TL;DR: Th thin-film-based ultraefficient periodically-poled lithium niobate nonlinear waveguides are presented, leveraging actively-monitored ferroelectric domain reversal engineering and nanophotonic confinement to address growing demands in integrated-photonic frequency conversion, frequency metrology, atomic physics, and quantum optics.
Journal ArticleDOI
Rejuvenating a Versatile Photonic Material: Thin-Film Lithium Niobate
Journal ArticleDOI
Generation of broadband correlated photon-pairs in short thin-film lithium-niobate waveguides
Bradley S. Elkus,Kamal Abdelsalam,Ashutosh Rao,Vesselin G. Velev,Sasan Fathpour,Prem Kumar,Gregory S. Kanter +6 more
TL;DR: Signal-idler photon pairs with high coincidence-to-accidental count ratios of over 103 are demonstrated on a coarse wavelength-division-multiplexing grid that spans 140 nm by using a 300-μm-long poled region in a thin-film periodically-poled lithium-niobate ridge waveguide bonded to silicon.
Journal ArticleDOI
Linear isolators using wavelength conversion
TL;DR: In this article, the authors introduce a new class of wideband nonmagnetic and linear optical isolators based on nonlinear frequency conversion and spectral filtering among the pump, signal, and idler wavelengths.
Journal ArticleDOI

TL;DR: In this paper, dual-channel phase-shifted Bragg grating filters in the telecom band on thin-film lithium niobate are demonstrated, with an extinction ratio of 27 dB and two channels with close linewidths of about 19 pm.
