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…
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…
Measurement of pure states of light in the orbital-angular-momentum basis using nine multipixel image acquisitions
Girish Kulkarni, Suman Karan, Anand K. Jha
The existing techniques for measuring high-dimensional pure states of light in the orbital angular momentum (OAM) basis either involve a large number of single-pixel data acquisiti…
