  • Optical methods for distance and displacement measurements

    Berkovic, Garry; Shafir, Ehud
    • 2012
    • Advances in Optics and Photonics 4(4) 441-471  View: HTML | PDF

    This tutorial reviews various noncontact optical sensing techniques that can be used to measure distances to objects, and related parameters such as displacements, surface profiles, velocities and vib...

  • High-contrast gratings for integrated optoelectronics

    Chang-Hasnain, Connie J.; Yang, Weijian
    • 2012
    • Advances in Optics and Photonics 4(3) 379-440  View: HTML | PDF

    A new class of planar optics has emerged using subwavelength gratings with a large refractive index contrast, herein referred to as high-contrast gratings (HCGs). This seemingly simple structure lends...

  • Wigner functions in optics: describing beams as ray bundles and pulses as particle ensembles

    Alonso, Miguel A.
    • 2011
    • Advances in Optics and Photonics 3(4) 272-365  View: HTML | PDF [Suppl. Mat. (30)]

    This tutorial gives an overview of the use of the Wigner function as a tool for modeling optical field propagation. Particular emphasis is placed on the spatial propagati...

  • Polarization-resolved nonlinear microscopy: application to structural molecular and biological imaging

    Brasselet, Sophie
    • 2011
    • Advances in Optics and Photonics 3(3) 205-  View: HTML | PDF

    In this tutorial I analyze the polarization-dependent properties of different optical contrasts widely used today in imaging, applied to biology and biomedical diagnostics. I derive the essential prop...

  • Structured-light 3D surface imaging: a┬átutorial

    Geng, Jason
    • 2011
    • Advances in Optics and Photonics 3(2) 128-160  View: HTML | PDF [Suppl. Mat. (1)]

    We provide a review of recent advances in 3D surface imaging technologies. We focus particularly on noncontact 3D surface measurement techniques based on structured illum...

  • Angular dispersion: an enabling tool in nonlinear and quantum optics

    Torres, Juan P.; Hendrych, Martin; Valencia, Alejandra
    • 2010
    • Advances in Optics and Photonics 2(3) 319-369  View: HTML | PDF

    The dispersive properties of materials, i.e., their frequency-dependent response to the interaction with light, in most situations determines whether an optical process c...

  • Slow light in various media: a tutorial

    Khurgin, Jacob B.
    • 2010
    • Advances in Optics and Photonics 2(3) 287-318  View: HTML | PDF

    I consider the physical basics of slow light propagation in atomic media, photonic structures, and optical fibers. I show similarities and differences between all of the ...

  • Optical image compression and encryption methods

    Alfalou, A.; Brosseau, C.
    • 2009
    • Advances in Optics and Photonics 1(3) 589-636  View: HTML | PDF

    Over the years extensive studies have been carried out to apply coherent optics methods in real-time communications and image transmission. This is especially true when a...

  • Optical Antennas

    Bharadwaj, Palash; Deutsch, Bradley; Novotny, Lukas
    • 2009
    • Advances in Optics and Photonics 1(3) 438-483  View: HTML | PDF

    Optical antennas are an emerging concept in physical optics. Similar to radiowave and microwave antennas, their purpose is to convert the energy of free propagating radia...

  • Understanding leaky modes: slab waveguide revisited

    Hu, Jonathan; Menyuk, Curtis R.
    • 2009
    • Advances in Optics and Photonics 1(1) 58-106  View: HTML | PDF [Suppl. Mat. (8)]

    Computational methods for determining the complex propagation constants of leaky waveguide modes have become so powerful and so readily available that it is possible to use these methods with little u...
