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.…
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…
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…
