Autocompensating high-dimensional quantum cryptography by phase conjugation in optical fibers [PDF]

EPJ Web of Conferences, 2020
We present a system based on phase conjugation in optical fibers for autocompensating highdimensional quantum cryptohraphy. Phase changes and coupling effects are auto-compensated by a single loop between Alice and Bob.

Functionalized silver nanoparticles as an effective medium towards trace determination of arsenic (III) in aqueous solution

Results in Physics, 2019
Arsenic is well known for its toxicity and various health effects. In this work, we report a simple, environment friendly and cost effective colorimetric approach for selective detection of arsenic (III) in aqueous medium.

Kinoform optics applied to X-ray photon correlation spectroscopy

Journal of Synchrotron Radiation, 2010
Moderate-demagnification higher-order silicon kinoform focusing lenses have been fabricated to facilitate small-angle X-ray photon correlation spectroscopy (XPCS) experiments. The geometric properties of such lenses, their focusing performance and their applicability for XPCS measurements are described.

Diamond photonics platform enabled by femtosecond laser writing [PDF]

, 2016
We demonstrate the first buried optical waveguides in diamond using focused femtosecond laser pulses. The properties of nitrogen vacancy centers are preserved in the waveguides, making them promising for diamond-based magnetometers or quantum information
