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…
Multi-Octave Frequency Comb from an Ultra-Low-Threshold Nanophotonic Parametric Oscillator
Ryoto Sekine, Robert M. Gray, Luis Ledezma +3
Ultrabroadband frequency combs coherently unite distant portions of the electromagnetic spectrum. They underpin discoveries in ultrafast science and serve as the building blocks of…
Mode-locked laser in nanophotonic lithium niobate
Qiushi Guo, Ryoto Sekine, James A. Williams +8
Mode-locked lasers (MLLs) have enabled ultrafast sciences and technologies by generating ultrashort pulses with peak powers substantially exceeding their average powers. Recently,…
Visible to Ultraviolet Frequency Comb Generation in Lithium Niobate Nanophotonic Waveguides
Tsung-Han Wu, Luis Ledezma, Connor Fredrick +6
The introduction of nonlinear nanophotonic devices to the field of optical frequency comb metrology has enabled new opportunities for low-power and chip-integrated clocks, high-pre…
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…
Quadratic-soliton-enhanced mid-IR molecular sensing
Robert M. Gray, Mingchen Liu, Selina Zhou +3
Optical solitons have long been of interest both from a fundamental perspective and because of their application potential. Both cubic (Kerr) and quadratic nonlinearities can lead…
