Hello George, My questions are in regards to your statement: "I believe,based on what is disclosed to date, that LU will blow by SR so fast that they will think that LU is moving backwards" SR has stated that they can achieve 200 GBs per second now and LU says they will be able to do 40GBs per second for testing by late this year and commercially available in March 2000. Do you feel this time/speed differential is insignificant or that SR is not telling the truth? Is it not possible that LU is pre-announcing their single wave length technology to steal the thunder from other vendors(SR)with better technology?

They have disclosed nothing that effectively superimposes or multiplexes data optically because that isn't the data encoding procedure. Frank said we spend too much time trying to figure out how the technology works, but it is clear we haven't done enough. We must resolve the final piece of the puzzle, else you won't appreciate what SR has done. The idea is this: SR takes an input RF frequency and a carefully prepared beam which admits vast embedding and through a special diode allows the input RF to build high density channels in the beam stream. It is the density, the fineness of admission, which achieves the narrow linewidth and high throughput. The fineness of admission is achieved by the manufacture of Laguerre modes whose characteristics are amenable to the special attributes of refractive synchronization. The refractive mixing in the diode is where the action is. I quote from SR's white paper: As light is passed through an electro-optical crystal, optical modulation can be performed. The ability to change the refractive index abruptly and, therefore, the electric field, allows the signal to be modulated onto a light beam by a radio frequency (RF) signal applied to the electrodes on the crystal. This application of RF onto a light beam creates an amplitude modulation. The light beam then passes through two optical waveguide paths in the crystal at the frequency of the radio signal. Optical modulation is achieved, therefore, through the refraction of the optical signal. By combining the frequency spectrum of various sources and optically modulating each signal with a specific RF subcarrier frequency that has an appropriate sampling frequency and amplitude ratio, one can synchronize a number of different signals and coherently place them onto a single laser beam. This is Optical Refractive Synchronization. The refractive embedding requires that the beam can take the field density of input. This is the point of the Laguerre mode. It is a theoretical construct which attempts to explain why the embedding can take place at such densities and it is intimately connected with the equality of spin and orbital angular momentum of helical transverse motion of Pauli exclusion saturated photon orbits.
