Optical Modulators

The GK130G is a Quad-Channel 130 GBaud High-Bandwidth coherent driver modulator integrated with an RF driver, based on Thin-Film LiNbO3 chip. It is designed for 400/800 Gb/s/1.2Tb/s coherent optical transport systems and transceivers, with Baud rate over 130G per channel.

The GKF10 is a single drive modulator designed for high bit rate advanced metro to long haul communication systems that requires the superior performance. The GKF10 modulator contains an integrated photodetector that may be used to set and lock the DC bias on the modulator as well as provide an estimate of the modulator output optical power.

WXG Broadband Analog Intensity Modulators combine high linearity with low driving voltage and small footprint, covering frequency range from 20 GHz to beyond 40 GHz (AM20-XT: 20 - 30 GHz; AM40-XT: > 30 GHz). The experience and know-how of WXG engineers is available to customize our products to the customer’s specificrequirements.

WXG broadband phase modulators combine high linearity with low driving voltage and small footprint, covering all the frequency range up to 10 GHz.

The 40G-IQ-XT modulator design is based on a dual parallel structure of two Mach-Zehnder modulators embedded in a Mach Zehnder super-structure. Each internal modulator is designed to have EO bandwidth above 20 GHz. Monitor photodiode is provided for automatic bias control.
