  • Continuous high speed modulation of light with light
    Patent number: 4303309
    Abstract: Method and apparatus for the continuous high speed switching or modulation of light with light. A flow medium containing an active coupling medium is flowed relative to the light beams so as to continually restore the coupling medium which is degraded by interaction with the light beam, thereby maintaining the coupling medium in a desired condition for modulating a light beam. The problem of removal of heat generated by light power dissipation is eliminated by advective flow of the medium.
