RUI: Amplitude Squeezing of Pulsed, Vertical-Cavity, Surface-Emitting Lasers

这个RUI项目的重点是垂直腔面发射激光器（VCELs）产生的光的幅值压缩状态，特别是在什么条件下脉冲VCSEL产生的噪声最少，以及为什么会这样。为此，将彻底地表征VCSEL脉冲的噪声行为。激光器将在不同的驱动和反馈条件下工作，并测量噪声行为的时间演变。测量激光中幅相噪声之间的耦合，并采用幅相解耦技术来降低激光噪声。

This RUI project focuses on the generation of amplitude-squeezed states of light from vertical-cavity, surface-emitting lasers (VCELs), and, in particular, on what conditions produce the lowest amount of noise from a pulsed VCSEL and why this is the case. To this end the noise behavior of the VCSEL pulses will be thoroughly characterized. The laser will be operated under differing drive and feedback conditions, and the time evolution of the noise behavior will be measured. Coupling between amplitude and phase noise in the laser will be measured, and the technique of amplitude-phase decoupling will be used to reduce the laser noise.
