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…
Visible-to-mid-IR tunable frequency comb in nanophotonics
Arkadev Roy, Luis Ledezma, Luis Costa +6
Optical frequency comb is an enabling technology for a multitude of applications from metrology to ranging and communications. The tremendous progress in sources of optical frequen…
D-Flat: A Differentiable Flat-Optics Framework for End-to-End Metasurface Visual Sensor Design
Dean S. Hazineh, Soon Wei Daniel Lim, Zhujun Shi +3
Optical metasurfaces are planar substrates with custom-designed, nanoscale features that selectively modulate incident light with respect to direction, wavelength, and polarization…
Anisotropic diffraction induced by orbital angular momentum during propagations of optical beams
Guo Liang, Yuqing Wang, Qi Guo +1
It is demonstrated that the orbital angular momentum (OAM) carried by the elliptic beam without the phase-singularity can induce the anisotropic diffraction (AD). The quantitative…
Dirac-Point Solitons in Nonlinear Optical Lattices
Kang Xie, Qian Li, Allan D. Boardman +10
The discovery of a new type of solitons occuring in periodic systems without photonic bandgaps is reported. Solitons are nonlinear self-trapped wave packets. They have been extensi…
Transition between self-focusing and self-defocusing in nonlocally nonlinear media
Guo Liang, Weiyi Hong, Yahong Hu +7
We reveal the relevance between the nonlocality and the focusing/defocusing states in nonlocally nonlinear media, and predict a novel phenomenon that the self-focusing/self-defocus…
