摘要： 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.

摘要： A planar waveguide lens is characterized in that the same is a gradient lens, whereby the refractive index profile transversely to the lens axis extends approximately parabolically. The lens may be constructed to be multi-mode or may be constructed to be single-mode in the spatial direction perpendicular to the lens axis and perpendicular to the axis in which the indicated change of the refractive index profile extends. Grid structures are provided for dividing the light. The grid structures may be permanent, electro-optically produced or acousto-optically produced. For single mode fibers, the grid structures are produced by acoustic surface waves, while for multi-mode fibers, the grid structures are produced by way of acoustical volume waves.

The guide body of each channel is preferably produced by a series of production steps while in a flat state either by mechanically forming the grooves, depositing material to form the grooves or developing a layer of material by a photolithographic process. Subsequent to forming the grooves, the guide body may be wound and secured on a cylindrical substrate so that the channels are disposed on a curved surface. The device may have a single holder to form a non-detachable connecting device, a pair of holders which are secured in an aligned position and form a detachable coupling device or a pair of holders mounted for relative rotation to form an optical switch.

摘要： A prism coupler for coupling light into and out of an optical waveguide and characterized by the temperature dependency being eliminated. This is accomplished by a skillful selection of the prism angle and the prism material of a single prism or by combining two prisms of different materials whose indices of refraction and prism angles are selected to compensate for the effects of temperature on both the prism and the waveguide. Preferably, the waveguide is doped in a substrate of LiNbO.sub.3 and the prism utilizes a compound prism having a first prism consisting of LiNbO.sub.3 and a second prism of polystyrene.
