Our Products & Systems

Lithium Niobate Phase Modulators
Our ultra-high-speed Lithium Niobate phase modulators together with a traveling-wave design and an advanced index-matching technologies enable optical response over the entire millimeter-wave spectrum (up to 500 GHz). We provide a standard modulator package, as well as customized modulator chips, packages and services for integration of modulators and RF amplifiers.

High-Speed Photodiodes
Our high-speed UTC photodiode products offer world leading power handling capability and linearity. They are ideal for RF photonic links, photonic RF generation and high-speed, high-linearity photodetection.

High-Speed RF Link
Utilizing our industry-leading modulator and photodiode technologies, our link products offer broadband, high-fidelity, point-to-point analog signal connection over long distance. They are ideal for commercial and military applications where high performance is required under limited SWaP and harsh environment.

Wideband RF Signal Synthesizers
PSI offers a novel tunable optical paired source (TOPS) system that provides two optical phase coherent signals to support photonically-enabled RF signal generation over very broad bandwidths (1 – 100 GHz). The high-performance RF generation capabilities are suitable for a wide variety of analog and digital RF photonic applications.

TECHNOLOGY
PSI’s technology uses efficient electro-optic modulators and advanced photodetectors for our photonic devices. Our RF system utilizes a special optical up-conversion technology that allows phased array antenna systems to visually map the RF environment, reducing interference and enabling more efficient use of frequencies in a crowded space.
COMMUNICATIONS
PSI’s up-conversion technology converts RF signals into spatial sectors based on their angle of arrival with high precision. It can process a large number of beams simultaneously with a wide bandwidth, making it ideal for advanced wireless communication systems like 5G and beyond.
IMAGING
PSI’s technology allows a phased array antenna system to function like a video camera, providing real-time video of the RF scene. This can be used to see through objects and environmental conditions, detect concealed items, assist with aircraft navigation in poor visibility, and for various quality control and testing purposes in manufacturing.
