Published in 2021 at "Optics Communications"

DOI: 10.1016/j.optcom.2021.126964

Abstract: Abstract A mode selective comb filter based on the Mach–Zehnder interferometer (MZI) is proposed and theoretically analyzed. The proposed filter consists of two vector mode selective couplers (MSCs). The vector MSCs are used to convert… read more here.

Published in 2019 at "Scientific Reports"

DOI: 10.1038/s41598-019-53914-8

Abstract: We experimentally study a nonlinear optical approach to selective manipulation and detection of structured images mixed with turbulent noise. Unlike any existing adaptive-optics method by applying compensating modulation directly on the images, here we account… read more here.

Published in 2019 at "IEEE Journal of Quantum Electronics"

DOI: 10.1109/jqe.2019.2940711

Abstract: In order to improve channel capacity of a communication system, a novel concept of all-fiber cylindrical vector beams (CVB) multiplexing through a mode-selective coupler (MSC) is proposed. According to the proposed concept, a step-index few-mode… read more here.

Published in 2017 at "Optics express"

DOI: 10.1364/oe.25.004493

Abstract: We experimentally demonstrate on-chip mode-selective wavelength conversions based on the degenerate four-wave mixing (FWM) nonlinear effect in a few-mode silicon waveguide. A multimode waveguide with tapered directional coupler based mode (de)multiplexers is designed and fabricated.… read more here.

Published in 2018 at "Optics express"

DOI: 10.1364/oe.26.019171

Abstract: We experimentally investigate high-order modes (HOMs) generating at the wavelength of 1.0 μm in all-fiber Yb-doped lasers based on mode-selective couplers (MSCs). Broadband MSCs for HOMs conversion are achieved by optimizing the phase-matching condition at… read more here.

Published in 2022 at "Optics express"

DOI: 10.1364/oe.463398

Abstract: A multi-channel orbital angular momentum (OAM) mode generation and switching scheme is proposed and demonstrated based on an in-fiber mode selective interferometer (MSI), which is formed in a four-mode fiber. The MSI consists of two… read more here.

Published in 2021 at "Photonics Research"

DOI: 10.1364/prj.411529

Abstract: Non-mode-selective (NMS) multiplexers (muxes) are highly desirable for coherent power combining to produce a high-power beam with a shaped profile (wavefront synthesis) from discrete, phase-locked emitters. We propose a design for a multi-plane light conversion… read more here.

Published in 2019 at "Progress In Electromagnetics Research Letters"

DOI: 10.2528/pierl19051506

Abstract: As one of the important means in discriminating every mode in a high power microwave (HPM) multimode system, utilizing a mode-selective directional coupler to quantitatively analyze multimodes and power measurement has been proposed. The first… read more here.
