Multifunctional meta-optic azimuthal shear interferometer
Linzhi Yu, Sergei Shevtsov, Haobijam Johnson Singh +2
Azimuthal shear interferometry is a versatile tool for analyzing wavefront asymmetries. However, conventional systems are bulky, alignment-sensitive, and prone to nonuniform shear.…
A double-clad ytterbium-doped tapered fiber with circular birefringence as a gain medium for structured light
Iuliia Zalesskaia, Yuhao Lei, Peter G. Kazansky +3
Amplifying radially and azimuthally polarized beams is a significant challenge due to the instability of the complex beam shape and polarization in inhomogeneous environment. In th…
Telecom-band Hyperentangled Photon Pairs from a Fiber-based Source
Changjia Chen, Calvin Xu, Arash Riazi +6
Hyperentanglement, the simultaneous and independent entanglement of quantum particles in multiple degrees of freedom, is a powerful resource that can be harnessed for efficient qua…
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 (…
Complete spatiotemporal and polarization characterization of ultrafast vector beams
Benjamín Alonso, Ignacio Lopez-Quintas, Warein Holgado +4
The use of structured ultrashort pulses with coupled spatiotemporal properties is emerging as a key tool for ultrafast manipulation. Ultrafast vector beams are opening exciting opp…
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-…
Ultrafast Laser Nanostructured ITO Acts as Liquid Crystal Alignment Layer and Higher Transparency Electrode
A. Solodar, A. Cerkauskaite, R. Drevinskas +2
Electrodes with higher transparency that can also align liquid crystals (LCs) are of high importance for improved costs and energy consumption of LC displays. Here we demonstrate f…
Toward A Reconfigurable Quantum Network Enabled by a Broadband Entangled Source
E. Y. Zhu, C. Corbari, A. V. Gladyshev +3
We present a proof-of-principle experimental demonstration of a reconfigurable entanglement distribution scheme utilizing a poled fiber-based source of broadband polarization-entan…
Visible luminescence from hydrogenated amorphous silicon modified by femtosecond laser radiation
Andrey V. Emelyanov, Andrey G. Kazanskii, Mark V. Khenkin +5
Visible luminescence is observed from the composite of SiO2 with embedded silicon nanocrystallites produced by femtosecond laser irradiation of hydrogenated amorphous silicon (a-Si…
Emergence of structural anisotropy in Optical Glasses treated to support Second Harmonic Generation
C. Cabrillo, G. J. Cuello, P. Garcia-Fernandez +5
Structural alterations in v-SiO2 induced by "thermal poling", a treatment which makes the glass able to double the frequency of an impinging infrared light, are revealed by neutron…
Evidence of Microscopic-Scale Modifications in Optical Glasses Supporting Second Harmonic Generation
C. Cabrillo, G. J. Cuello, P. Garcia-Fernandez +5
We explore, by means of inelastic neutron scattering, the extent of changes in dynamic correlations induced by thermal poling of vitreous . The measured vibrational density…
