By combining compact laser sources with sub-1 ml volume and ultrastable optical cavities, this work enables extremely compact and robust ultrastable laser systems with applications in low phase noise microwave generation, sensing, and satellite ranging. The Laser Light Screen System faces critical technical challenges in high-speed, long-range target detection: when a target passes through the light screen, weak light flux variations lead to significantly degraded signal-to-noise ratios (SNRs). Traditional signal processing algorithms fail to. Ultra-low-noise microwave signals play a driving role in the development of modern scientific technologies such as radar, communication, and sensing. On-chip photonic integration provides an attractive approach for the implementation of ultra-low-noise microwave signal sources with attractive added. We demonstrate thermal-noise-limited direct locking of a semiconductor distributed feedback (DFB) laser to a sub-1 mL volume, ultrastable optical cavity, enabling extremely compact and simple ultrastable laser systems. Using the optoelectronic laser locking method, we realize over 140 dB. Here we address these shortcomings with a hybrid optoelectronic approach that combines simplified optical frequency division with direct digital synthesis to produce tunable low-phase-noise microwaves across the entire X-band (8–12 GHz).
