  • Ismail, Y; Barnes, G; Mhlanga, T; Belyi, V; Forbes, A (2010-03)
    In this paper the authors outline an optical design for producing high-order Bessel-like beams with a z-dependent cone angle through the use of conventional optical elements, without the need for deliberate aberrations to ...
  • Ismail, Y; Khilo, N; Belyi, V; Forbes, A (European Optical Society, 2012-09)
    We present a method for generating higher-order Bessel beams with z-dependent cone angles. Such fields, if engineered correctly, are shape invariant during propagation and thus do not suffer from a transition from a ...
  • Dudley, Angela L; Vasilyeu, R; Forbes, A; Khilo, N; Ropot, P; Belyi, V; Kazak, N (Society of Photo-Optical Instrumentation Engineers (SPIE), 2009-08)
    This paper presents a mechanism for the generation of the superposition of higher-order Bessel beams, which implements a ring slit aperture and spatial light modulator (SLM). The experimental technique is also adapted to ...
