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…
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…
