Based on theoretical predictions on the appearance of antibunching before the laser threshold at the nano- and microscale, we analyze the amount of photon-number squeezing naturally produced in the laser emission. Up to 3 dB photon number noise reduction is obtained in comparison with the coherent emission, with output power in the range of pW and with negligible effects due to pump fluctuations. The scheme requires a moderately high Q cavity and holds promise for the construction of a simple and effective photon-number squeezed source.

纳米和微型激光器中的光子数压缩

基于对纳米级和微米级激光阈值之前出现反聚束的理论预测，我们分析了激光发射中自然产生的光子数压缩量。与相干发射相比，可获得高达 3 dB 的光子数降噪，输出功率在 pW 范围内，并且由于泵浦波动而产生的影响可以忽略不计。该方案需要一个中等高的 Q 腔，并有望构建简单有效的光子数压缩源。
