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…
Non-monotonic dependence of OAM Schmidt spectrum on crystal thickness
Harshal Jain, Suman Karan, Radhika Prasad +1
The orbital angular momentum (OAM) of photons provides a high-dimensional resource for quantum information protocols. The dimensionality of OAM-entangled states generated via spont…
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…
OAM-mode sorting with a wavefront twister
Suman Karan, Swati Chaudhary, Harshwardhan Wanare +1
We propose an OAM sorter based on a novel optical element that we refer to as a wavefront twister. It is a generalization of the conventional wavefront rotators such as the Dove pr…
Polarization-preserving wavefront rotator
Suman Karan, Aman Srivastava, Pratham Sachin Todkar +1
A K-mirror rotates the wavefront of an incident optical field. However, the rotation always introduces polarization changes in the transmitted field. This is a serious concern for…
An experimental technique for measuring radial coherence
Radhika Prasad, Nilakshi Senapati, Suman Karan +4
Coherence refers to correlations between field vibrations at two separate points in degrees of freedom such as space, time, and polarisation. In the context of space, coherence the…
A wavefront rotator with near-zero mean polarization change
Suman Karan, Nilakshi Senapati, Anand K. Jha
A K-mirror is a device that rotates the wavefront of an incident optical field. It has recently gained prominence over Dove prism, another commonly used wavefront rotator, due to t…
