摘要

压缩光的产生和应用一直是量子光学的中心目标。与压缩真空相比,明亮(相干)态的强度噪声压缩(“明亮压缩”)相对不发达。目前的技术状态通常被限制在狭窄的工作波长范围内,并且不支持强腔内和宽带输出压缩。在这里,我们展示了具有强烈强度相关耗散的激光器如何支持从红外(IR)到太赫兹(THz)波长的强强度噪声压缩,后者已经避免了量子光的产生。我们的协议实现了强(> 10$ {>} 10$ dB)强度噪声压缩的腔内量子态以及超过千兆赫带宽的输出压缩。此外,我们还展示了相同的系统如何支持自脉冲和双稳性,从而能够在平均场和噪声域中控制光。我们的协议可以在低噪声通信、腔QED和跨电磁频谱的量子传感方面取得进展。

Strong broadband intensity noise squeezing from infrared to terahertz frequencies in lasers with nonlinear dissipation
The generation and application of squeezed light have long been central goals of quantum optics. Intensity noise squeezing of bright (coherent) states (“bright squeezing”), in contrast to squeezed vacuum, is relatively underdeveloped. The current state of the art has generally been restricted to narrow operating wavelength ranges and does not natively support strong intracavity and broadband output squeezing. Here, we show how lasers with sharp intensity-dependent dissipation can support strong intensity noise squeezing from infrared (IR) to terahertz (THz) wavelengths, the latter of which has eluded quantum light generation. Our protocol realizes strongly ( > 10 ${ >} 10$ dB) intensity noise-squeezed intracavity quantum states as well as output squeezing surpassing gigahertz bandwidths. Furthermore, we show how the same systems also support self-pulsing and bistability, enabling control of light in both the mean field and noise domains. Our protocol could enable advances in low-noise communication, cavity QED, and quantum sensing across the electromagnetic spectrum.
