摘要： The invention relates to an optical isolator of the type commonly employed in fiber-optic data transmission and amplifier systems. The optical isolator of the invention has a support (TR) which is provided with a recess (A). Two wedge-shaped plates (KP1, KP2) made of an optically birefringent material and a Faraday rotator (FR) are inserted in this recess (A). Preferably, the support (TR) is a silicon crystal in which a very precise recess (A) can be formed by wet-chemical etching. The individual components are passively adjusted in the recess by stops. The optical isolator of the invention therefore consists only of those components which are absolutely essential for its operation. Also provided is an advantageous wavelength multiplexer module with an integrated optical isolator. The construction of the wavelength multiplexer module is very simple and requires only two spherical lenses as imaging elements for three optical inputs/outputs.

摘要： The invention concerns a device whereby micro-optic parts, particularly those that tend to tilt because of their geometric dimensions, can be precisely arranged on a support. The device according to the invention comprises a support (TR) on which several guide elements (FE1 . . . FE4) are placed in cutouts (A1 l . . . A4). The arrangement of the guide elements (FE1 . . . FE4) is such that the micro-optic part (BT) to be positioned can be inserted between the guide elements (FE1 . . . FE4). In this way an active adjustment is not required. In a particularly advantageous embodiment of the invention, the guide elements (FE1 . . . FE4) touch the micro-optic part (BT) at points that are located at different distances from the surface of the support (TR). In this way tilting is prevented in a particularly effective manner. The support (TR) is made of a silicon substrate for example; the guide elements (FE1 . . . FE4) can be uncoated spherical lenses which are placed in cutouts etched into the substrate by means of wet chemical methods.
