  Año 2005, Número 12

  • The History of OSA The launch of JOSA A: Optics and Imaging Science

    J. N. Howard

    págs. 12-13

    

  • All Optical Control: Investigators have long sought ways to control optical systems without needing to convert from optical to electrical signals. Here we highlight three examples of optical control

    págs. 15-17

    

  • Biophotonics: Optical manipulation is being used to study biophysical interactions. Optical constraining forces allow a single cell to be held and measured spectroscopically

    págs. 18-20

    

  • Cooling and Trapping: Cooling and trapping of atoms and molecules have allowed researchers to construct new materials and explore physical extremes

    págs. 21-22

    

  • Imaging: Frontiers in imaging this year include a new model to explain scaling laws in vision, the use of 47 nm ultraviolet light to image with nanometer resolution, and the use of Raman-scattered light for molecular imaging

    págs. 23-25

    

  • Lasers: Modern optics began in 1960 with the first laser. We're still seeing new contributions such as increased output power of highly coherent sources and lasers that operate at shorter wavelengths

    págs. 26-27

    

  • Nonlinear Optics: New material properties and metrology are improving the utility of nonlinear optics. By gaining a better understanding of the interactions at surfaces, researchers can expand the wavelengths available to spectroscopy and microscopy

    págs. 28-31

    

  • Optical Engineering: Sometimes optics is interesting because of its novelty and wide-anging applications. This year's submissions span an extraordinary breadth of topics

    págs. 32-33

    

  • Optical Switching: One of our summaries emphasizes switching of an optical signal at low light levels while the second focuses on switching speed

    págs. 34-35

    

  • Photonic Structures: Fifteen years ago, photonic structures were available only in the microwave wavelength region. Now we can construct structures with textbook quality Brillouin zones and optically control the optical properties of the structures

    págs. 36-39

    

  • Quantum Information: Secure communications is at the heart of quantum information technology. Here a near-term method of encryption is described as a step toward becoming able to transfer qubits from photons to other quantum systems

    págs. 40-41

    

  • Slow Light: We highlight an interesting application of slow light to modern communication technology

    pág. 42

    

  • Solitons: Solitons continue to excite theoretical interest, and researchers are probing their interactions experimentally
