Long considered a serious technical challenge, superradiance could actually help quantum devices go even further.

Physicists have discovered a method to utilize the quantum phenomenon, superradiance, to generate powerful, long-lasting microwave signals.

A high-level schematic of the photonic integrated chip, developed by the Gaeta lab, for all-optical optical frequency division, or OFD—a method of converting a high-frequency signal to a lower ...

Optoelectronic oscillators (OEOs) represent a pivotal technology at the intersection of photonics and microwave engineering. By exploiting the long delay lines provided by optical fibres and high‐Q ...

Today, wireless communications play an increasingly important role in our daily lives. For future “freewheeling” sixth generation (6G) wireless communications, the hybrid communication systems that ...

San Ramon, CA — Giga-tronics has introduced the 2500B series microwave signal generators which cover 100 kHz to 50 GHz, with extremely low phase noise, high rejection of harmonics, sub-harmonics and ...

Vector modulation is increasingly used in microwave and satellite communication applications, but generating vector-modulated signals for measurement can be difficult and expensive. However, using ...
