Aberration sensing in fluorescence microscopy using quantum correlations
Shay Elmalem, Shaurya Aarav, Allard K. F. Hübler +2
Widefield fluorescence microscopy is an essential biological imaging tool, yet its penetration depth is fundamentally restricted by tissue-induced aberrations. Correcting these req…
Spatial coherence enabled sensorless adaptive optical imaging
Pranay Mohta, Shaurya Aarav, Hugo Defienne +1
Optical aberrations degrade imaging performance in label-free microscopy, where the absence of a guide star often necessitates sensorless adaptive optics (AO). Conventional sensorl…
Noise-Resilient Imaging through Coherence Filtering
Pranay Mohta, Keval Moliya, Aniket Nag +2
Noise is a significant challenge in imaging. Conventional intensity-based techniques mitigate noise through various filtering methods, but they often require prior knowledge of noi…
Super-resolution with Fourier measurements
S. A. Wadood, Shaurya Aarav, Kevin Liang +1
Resolving sources beyond the diffraction limit is important in imaging, communications, and metrology. Current image-based methods of super-resolution require phase information (ei…
Wavefront correction of high-dimensional two-photon states via coherence-entanglement transfer
Shaurya Aarav, Hugo Defienne
Reliable transmission of quantum optical states through real-world environments is key for quantum communication and imaging. Yet, aberrations and scattering in the propagation pat…
New scattering zones in quantum speckle propagation
Shaurya Aarav, S. A. Wadood, Jason W Fleischer
Quantum speckles exhibit significantly richer behavior than their classical counterparts due to their higher dimensionality. A simple example is the far-field speckle pattern in 1D…
Phase matching in -barium borate crystals for spontaneous parametric down-conversion
Suman Karan, Shaurya Aarav, Homanga Bharadhwaj +5
Spontaneous parametric down-conversion (SPDC) is the most widely used process for generating entangled photon pairs. In SPDC, a pump photon interacts with a nonlinear optical cryst…
Controlling propagation of spatial coherence for enhanced imaging through scattering media
Abhinandan Bhattacharjee, Shaurya Aarav, Harshawardhan Wanare +1
It is known that a spatially partially coherent light field produces better imaging contrast compared to a spatially coherent field and that the contrast increases as the spatial c…
Two-shot measurement of spatial coherence
Abhinandan Bhattacharjee, Shaurya Aarav, Anand K. Jha
We propose and demonstrate an interferometric scheme for measuring the two-dimensional two-point cross-spectral density function in a two-shot manner. Our scheme comprises a Michel…
Angular Schmidt spectrum of entangled photons: derivation of an exact formula and experimental characterization for non-collinear phase matching
Girish Kulkarni, Lavanya Taneja, Shaurya Aarav +1
We derive an exact formula for the angular Schmidt spectrum of the orbital angular momentum (OAM)-entangled states produced by parametric down-conversion (PDC). We show that our fo…
Efficient generation of propagation-invariant spatially-stationary partially coherent fields
Shaurya Aarav, Abhinandan Bhattacharjee, Harshawardhan Wanare +1
We propose and demonstrate a novel method for generating propagation-invariant spatially-stationary fields in a controllable manner. Our method relies on producing incoherent mixtu…
