HyperLight Introduces 110 GHz Reference IQ Modulators covering optical O, C and L wavelength bands for 240 GBaud Class Applications

CAMBRIDGE, Mass.-- September 30, 2025  -- HyperLight, creator of the TFLN Chiplet™ platform, today announced the launch of the industry’s first 110 GHz IQ packaged modulators, available in both standard and low-Vπ versions. These 110 GHz IQ modulators mark another industry milestone by enabling next-generation 240 GBaud+ coherent optical communication and advanced test systems with unprecedented performance.

The new IQ modulators are the first of their kind to provide 125 GHz operational bandwidth. They also feature a record low half-wave voltage as low as 1.7 V, optimized for the limited voltage swing of the high-baud-rate Arbitrary Waveform Generator (AWG) systems. They deliver the bandwidth and signal fidelity required for 240 GBaud-class transmission and ultra-high-speed testing environments. These 110 GHz IQ modulators have been delivered to customers worldwide.

Key Features of HyperLight’s 110 GHz IQ Modulators:

• Single-polarization IQ modulator
• 125 GHz operational bandwidth
• Supports 240 GBaud signaling
• IQ automatic bias controller available, designed for TFLN thermal phase shifter
• Coverage across C/L-band and O-band

Target Applications include:

• 240 GBaud coherent testing
• 110 GHz single sideband modulation

‘With 240 GBaud coherent applications on the horizon, the launch of our 110 GHz IQ Modulator gives customers early and straightforward access to the golden transmitters essential for next-generation coherent testing and development,” says Mian Zhang, CEO of HyperLight, “This breakthrough builds on our proven, high-volume TFLN Chiplet™ platform, the same foundation behind our leading coherent chiplet products. By uniting these technologies, we provide customers with the confidence and flexibility to access the industry’s best commercial-scale TFLN capability, precisely at the form factor and the scale their needs demand.”

The new 110 GHz IQ modulators expand HyperLight’s growing portfolio of ultra-high-speed electro-optic devices, complementing its 110 GHz Intensity and Phase modulator product lines. The launch further underscores HyperLight’s leadership in thin-film lithium niobate (TFLN) technology and its commitment to delivering the future of ultra-fast, energy-efficient optical communications.
