摘要： An optically bistable device 100 is disclosed having a self electro-optic effect device (SEED) 104 and a variable optical attenuator 103 for maintaining the state of the SEED over a wide power range of two input light beams. The SEED is responsive to the relative power levels of the two input light beams for assuming one of two states. The state of the SEED is determined by the transmission level of one of the beams passing through quantum well region 102 of the device. The variable optical attenuator concomitantly varies the power level of the two input beams to maintain the present state of the SEED over a wide range of input light beam powers. When operated in a bistable operating region of the device, a control light beam with a low power level changes the device from one state to another. Two threshold values of a ratio of power between the two input beams establish where the device switches from one state to the other.

摘要： A method and associated apparatus for embedding control information in a data signal to be transmitted over a data link by a network node includes the generation of control information to be transmitted over a data link by a network node. Additionally, a transmission signal is generated by combining the control information with data to be transmitted. In an embodiment of the present invention, the data is transmitted within a prescribed frequency bandwidth such that a frequency gap is defined within the frequency bandwidth. Control information is, as such, transmitted within the defined frequency gap.

摘要： An optical receiver, e.g., receiver 10 (FIG. 1), has differential optical input beams and generates an electrical output. The voltage at an electrical node between series-connected optical detector diodes is clamped within a predefined voltage range by series-connected clamping diodes, to prevent the voltage from increasing when consecutive logic one optical input beams are received. Variable bandwidth and low energy dissipation are achieved since the resistors of high input impedance and transimpedance receivers are not required. A second optical receiver, e.g., receiver 20 (FIG. 2) is a monolithic, diode-clamped S-SEED with complementary optical input beams and complementary optical output beams.

摘要： A network arrangement and control method where, before any transmission of data occurs for a particular communication, a network controller determines an unused path to provide a connection, advantageously all the way through the network from a given inlet to a given outlet. Once the identity of the unused path is known, the controller determines control information for use in activating that path and transmits that control information into the network, significantly via the network inlets. The network responds by activating the determined path and communication is enabled via the activated path, but only for the single connection and no buffering of information is required within the network. The network is particularly well suited for optical implementation and control is effected without the use of spatial light modulators but rather by means of control elements embedded within the network itself.

摘要： Apparatus having a plurality of photodetectors interconnected to form an electrical circuit corresponding to any given logic function comprising at least two of the four basic AND, OR, NAND, and NOR logic operations. The apparatus performs optical logic without optical cascading since the electrical circuit controls the generation of an optical output beam based on the value that the given logic function assumes in response to a plurality of optical signal beams each incident on at least one of the photodetectors. A complementary optical output is obtained and time-sequential operation is effected when two, serially connected quantum well p-i-n diodes comprising an S-SEED are used to generate optical output beams in response to the voltage developed by the electrical circuit of interconnected photodetectors.

摘要： A tri-state optical device 400 is disclosed having photodiodes 401 and 402 with respective quantum-wells 403 and 404 in the intrinsic regions. The photodiodes are connected in series with a bipolar switch 406 and a source of electrical potential 405 for emitting a pair of optical output beams having various combinations of power levels depending on the state of the bipolar switch and the ratio of two optical control beams incident on the photodiodes. In one state of the tri-state device with the bipolar switch in a conducting state, the two output beams have complementary high and low power levels representing, for example, high and low logic levels "1" and "0". In a second state, the power levels of the two output beams are reversed, thus exhibiting complementary and symmetric output power levels. In the third state when the bipolar switch of the tri-state device in a nonconducting state, the output beams both exhibit a low power level, and the tri-state device is nonresponsive to the power levels of the optical control beams.

摘要： Optical devices, phased array systems and methods of phase-shifting an input signal are provided. An optical device includes a microresonator and a waveguide for receiving an input optical signal. The waveguide includes a segment coupled to the microresonator with a coupling coefficient such that the waveguide is overcoupled to the microresonator. The microresonator receives the input optical signal via the waveguide and phase-shifts the input optical signal to form an output optical signal. The output optical signal is coupled into the waveguide via the microresonator and transmitted by the waveguide. At an operating point of the optical device, the coupling coefficient is selected to reduce a change in an amplitude of the output optical signal and to increase a change in a phase of the output optical signal, relative to the input optical signal.

摘要： A module that includes both an “add-in”/“drop-out” pair of ports and a “drop-in”/“add-out” pair of ports comprises an arrangement of elements that combines an optical signal having a chosen wavelength with an optical signal applied at the “add-in” port, and outputs the combined signal at the “add-out port.” Concurrently, the module extracts an optical signal with the same wavelength from an optical signal applied at the “drop-in” port signal, yielding an optical signal at the “drop-out” port that is missing that same wavelength. When the amount of information that needs to be sent from a first network node to a second, remote, node, is greater than that which a single wavelength can handle, a plurality of the above-described modules are interconnected within the first node by optically coupling the “add” ports in a “daisy chain” fashion and the “drop” ports in a “daisy chain” fashion, with each module operating at a different wavelength.

摘要： A multi-stage network which achieves the same overall connectivity as known networks but where individual switching nodes have no input selectivity and no output selectivity. Each node is enabled or disabled to control communication therethrough in response to a single control signal. The functionality of a switching network is achieved by controlling which nodes are enabled rather than specifying connections of particular node inputs and outputs to be effected by the nodes. In a photonic network embodiment, each network node is implemented using a single symmetric self electro-optic effect device (S-SEED).
