OEwaves’ HI-Q® Terahertz Source provides reference frequency outputs tunable over 40- to 110 GHz with unrivaled low phase noise which is independent of frequency. The frequency range is readily extended to 500 GHz and beyond as higher bandwidth photomixers become commercially available.
The unique design of the OEwaves HI-Q® THz source is based on photonic generation of spectrally pure signals leading to phase noise that is independent of output frequency. This is accomplished with our patented technology of semiconductor lasers injection locked to ultrahigh quality factor (Q) crystalline optical whispering gallery mode resonators. The THz Source is frequency stabilized with an internal oscillator at 10
-10 stability level. Alternatively, it could be stabilized to the level of stability of an external LO provided by the user.
With the rapid growth in the areas of 5G and 6G communication, the need for a high performance and stable THz reference source is growing rapidly”, said Lute Maleki, CEO of OEwaves. “This need, combined with the growing needs related to THz characterization of materials are some of the drivers for this offering from OEwaves.”
The high-performance THz source allows enhanced radar system visibility, stable clocking, increased channel capacity for communication systems, high data links, and high capacity and high frequency next generation 5G and 6G wireless systems. This level of performance enables new capabilities for legacy and emerging systems supporting a variety of terrestrial, airborne, and military and commercial space applications. Optional remote fiber optic output is available.
OEwaves will display the HI-Q series of low noise, high stability laser, THz, and RF products, including the HI-Q THz Source, at Photonics West 2025 in San Francisco, Jan. 28 – 30, Booth #3634
