"ultrafast laser pulses equipped with optical transistors in free space and optical fiber. The laser light travels through optical fiber no loss low noise level... 2 laser beams transmitted from 2 sources passing through same glass. 1 constant, transmission controlled 2nd beam. By using 2nd to shift properties transparent to reflective start and stop transmission of constant beam, switching signal on to off and back again quickly... 1st sep transmitting data 1 million times faster, few hundred attoseconds... speed up transfer rate billionfold"
