The input signal is amplified and the interferometer adjusted to place the input signal across an entire monotonic portion of a sinusoidal transfer function to the wavelength-converted output signal. Retiming is effected by wavelength converters including pulsed laser sources of the output wavelength. A multi-wavelength regenerator may be integrated on a chip including two arrayed waveguides and an array of tunable lasers on parallel waveguides therebetween.

摘要： A variable optical buffer queue, particularly useful either as an input or an output queue in an optical packet router in a wavelength-division multiplexing (WDM) communication network. An input queue includes plural separately controllable optical delay units disposed on wavelength channels between a demultiplexer and tunable wavelength converters controlling switching through a wavelength router. An output queue includes for each output port of a wavelength router plural separately controllable optical delay units tuned to different wavelengths. The delay units may induce selective amounts of delay and may be implemented as a series of controlled microresonators coupled to waveguide. Such a structure is usable as a controllably accessible optical memory.

摘要： An edge router for interfacing an optical label switched core IP network with client networks, which may be electronically switched and operate with different protocol. The core network has a limited number of ports, each with an edge router, which receives packets from one or more associated client networks and queues them according to egress port on the core network and optionally additionally according to attribute of service. When a queue has exceed a maximum packet length or a timeout limit assigned to the queue, the packets including their headers are assembled into a super packet for transmission across the core network in optical form, preferably using optical routers incorporating wavelength conversion of payloads and switching according to an attached label. The edge router at the egress port disassembles the super packet into constituent packets for respective destinations on the client network.

摘要： An optical wavelength converter, particularly useful in a wavelength-division multiplexing communication system, including a semiconductor junction (54) in one arm (36) of a Mach-Zehnder interferometer (52) through which a data signal at a first wavelength (λ 1 ) and a probe signal at a second wavelength (λ 2 ) counter propagate. The junction is reversed biased into avalanche to selectively absorb the data signal and thereby phase modulate the probe signal according to the data impressed on the data signal. The phase modulated probe signal is beat against an unmodulated probe signal, thereby converting the wavelength of the optical carrier. A tunable laser (60) may produce a probe signal of selectable wavelength. The data signal may first be converted by cross-gain modulation (90) to a third wavelength (λ 3 ) out of band from the other signals before it is interacts with the probe signal.
