Classical-to-quantum transfer of geometric phase for non-interferometric phase measurement and manipulation of quantum state
Vimlesh Kumar, Chahat Kaushik, M. Ebrahim-Zadeh +2
The geometric phase, originating from the cyclic evolution of a state, such as polarization on the Poincaré sphere, is typically measured through interferometric approaches that of…
Device-independent, megabit-rate quantum random number generator with beam-splitter-free architecture and live Bell test certification
Ayan Kumar Nai, Vimlesh Kumar, M. Ebrahim-Zadeh +1
Device-independent quantum random number generators (DI-QRNGs) are crucial for information processing, ensuring certified quantumness and genuine randomness. However, existing impl…
Mean-field equation for phase-modulated optical parametric oscillator
A. D. Sanchez, S. Chaitanya Kumar, M. Ebrahim-Zadeh
The widely established techniques for the generation of ultrashort optical pulses rely on passive mode-locking of lasers, with the output pulse duration and emission spectrum deter…
Quadratic frequency comb based on phase-modulated cw-driven optical parametric oscillator with intracavity dispersion control
A. D. Sanchez, S. Chaitanya Kumar, M. Ebrahim-Zadeh
We report a novel configuration of bulk optical parametric oscillator (OPO) capable of delivering coherent broadband phase-locked spectrum when driven by a continuous-wav…
CUDA-based focused Gaussian beams second-harmonic generation efficiency calculator
A. D. Sanchez, S. Chaitanya Kumar, M. Ebrahim-Zadeh
We present an object-oriented programming (OOP) CUDA-based package for fast and accurate simulation of second-harmonic generation (SHG) efficiency using focused Gaussian beams. The…
CUDA-based optical parametric oscillator simulator
Alfredo Daniel Sanchez, Chaitanya Kumar Suddapalli, Majid Ebrahim-Zadeh
The coupled-wave equations (CWEs) in nonlinear optics are the fundamental starting point in the study, analysis, and understanding of various frequency conversion processes in diel…
Talbot effect-based sensor measuring grating period change in subwavelength range
Saumya J. Sarkar, M. Ebrahim-Zadeh, G. K. Samanta
Talbot length, the distance between two consecutive self-image planes along the propagation axis for a periodic diffraction object (grating) illuminated by a plane wave, depends on…
Imaging inspired characterization of single photons carrying orbital angular momentum
Vimlesh Kumar, Varun Sharma, Sandeep Singh +4
We report on an imaging-inspired measurement of orbital angular momentum (OAM) using only a simple tilted lens and an Intensified Charged Coupled Device (ICCD) camera, allowing us…
SHG (532 nm)-induced spontaneous parametric downconversion noise in 1064 nm-pumped IR upconversion detectors
L. Meng, A. Padhye, C. Pedersen +2
As a novel technique for infrared detection, frequency upconversion has been successfully deployed in many applications. However, investigations into the noise properties of upconv…
Few-cycle, Broadband, Mid-infrared Optical Parametric Oscillator Pumped by a 20-fs Ti:sapphire Laser
Suddapalli Chaitanya Kumar, Adolfo Esteban-Martin, Takuro Ideguchi +5
We report a few-cycle, broadband, singly-resonant optical parametric oscillator (OPO) for the mid-infrared based on MgO-doped periodically-poled LiNbO3 (MgO:PPLN), synchronously pu…
