Ultra-broadband integrated optical parametric amplifier for quantum sensing
Kai-Chi Chang, Tushar Sanjay Karnik, Chun-Ho Lee +9
Although thin-film lithium niobate (TFLN) facilitates efficient signal generation and nonlinear and quantum interactions, the realization of optical parametric amplification (OPA)…
Few-cycle electro-optic light on thin-film lithium niobate
Xinyi Ren, Chun-Ho Lee, Ian Christen +6
The twin fields of ultrafast optics and nonlinear photonics enable applications ranging from attosecond science [1, 2] and ultrafast electronics [3] to molecular spectroscopy [4, 5…
80 Channel Photon Pair Source from a Thin-Film Lithium Niobate Racetrack Microresonator
Mihir Chaudhari, Ian Christen, Xinyi Ren +6
Nanophotonic platforms have multiple properties and features desirable for producing correlated photon pairs. In these platforms, spontaneous parametric down-conversion (SPDC) and…
18-dB on-chip vacuum squeezing in an adaptively poled lithium niobate waveguide
Tushar Sanjay Karnik, Xinyi Ren, Chun-Ho Lee +16
Quantum squeezed states of light can enhance measurement sensitivity beyond classical limits and enable quantum information processing, but scalable low-loss sources remain challen…
Quantum squeezing in an all-resonant periodically poled lithium niobate microresonator
Xinyi Ren, Reshma Kopparapu, Tushar Sanjay Karnik +12
Quantum noise limits the sensitivity of optical measurements, but squeezed states of light enable quantum-enhanced metrology, sensing, and information processing. Most on-chip sque…
Suspended thin-film lithium niobate modulator for broadband mid-infrared light modulation and frequency comb generation
Chun-Ho Lee, Xinyi Ren, Xinzhou Su +12
The mid-infrared (MIR) spectral regime is central to applications including remote sensing, precision spectroscopy, higher harmonic generation, and free-space optical communication…
