Abstract: A fiber optic amplifier is disclosed, comprising a fiber optic, monomode waveguide (20) having a core (64) and cladding (66). A portion (70) of the cladding (66) over a predetermined region is removed and replaced by an active medium (30) capable of absorbing light energy at a first wavelength and emitting light energy at a second wavelength. The active medium (30) is a lasing dye that has an index of refraction adjusted to be slightly less than the index of refraction of the fiber core (64). The amount of cladding (66) removed is adjusted such that a predetermined amount of penetration of the evanescent field from a pump light signal (36) coupled into an end of the fiber (20) penetrates the active medium (30). A probe signal (38) to be amplified causes stimulated emission from the excited dye molecules by penetration of its evanescent field into the dye (30) in the region where the cladding is removed.In the preferred embodiment a recirculating pump (110) is used to circulate dye (30) through a cavity (112) placed over the fiber (20) where the cladding portion (70) is removed. The dye molecules in contact with the surface (72) formed by removal of the cladding (66) are continually changed. A temperature control unit (110) maintains the temperature of the dye (30) such that its index of refraction remains tuned to an amount just less than the index of refraction of the core (64).

Abstract: Bidirectional communication of voice analog and data message signals over a two wire telephone line (16) that inter-connects several electronic key telephone station sets (18) with a digital access circuit (13) of a central data and voice communication facility (19) is achieved by a multiplexing circuit that functions either as a set interface (17) for a telephone or as a line card interface (11) for the access circuit (13). Data messages originating at a key pad (52) of any set or which are input to an interface bus of the multiplexing circuit are stored in a shift register (23) for subsequent modulation of a high band carrier signal, but only one interface (11) (17) may enter a transmission mode at one time. Transmission priority is therefore assigned by a controller (25) to the interface (11) (17) that first attempts transmission on an inactive line (16), i.e., in the absence of the carrier signal. With transmission initiated, all other interfaces (11) (17) enter a monitor mode to listen but not act on the transmitted message. Errors in transmissions caused by line noise, or collision transmissions between two or more interfaces (11) (17) are resolved via message transactions between the interfaces. Retransmission priority based on the unique addresses of the calling interfaces (11) (17) resolves collision issues with priority going to the lowest address. Controllable transmit and receive equalizers (36') (37') define analog signal paths in the line card interface (11) and are always in an operational mode. Corresponding equalizers (36) (37) in the set interface (17) are normally quiescent and become fully operational only after a correct address match between calling and called interfaces (11) (17) occurs and the called interface responds with a line signal acknowledging receipt of a valid message. A codec (20) may then be enabled and bidirectional communication between a set (18) and the facility (19) is established with voice and signalling being frequency division multiplexed on the line (16).

Abstract: A node of an optical transmission network, for example a local area network, has a combined by-pass switch and optical modulator. The by-pass switch and modulator (45) comprises an optical switching matrix with two non-intersecting waveguides (W1, W2) connected by a further waveguide (W3). The junctions between the non-intersecting waveguides and the further waveguide perform both modulation of an optical carrier signal and re-routeing of the transmission path along the network.

Abstract: A gas distributor beam includes a plenum and distribution slot surrounded by a generally V-shaped cooling fluid chamber. The circulation of a suitable cooling fluid tends to maintain the plenum and distribution slot at a temperature below four hundred degrees Fahrenheit for the distribution of diborane gas to an upper surface of a heated glass ribbon. Carbon blocks are utilized to stabilize the glass temperature above nine hundred fifty degrees Fahrenheit for the proper deposition of boron on the surface of the glass. Insulation between the carbon blocks and the outer walls of the cooling fluid chamber minimize heat transfer and the shape of the cooling chamber minimizes the exposure of the glass to the lower temperatures of the cooling chamber.

Abstract: A converter has an invertor arrangement which is furnished with power semiconductor components. In the event of high voltages in the DC intermediate circuit, the rated voltage and the rated insulation voltage of the power semiconductor components in the invertor arrangement must be taken into account. Conventionally, the invertor arrangement was furnished with power semiconductor components whose rated voltage and rated insulation voltage exceeded the voltage in the DC intermediate circuit. In order to be able to use semiconductor components with lower rated voltages and rated insulation voltages, that is to say, in particular, cheaper components, the invention proposes connecting a plurality of invertors in series, that is to say in cascade, so that only a proportion of the overall DC voltage is applied to each partial intermediate circuit produced in this way, so that the power semiconductor components in each invertor can be components with a low rated voltage and rated insulation voltage. The invertors are regulated by a regulator device such that the voltage breakdown is equal within the invertor cascade. Controlled resistor arrangements are provided on the individual invertors or the invertors which are connected in groups, to protect against the voltage surges which occur briefly in the event of disturbances in the system. <IMAGE>
