Published in 2018 at "Optics and Lasers in Engineering"

DOI: 10.1016/j.optlaseng.2018.01.012

Abstract: Abstract We propose a new scheme to encrypt multiple images simultaneously using two-dimensional binary phase masks. Each of the original greyscale images is first decomposed into two pure phase-only images, which corresponds to the reverse… read more here.

Published in 2020 at "Ultrasonics"

DOI: 10.1016/j.ultras.2020.106270

Abstract: Thanks to their low cost, compactness and suitability of use in industrial environments, CW lasers represent a viable alternative to more traditional pulsed lasers for non-contact inspection of structures, both under static and working conditions.… read more here.

Published in 2017 at "IEEE Communications Letters"

DOI: 10.1109/lcomm.2017.2654442

Abstract: A physical layer encryption method is proposed for orthogonal frequency division multiplexing with offset quadrature amplitude modulation. The proposed method uses intentionally added pure imaginary symbols as keys, so that their intrinsic interferences can obfuscate… read more here.

Published in 2019 at "Journal of Nanophotonics"

DOI: 10.1117/1.jnp.13.016007

Abstract: Abstract. A cost-efficient multimode interference-based sensor with corroded polarization-maintaining fiber (PMF) is proposed and experimentally demonstrated for the measurement of liquid refractive index (RI) and temperature. The sensor consists of a segment of corroded PMF… read more here.

Published in 2022 at "Applied optics"

DOI: 10.1364/ao.458385

Abstract: The security strength of an interference-based optical image cryptosystem with a designed amplitude modulator (AM) is evaluated. Compared to previous improved interference-based cryptosystems in which iterative or post-processing algorithms are involved, to remove the silhouette… read more here.

Published in 2017 at "Optics express"

DOI: 10.1364/oe.25.017174

Abstract: The ability to localize precisely a single optical emitter is important for particle tracking applications and super resolution microscopy. It is known that for a traditional microscope the ability to localize such an emitter is… read more here.

Published in 2022 at "Optics express"

DOI: 10.1364/oe.458881

Abstract: In this paper, we propose a comprehensive quantum theoretical framework to formulate the quantum interference inside the parity-time (PT) symmetric waveguide system which is formed by two coupled optical waveguides with unequal losses. Based on… read more here.
