Broadband Fiber-based Entangled Photon Pair Source at Telecom O-band
Changjia Chen, Calvin Xu, Arash Riazi +4
In this letter, we report a polarization-entangled photon-pair source based on type-II spontaneous parametric down conversion at telecom O-band in periodically poled silica fiber (…
Recovering the full dimensionality of hyperentanglement in collinear photon pairs
Changjia Chen, Arash Riazi, Eric Y. Zhu +1
Exploiting hyperentanglement of photon pairs, that is, simultaneous entanglement in multiple degrees of freedom(DOFs), increases the dimensionality of Hilbert spaces for quantum in…
Biphoton shaping with cascaded entangled-photon sources
Arash Riazi, Changjia Chen, Eric Y. Zhu +4
Quantum entanglement is an integral part of quantum optics and has been exploited in areas such as computation, cryptography and metrology. The entanglement between photons can be…
Alignment-free dispersion measurement with interfering biphotons
Arash Riazi, Eric Y. Zhu, Changjia Chen +3
Measuring the dispersion of photonic devices with small dispersion-length products is challenging due to the phase-sensitive, and alignment-intensive nature of conventional methods…
Turn-Key Diode-Pumped All-Fiber Broadband Polarization-Entangled Photon Source
Changjia Chen, Arash Riazi, Eric Y. Zhu +4
In this letter, we report a compact, low-power laser diode-pumped, all-fiber polarization-entangled photon pair source based on periodically-poled silica fiber technology. The all-…
Nanotesla-level, shield-less, field-compensation-free, wave-mixing-enhanced body-temperature atomic magnetometry for biomagnetism
Feng Zhou, Eric Y. Zhu, Yvonne L. Li +2
We report an optical inelastic-wave-mixing-enhanced atomic magnetometry technique that results in nT-level magnetic field detection at temperatures compatible with the human body w…
