Broadband photon pairs are highly desirable for quantum metrology, quantum sensing, and
quantum communication. Such sources are usually designed through type-0 phase …

In this Letter, we report a first experimental realization of bright ultra-broadband (180 THz)
fiber-based biphoton source with widely spectrally separated signal and idler photons. Such …

The generation of interband photon pairs with wavelengths near 0.5 and 1.6 μm in a
photonic-crystal fiber under low-power cw optical pumping by a diode laser with a central …

Broadband correlated photon pairs (biphotons) are valuable in quantum metrology, but
current generation methods either involve complex nonlinear structures or lack sufficient …

Several consequences of the tangle model go beyond quantum field theory. Classifying the
possible rational tangles yields the spectrum of elementary particles, their quantum …

Numerical modeling and analysis of dispersion characteristics of a lithium niobate
nanowaveguide with an inversely inclined trapezoidal cross-sectional structure have been …

The wavefunction of a broadband biphoton field arising in parametric down-conversion in an
aperiodically polarized nonlinear crystal with a linear chirp under the action of a short pump …
