GigOptix: samples LX8901 100-Gbps TFPS modulator

The LX8901 is a serial 100-Gbps differential phase-shift keying (DPSK) MZM implemented using GigOptix's proprietary Thin Film Polymer on Silicon (TFPS) technology. The device provides optical bandwidth of over 65 Hz with low drive voltage, the company says.

The LX8901 enables a number of ultra-high-frequency applications in the field of microwave photonics such as antenna remoting, RF beam steering, phased array radar, ultra-high-frequency signal sampling and mixing that are not viable using other modulator technologies, such as Indium Phosphide and Lithium Niobate, GigOptix asserts.

Eric Miller, general manager of GigOptix Bothell stated, "We are delighted to bring yet another TFPS modulator to production to serve the mil/aero markets. Moreover, with our recent shipments we are seeing interest for our devices from new markets, especially in microwave photonics and instrumentation and measurement, since the device's high bandwidth can enable complex high-fidelity signal generation at ultra-high speeds."
