OE3720 - THz Source
HI-Q® THz SOURCE
The OEwaves HI-Q® THz Source features a unique design that generates spectrally pure millimeter-wave signals using photonic techniques, with phase noise that remains consistent across frequencies. This is enabled by OEwaves’ patented technology, where semiconductor lasers are injection-locked to ultra-high-Q crystalline optical whispering gallery mode resonators.
This high-performance, DC-driven THz source enhances radar visibility, enables stable clocking, boosts communication channel capacity, and supports high-frequency, high-bandwidth next-generation wireless systems. Its compact form factor unlocks new capabilities for both legacy platforms and emerging applications across terrestrial, airborne, space, and small satellite systems.
