Journal ArticleDOI
TL;DR: In this paper, world-renowned artist David Hockney and University of Arizona optical sciences professor Charles Falco explain how their observation that certain Renaissance paintings seemed almost "photographic" in nature led them to launch an inquiry into the possibility of finding scientific evidence that some of the Old Masters relied on optical aids.
Abstract: In this feature, world-renowned artist David Hockney and University of Arizona optical sciences professor Charles Falco explain how Hockney's observation that certain Renaissance paintings seemed almost “photographic” in nature led them to launch an inquiry into the possibility of finding scientific evidence that some of the Old Masters relied on optical aids. Hockney's visual observations received scientific validation when application of basic optics principles to a number of Renaissance paintings began generating remarkably consistent results.

Journal ArticleDOI
TL;DR: An optical system capable of delivering independent 74 Mb/s streams to a very large number of users (>1000) using a technique with potentially low per-port costs is described.
Abstract: Growing demand for bandwidth at distributed locations, such as homes and small businesses, will require systems capable of delivering high bandwidths (>10 Mb/s) at affordable costs. Here, we describe an optical system capable of delivering independent 74 Mb/s streams to a very large number of users (>1000) using a technique with potentially low per-port costs.

Journal ArticleDOI
TL;DR: In this article, the authors developed new approaches to increase capacity and keep up with demand in undersea fiberoptic cables by developing new approaches for increasing capacity and keeping up demand.
Abstract: Undersea fiberoptic cables make international communications possible. The challenge is to develop new approaches to increase capacity and keep up with demand.





Journal ArticleDOI
TL;DR: Wave transmission is portrayed using line diagrams in which the amplitude is shown as a function of time and distance, but waves are characterized by their phase as well as their amplitude, and these drawings tell us nothing about the phase evolution.
Abstract: Historically, physicists and engineers have always portrayed wave transmission using line diagrams in which the amplitude is shown as a function of time and distance. This sort of drawing tells us what is happening to the wave amplitude. However, waves are characterized by their phase as well as their amplitude, and these drawings tell us nothing about the phase evolution. The advent of modern computers with color monitors and inexpensive color printers allows us to solve this problem in a visually appealing way by using a periodic color map to portray phase information. We can also portray information about the local frequency, the phase derivative with respect to time, using an aperiodic color map. We apply this approach to study light propagation in optical fibers.




Journal ArticleDOI
TL;DR: Dispersion managed solitons, now being developed by a number of different groups, can resolve the technical problems that in the past have prevented the use of the soliton transmission format in optical fiber communication systems.
Abstract: Dispersion managed solitons, now being developed by a number of different groups, can resolve the technical problems that in the past have prevented the use of the soliton transmission format in optical fiber communication systems. Given the rapid progress being made by researchers, within two years an Internet backbone powered by these inherently stable and robust nonlinear optical pulses will be a reality.
