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.…
