WebOptics Letters December 1, 2012 We demonstrate partial conversion of circularly polarized light into orbital angular momentum-carrying vortex light with opposite-handed circular polarization. This conversion is accomplished in a novel manner using the birefringent properties of a circular subwavelength slit in a thin metal film. Our technique ... WebAbout us. We unlock the potential of millions of people worldwide. Our assessments, publications and research spread knowledge, spark enquiry and aid understanding around the world.

Web1 Sep 2004 · A subwavelength aperture is a key element in near-field optical devices and many recent photonic structures. When the lateral dimensions of such aperture is smaller than half the wavelength, light cannot propagate through the hole and the transmission is typically very weak. It is usually believed to scale as the fourth power of the aperture ... Web1 Aug 2003 · This could lead to miniaturized photonic circuits with length scales that are much smaller than those currently achieved. Surface plasmons are being explored for their potential in subwavelength optics, data storage, light generation, microscopy and bio-photonics.
