Fig. 1: HyperLight’s 145 GHz intensity modulator for 448Gbps per lane IMDD and 260GBaud coherent applications, with operational electro-optical bandwidth >145GHz, stable bias control, 0.8 mm-connector; available in O-, C-, and L-bands.

As symbol rates and analog bandwidth requirements continue to rise across data center interconnects, AI-driven photonics infrastructure, and laboratory test environments, system architects increasingly require high-performance intensity modulators with more than 130 GHz bandwidth, while remaining practical to deploy. HyperLight’s 145 GHz IM addresses these requirements with greater than 145 GHz bandwidth, a compact packaged form factor, and a 0.8 mm RF connector interface engineered for high-frequency integration.

The 145 GHz Packaged IM is offered across multiple wavelength bands - O-, C-, and L-band and 1µm - supporting broad deployment scenarios in test and system prototyping where wavelength flexibility is important. The product integrates polarization-maintaining (PM) optical fiber and is designed to deliver high extinction ratio, helping improve modulation contrast and measurement clarity in demanding lab and system validation workflows.

The 145 GHz packaged IM incorporates Telcordia qualified TFLN PICs that features industry leading reliability. In addition, the 145 GHz IM is engineered for high optical and RF power handling, enabling use cases that push wideband modulation performance while maintaining robust operation.

“The industry is pushing beyond 100 GHz, and customers need packaged modulators they can trust at those bandwidths,” said Mian Zhang, CEO of HyperLight. “Developing an ultrahigh performance and reliable 145 GHz photonics technology has been a major challenge for the industry. We manufactured 145 GHz intensity modulator by leveraging our industry leading, TFLN Chiplet platform that is anchored on high bandwidth datacom and telecom high-volume applications. Our packaged modulator products give our customers early and reliable access to next-generation high bandwidth photonics capabilities.”

HyperLight’s 145 GHz Packaged IMs are now available in O-, C-, and L-band configurations. 1µm-band configuration is available for pre-ordering. For product details and ordering inquiries, please visit: https://hyperlightcorp.com/products/packaged-modulators
