Strong Optomechanical Squeezing of Light
Physical Review X, 2013 We create squeezed light by exploiting the quantum nature of the mechanical interaction between laser light and a membrane mechanical resonator embedded in an optical cavity. The radiation-pressure shot noise (fluctuating optical force from quantum laser

Overcoming laser phase noise for low-cost coherent optical communication. [PDF]
Nat CommunAbstractArtificial-intelligence-generated content has driven explosive data traffic growth in data-center interconnects. Traditional direct detection solutions struggle with limited spectral efficiency and distance, prompting the shift to coherent optics for cost-sensitive short-reach links.

Phase noise of diode laser in self-mixing interference
Optics Express, 2005 We investigate the phase noise of a diode laser based on the interferometric self-mixing effect. A detuned Fabry-Perot cavity converts the phase noise into intensity noise, and the noise is measured by the novel method as a function of the amount of feedback and the distance between the target and the laser front facet. Experimental results can be well

Pound–Drever–Hall feedforward: laser phase noise suppression beyond feedback
OpticaPound–Drever–Hall (PDH) laser frequency stabilization is a powerful technique widely used for building narrow linewidth lasers. This technique is, however, ineffective in suppressing high-frequency (>100kHz) laser phase noise detrimental for many applications.

Electronic laser phase noise reduction [PDF]
2013 IEEE Radio Frequency Integrated Circuits Symposium (RFIC), 2013 The first integrated wideband laser phase noise reduction scheme is presented where the laser phase noise is first detected using a photonic chip, processed using an electronic chip, and subtracted from the laser phase in a feed-forward manner. The proof-of-concept experiments on a commercially available 1553nm distributed feedback laser show linewidth

Suppressing laser phase noise in an optomechanical system [PDF]
Frontiers of Physics, 2021 We propose a scheme to suppress the laser phase noise without increasing the optomechanical single-photon coupling strength. In the scheme, the parametric amplification terms, created by Kerr and Duffing nonlinearities, can restrain laser phase noise and strengthen the effective optomechanical coupling, respectively.

Simple Noise Mitigation Scheme for Coherent Optical DMT Signal Transmission System
IEEE Access, 2020 We propose and experimentally demonstrate a noise mitigation scheme for coherent optical discrete multitone (DMT) signal transmission system. The proposed scheme can mitigate the laser phase noise and additive white Gaussian noise (AWGN) simultaneously ...
