Hyperbolic phonon-polariton electroluminescence in graphene-hBN van der Waals heterostructures
Qiushi Guo, Iliya Esin, Cheng Li +7
Phonon-polaritons are electromagnetic waves resulting from the coherent coupling of photons with optical phonons in polar dielectrics. Due to their exceptional ability to confine e…
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…
Enhancing Mobile Privacy and Security: A Face Skin Patch-Based Anti-Spoofing Approach
Qiushi Guo
As Facial Recognition System(FRS) is widely applied in areas such as access control and mobile payments due to its convenience and high accuracy. The security of facial recognition…
FaceSkin: A Privacy Preserving Facial skin patch Dataset for multi Attributes classification
Qiushi Guo, Shisha Liao
Human facial skin images contain abundant textural information that can serve as valuable features for attribute classification, such as age, race, and gender. Additionally, facial…
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…
