ABSTRACT:
A light switch for controlling the transmission of optical energy through optical fibers includes a hollow, light-transmitting tube extending transversely across the end of at least one light transmitting fiber. The tube contains one or more masses of light diverting material in a matrix of light-transparent fluid. The masses of light diverting material may be reflective, refractive or absorbent. Means are provided for varying the pressure along the tube to shift the masses relative to the light transmitting fiber so as to divert or pass the light to receiving fibers.
