Single carrier 400G/Lambda lithium niobate modulator
The Oclaro single carrier PM-QMZ lithium niobate external modulator is a high electro-optic bandwidth PM-QMZ device that integrates into a hermetic package an input beam splitter, four parallel Mach-Zehnder modulators configured for I-Q modulation, a polarization combiner, and monitor photodiodes for power and bias control.
Key features of the modulator include 3-dB electro-optic bandwidth exceeding 30 GHz; extinction ratio above 25 dB to enable complex modulation formats; insertion loss below 12 dB for high efficiency; and support for L-Band operation similar to all other Oclaro LiNbO3 modulators.
“Oclaro has a proven history in delivering high-speed, high-volume lithium niobate external modulators that customers need to deploy high bandwidth coherent networks up to 400G. This represents another key milestone highlighting our leadership position in lithium niobate components for long haul and metro applications,” said Beck Mason, President, Integrated Photonics Business at Oclaro, Inc.
