Thread,
I received an email from Robert Dahlgren, Chairman of the Santa Clara Valley Chapter of the IEEE Lasers & Electro-Optics Society. Bob was kind enough to include in his message the following notice which was put out by the Society, concerning a presentation that SilkRoad's Dr. Palmer will be giving next month (September 28th).

Optical Refractive Synchronization Coherent Information In A Waveguide
Dr. James R. Palmer (SilkRoad, Inc., San Diego, Ca. U.S.A)
Abstract
I am going to introduce this paper by beginning with a definition of Optical Refractive Synchronization. Fundamentally, the process of refraction is the change of energy, direction or speed of a light beam that is propagating through a medium. In the one case, the change in direction is a continuous bending of the light beam and the subsequent change of speed of the light in the medium that is referred to as the index of refraction of the material. In the second case, there is the abrupt change in the index, polarity or phase of the medium that directs the energy out of the medium, or changes the ability of the light to pass through the medium, thereby absorbing the energy.
The second case is the technique employed in Optical Refractive Synchronization. The light is passed through a crystal which has the refractive index changed abruptly, and subsequently the electric field, by mixing a radio frequency signal into the crystal which then creates a modulation on to the wavelength of light passing through, or absorbing, in the crystal at the frequency of the radio signal that is to be modulated onto the light beam.
This Optical Modulation is performed, therefore, through the application of the refraction of the optical signal. Unlike the conventional wisdom, in my formulation, the x and y components of the electromagnetic wave vectors are not independent of space and, most importantly, are not independent of time. In order for Optical Refractive Synchronization to work, space and time must both be dealt with in all three orthogonal dimensions. As I progress through the analysis, it will become apparent to the reader that we are dealing with five (5) dimensions with the addition of time. Maxwell's field equations describe the coupling between the electric and magnetic field vectors and their interaction with matter in space and time. For the most part, I will use as my initial basis, the work of Born and Wolf dealing with the propagation of light in anisotropic crystals.
Most especially, I will deal with polarized waves where we find that, " . . in an anisotropic medium the energy is in general propagated with a different velocity and in a direction different from that of the wave normal.” To add insult to injury, I will also avail myself of the fine work of Richard Beth and many of those scholars that followed his work in the development and measurement of angular momentum of photons. For the most part, this is a function of azimuthal position symmetric to a circular axis providing a distribution of electric field, or magnetic field energy relative to the distance from the “z” axis to the outer radius in a waveguide.
This paper, then, will introduce the characteristic equations that describe going from a two dimensional radio frequency world into a five dimension plus time optical world. At the end of the day, however, the reader will grasp that by using optical constants for various materials that the two worlds can be readily resolved into the continuation from one to the other without discontinuity.
Obviously, this will require a different perspective on the two worlds. However, it is my intent to integrate these two worlds into one mathematical technique that will be fungible in whatever world one finds themselves.

Biography
J. R. Palmer is presently the Chief Technical Officer of SilkRoad, Inc. He was previously an adjunct Senior Research Scientist at the University of Alabama, Center For Applied Optics in Huntsville, Alabama. Dr. Palmer was most recently the Department Chairman of The Electronics Department at The Career College Of Northern Nevada and has just recently returned from a year and a half in Europe while teaching at Trinity College-Dublin in the schools of Physics and Law. He was formerly the Chief Scientist of Comarco, Inc. Prior to that he was a Senior Staff Consultant to TRW, Redondo Beach, California. He has had his own consulting company for twenty years. In 1984 he was awarded the Rudolf Kingslake Medal and Prize by The International Society For Optical Engineering (SPIE). He has published more than one hundred and fifty articles relating to transient thermodynamics in coatings, optics, and optical systems. At present, he has just finished re-writing the second edition of High Power Laser Optics for Pro Se Publishing. A second book entitled, Transient Heat Transfer In Flat Plates - Vol I - Conduction In Solids has just been published by Pro Se Publishing Co. This is the first volume in a multi-volume effort.
He received his B. S. Ch. E. and M. S. Ch. E. from California State University, Long Beach, PhD. in Chemical Physics from the University of California, Los Angeles, and a Juris Doctor in Law from Western State University Law School in San Diego. He is a member of Sigma Xi, Sigma Theta Phi, SPIE, AIP, AAAS, New York Academy of Sciences, OSA, and is a biographee in the 20th edition of Who's Who In The West, the first edition of International Who's Who in Optical Science and Engineering, Who's Who In America, Who's Who In The World Of Finance And Industry, and Who's Who In The World. |
