Broadening the high sensitivity range of squeezing-assisted interferometers by means of two-channel detection
Gaurav Shukla, Dariya Salykina, Gaetano Frascella +3
For a squeezing-enhanced SU(2) interferometer, we theoretically investigate the possibility to broaden the phase range of sub-shot-noise sensitivity. We show that this goal can be…
Reconstructing 2D spatial modes for classical and quantum light
Valentin A. Averchenko, Gaetano Frascella, Mahmoud Kalash +2
We propose a method for finding 2D spatial modes of thermal field through a direct measurement of the field intensity and an offline analysis of its spatial fluctuations. Using thi…
Spontaneous Parametric Down-Conversion from Subwavelength Nonlinear Films
Tomás Santiago-Cruz, Vitaliy Sultanov, Haizhong Zhang +2
Miniaturised entangled photon sources are highly demanded for the development of integrated quantum photonics. Since the invention of subwavelength optical metasurfaces and their s…
Optical Coherence Tomography with a nonlinear interferometer in the high parametric gain regime
Gerard J. Machado, Gaetano Frascella, Juan P. Torres +1
We demonstrate optical coherence tomography based on an SU(1,1) nonlinear interferometer with high-gain parametric down-conversion. For imaging and sensing applications, this schem…
Overcoming detection loss and noise in squeezing-based optical sensing
Gaetano Frascella, Sascha Agne, Farid Ya. Khalili +1
Among the known resources of quantum metrology, one of the most practical and efficient is squeezing. Squeezed states of atoms and light improve the sensing of the phase, magnetic…
Pump depletion in parametric down-conversion with low pump energies
Jefferson Flórez, Jeff S. Lundeen, Maria V. Chekhova
We report the efficient generation of high-gain parametric down-conversion, including pump depletion, with pump powers as low as 100 W (energies ~J/pulse) and conversion…
