Distinguishing thermal and pseudothermal light by testing the Siegert relation
Xi Jie Yeo, Justin Yu Xiang Peh, Darren Ming Zhi Koh +2
Thermal light, including blackbody radiation and spontaneous emission, exhibits photon bunching. Thermal light sources, however, typically yield low spectral densities, limiting th…
Clock Synchronization with Weakly Correlated Photons
Justin Yu Xiang Peh, Darren Ming Zhi Koh, Zifang Xu +3
Clock synchronization is necessary for communication and distributed computing tasks. Previous schemes based on photon timing correlations use pulsed light or photon pairs for thei…
Near-lossless method for generating thermal photon-bunched light
Xi Jie Yeo, Darren Ming Zhi Koh, Justin Yu Xiang Peh +2
Thermal light sources exhibiting photon bunching have been suggested for sensing applications that exploit timing correlations of stationary light, including range finding, clock s…
Direct measurement of coherent light proportion from a practical laser source
Xi Jie Yeo, Eva Ernst, Alvin Leow +4
We present a technique to estimate the proportion of coherent emission in the light emitted by a practical laser source without spectral filtering. The technique is based on measur…
Practical Quantum Sensing with Thermal Light
Peng Kian Tan, Xi Jie Yeo, Alvin Zhen Wei Leow +2
Many quantum sensing suggestions rely on temporal correlations found in photon pairs generated by parametric down-conversion. In this work, we show that the temporal correlations i…
Distributing Polarization Entangled Photon Pairs with High Rate over Long Distance through Standard Telecommunication Fiber
Lijiong Shen, Chang Hoong Chow, Justin Yu Xiang Peh +3
Entanglement distribution over long distances is essential for many quantum communication schemes like quantum teleportation, some variants of quantum key distribution, or implemen…
A wide-range wavelength-tunable photon-pair source for characterizing single-photon detectors
Lijiong Shen, Jianwei Lee, Antony Winata Hartanto +2
The temporal response of single-photon detectors is usually obtained by measuring their impulse response to short-pulsed laser sources. In this work, we present an alternative appr…
Breakdown flash at telecom wavelengths in InGaAs avalanche photodiodes
Yicheng Shi, Janet Zheng Jie Lim, Hou Shun Poh +4
Quantum key distribution (QKD) at telecom wavelengths (1260-1625nm) has the potential for fast deployment due to existing optical fibre infrastructure and mature telecom technologi…
Characterization of very narrow spectral lines with temporal intensity interferometry
Peng Kian Tan, Christian Kurtsiefer
Context: Some stellar objects exhibit very narrow spectral lines in the visible range additional to their blackbody radiation. Natural lasing has been suggested as a mechanism to e…
Optical Intensity Interferometry through Atmospheric Turbulence
Peng Kian Tan, Aik Hui Chan, Christian Kurtsiefer
Conventional ground-based astronomical observations suffer from image distortion due to atmospheric turbulence. This can be minimized by choosing suitable geographic locations or a…
Measuring Temporal Photon Bunching in Blackbody Radiation
Peng Kian Tan, Guang Hui Yeo, Hou Shun Poh +2
Light from thermal black body radiators such as stars exhibits photon bunching behaviour at sufficiently short timescales. However, with available detector bandwidths, this bunchin…
