Abstract: A light deflector includes a plurality of individual acousto-optical light waveguide deflectors being integrated on a common substrate and disposed relative to one or more directions from which or to which a light beam to be deflected will be supplied so that the resolved points is equal to the sum of the resolved points of each of the individual deflectors. Preferably, the individual light deflectors are disposed and aligned on the substrate so that the deflection ranges of the resolved points lie next to one another in a prescribed surface and with the ranges contacting one another without gaps.

Abstract: An optical device, such as the switch, for controlling the passage of a light beam into and out of an end face of a waveguide such as a glass fiber includes utilizing either a layer or drop of liquid material to control the light passage. The liquid material can be a layer, which has changeable optical properties, which can occur by applying a magnetic field, heat or electrical field or the material can be a layer of electrolyte material which will precipitate a reflective layer or electrochromic layer in response to an application of an electrical field. In another embodiment, the liquid material may be moved into and out of engagement with the end face to change the reflective nature of the end face and to cause decoupling of light from the end face or block the transmission of light.

Abstract: A device for coupling an incoming light conducting fiber cable to an outgoing light conducting fiber cable characterized by at least one housing and means secured in the housing for holding the end faces of the light conducting fibers of each cable in centered relationship to each other and for optically interconnecting the ends faces of the light conducting fibers of the incoming cable to the end faces of the light conducting fibers of the outgoing cable. The means includes at least one holder having a guide body with guide channels for the light conducting fibers extending inward from one surface of the body and a cover member disposed on the guide body to close off the guide channels so that the light guiding fibers disposed in the channels are held therein.

Abstract: A device for coupling an incoming light conducting fiber cable to an outgoing light conducting fiber cable characterized by a pair of housings connected together and each receiving a holder which holders center the fibers in one cable in relation to the fibers of the cable which is centered by the other holder. The improvement comprises the holder includes a substrate having a first guide foil disposed on one surface and a second guide foil disposed on the opposite surface, each of said foils having aligned channels for receiving light conducting fibers with the channels of the first foil in a direction leading away from the substrate possessing a cross-sectional profile, decreasing to the diameter of the light conducting fibers.
