Entangled photon triplets using lithium niobate nanophotonics
Nathan A. Harper, Ayantika Sengupta, Emily Y. Hwang +1
Multiphoton states are needed for quantum communication and computation. Multiphoton states are significantly more difficult to generate than one- and two-photon states because two…
Generation of UV-Vis correlated photon pairs using PP-LaBGeO5
Ricardo Tolentino, Nathan Harper, Scott Cushing
The SHG and SPDC output of a periodically poled bulk LBGO crystal is measured. The SHG efficiency is measured to be (3.52 +/- 0.04) x 10^-3 %/W. The SPDC output is temporally chara…
Temperature-Tunable Entangled Photon Source for Multiplexed Time-Resolved Fluorescence on a Nanophotonic Platform
Ayantika Sengupta, Nathan A. Harper, Emily Y. Hwang +1
Compact, scalable, and multiplexed fluorescence lifetime sensors are of great interest for point-of-care diagnostics. However, current solutions either lack broad-range wavelength-…
Investigation of nanophotonic lithium niobate waveguides for on-chip evanescent wave sensing
Nathan A. Harper, Emily Y. Hwang, Philip A. Kocheril +2
Thin-film lithium niobate is a promising photonic platform for on-chip optical sensing because both nonlinear and linear components can be fabricated within one integrated device.…
Experimental Upper Bounds for Resonance-Enhanced Entangled Two-Photon Absorption Cross Section of Indocyanine Green
Manni He, Bryce P. Hickam, Nathan Harper +1
Resonant intermediate states have been proposed to increase the efficiency of entangled two-photon absorption (ETPA). Although resonance-enhanced ETPA (r-ETPA) has been demonstrate…
Highly efficient visible and near-IR photon pair generation with thin-film lithium niobate
Nathan A. Harper, Emily Y. Hwang, Ryoto Sekine +4
Efficient on-chip entangled photon pair generation at telecom wavelengths is an integral aspect of emerging quantum optical technologies, particularly for quantum communication and…
Entangled Photon Correlations Allow a Continuous-Wave Laser Diode to Measure Single Photon, Time-Resolved Fluorescence
Nathan Harper, Bryce P. Hickam, Manni He +1
Fluorescence lifetime experiments are a standard approach for measuring excited state dynamics and local environment effects. Here, we show that entangled photon pairs produced fro…
Tunable and efficient ultraviolet generation in nanophotonic lithium niobate
Emily Hwang, Nathan Harper, Ryoto Sekine +3
On-chip ultraviolet sources are of great interest for building compact and scalable atomic clocks, quantum computers, and spectrometers; however, few material platforms are suitabl…
Single Photon Scattering Can Account for the Discrepancies Between Entangled Two-Photon Measurement Techniques
Bryce P. Hickam, Manni He, Nathan Harper +2
Entangled photon pairs are predicted to linearize and increase the efficiency of two-photon absorption, allowing continuous wave laser diodes to drive ultrafast time-resolved spect…
