Photonic integrated processor for structured light detection and distinction
Johannes Bütow, Varun Sharma, Dorian Brandmüller +2
Integrated photonic devices have become pivotal elements across most research fields that involve light-based applications. A particularly versatile category of this technology are…
Near-video frame rate quantum sensing using Hong-Ou-Mandel interferometry
Sandeep Singh, Vimlesh Kumar, Varun Sharma +2
Hong-Ou-Mandel (HOM) interference, the bunching of two indistinguishable photons on a balanced beam-splitter, has emerged as a promising tool for quantum sensing. There is a need f…
Generating free-space structured light with programmable integrated photonics
Johannes Bütow, Jörg S. Eismann, Varun Sharma +2
Structured light is a key component of many modern applications, ranging from superresolution microscopy to imaging, sensing, and quantum information processing. As the utilization…
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…
High-power, continuous-wave, tunable mid-IR, higher-order vortex beam optical parametric oscillator
A. Aadhi, Varun Sharma, G. K. Samanta
We report on a novel experimental scheme to generate continuous-wave (cw), high power, and higher-order optical vortices tunable across mid-IR wavelength range. Using cw, two-cryst…
