FastPhide Photonics | Ultrafast Optical & THz Devices

Breaking the trade-off between speed and efficiency

The future of communication hinges on performance — bandwidth, responsivity, and energy efficiency. Our photodetectors break traditional trade-offs through structural and material innovation.

Using a disruptive MUTC design, we overcome hole transport bottlenecks, achieving over 200 GHz bandwidth per lane — while maintaining a responsivity of 0.8 A/W — enabling 400 Gbit/s per channel and beyond.

Full-Chain Innovation in III-V Photonics

Our team deliver innovation across the full photonic device development flow, including epitaxial structure design, advanced III-V processing, ultrafast RF characterization, and broadband packaging up to 300 GHz. With years of accumulation in the design and fabrication III-V photodiodes , we have built a robust foundation for rapid product iteration and performance breakthroughs.

Advanced packaging solutions from DC to THz

We provide high-frequency packaging technologies supporting signal integrity from DC up to terahertz bands. Our solutions ensure low loss, wide bandwidth, and excellent thermal and electrical performance — enabling reliable integration of ultrafast photonic devices into real-world systems.

Pioneering III-V/Si III-V/TFLN Heterogeneous Integration

We develop advanced integration techniques that combine the performance of III-V materials with the scalability of silicon photonics and the electro-optic efficiency of thin-film lithium niobate (TFLN), enabling next-generation photonic chips with unmatched speed and functionality.
