Fiber Lens Based Optical Antenna Design for OWC With Full Beam Coverage
IEEE Photonics Journal, 2021 In infrared optical wireless communications, narrow beams require the perfect calibration of the base station (BS) and user terminal (UT), which cannot support multiple moving users. This paper proposes a fiber lens based optical antenna, which employs a

Effects of Anisotropic Turbulent Ocean on Propagation of Asymmetric Bessel-Gaussian Beam
IEEE Photonics JournalAiming at the propagation of asymmetric vortex beam, we investigate the spreading and wander characteristics of asymmetric Bessel-Gaussian beam in oceanic turbulence. Based on the cross-spectral density and Wigner distribution function of beam field, the
