent electro-optic conversion in the C band. Featuring a bandwidth of >80 GHz, it supports applications by modulating IQ symbols, hence outputting an amplitude and phase modulation.
Driving the chip with the signal and with its inverted version (differential-drive) will provide the best modulation efficiency, specifically since most drivers provide the inverted version of the signal from the start.
Delivered as a chip or semi-packaged chip, this product can be tailored to your needs.

* 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 20°C with a Vπ degradation <10%.
