  • Miniature optical fiber current sensor based on a graphene membrane, Laser Photonics Rev. 9, 517 (2015)

    Miniature optical fiber current sensor based on a graphene membrane, Laser Photonics Rev. 9, 517 (2015)

    The unique electronic and mechanical properties, of graphene make it an ideal material for nanoelectromechanical system (NEMS) applications. Here, a miniature optical fiber current sensor based on a quasistatic graphene NEMS with a graphene membrane covering the hole on a pre-etched fiber tip and two gold electrodes on opposite sides of the tip has been demonstrated.

  • Broadband tunable liquid crystal terahertz waveplates driven with porous graphene electrodes, Light Sci. Appl., 4, e253 (2015)

    Broadband tunable liquid crystal terahertz waveplates driven with porous graphene electrodes, Light Sci. Appl., 4, e253 (2015)

    Versatile devices, especially tunable ones, for terahertz imaging, sensing and high-speed communication, are in high demand. Liquid crystal based components are perfect candidates in the optical range; however, they encounter significant challenges in the terahertz band, particularly the lack of highly transparent electrodes and the drawbacks induced by a thick cell. Here, a strategy to overcome all these challenges is proposed: Few-layer porous graphene is employed as an electrode with a transmittance of more than 98%. A subwavelength metal wire grid is utilized as an integrated high-efficiency electrode and polarizer. The homogeneous alignment of a high-birefringence liquid crystal is implemented on both frail electrodes via a non-contact photo-alignment technique. A tunable terahertz waveplate is thus obtained. Its polarization evolution is directly demonstrated.

  • Nonlinear frequency conversion of fields with orbital angular momentum using quasi-phase-matching, Phys. Rev. A, 88, 063827 (2013)

    Nonlinear frequency conversion of fields with orbital angular momentum using quasi-phase-matching, Phys. Rev. A, 88, 063827 (2013)

    We propose and investigate the quasi-phase-matched (QPM) nonlinear optical frequency conversion of optical vortices in periodically poled lithium niobate. Laguerre-Gaussian (LG) modes are used to represent the orbital angular momentum (OAM) states, characterized with the azimuthal and radial indices. Typical three-wave nonlinear interactions among the involved OAM modes are studied with the help of coupling wave equations.

  • Tailoring entanglement through domain engineering in a lithium niobate waveguide, Scientific Reports 4,4812(2014)

    Tailoring entanglement through domain engineering in a lithium niobate waveguide, Scientific Reports 4,4812(2014)

    We propose to integrate the electro-optic (EO) tuning function into on-chip domain engineered lithium niobate (LN) waveguide. Due to the versatility of LN, both the spontaneously parametric down conversion (SPDC) and EO interaction could be realized simultaneously. Photon pairs are generated through SPDC, and the formation of entangled state is modulated by EO processes. An EO tunable polarization-entangled photon state is proposed. Orthogonally-polarized and parallel-polarized entanglements of photon pairs are instantly switchable by tuning the applied field.
