摘要： An optical circuit comprises a bistable optical waveguide (34) having a first and a second transmission state. The waveguide is more transmissive to light of a given wavelength in the second state than in the first state. A first light source (11) and a second light source (21) emit light of a first and second wavelength respectively and are coupled to the waveguide at one end. Selective transmission of a sufficient amount of light of the first wavelength through the waveguide “sets” the waveguide, causing it to switch from the first into the second state, whereas transmission of a sufficient amount of light of the second wavelength “resets” the waveguide causing it to switch back from the second into the first state. A sensing or reading (“test”) light source (36) is arranged at the other end of the waveguide to transmit a sensing light signal through the waveguide (34) in the opposite propagation direction to that of light of the first and second wavelengths. This sensing light source can be an external light source or an “internal” source provided by spontaneous emission in the waveguide. A sensor (38) is arranged to detect the amount of the sensing light signal transmitted through the waveguide (34). In this way the waveguide can be set into a given transmission state, which can be determined at a later time by measuring the amount of the sensing light signal transmitted. The optical circuit therefore exhibits a memory effect and may be used to produce an all-optical bistable logic circuit such as an optical latch or an optical flip-flip. Typically, the waveguide (34) is a doped optical fibre, such as an Erbium-Ytterbium (Er—Yb) doped fibre. Light of the first (set)/second (reset) wavelengths excites or de-excites respectively the dopant ions in the fibre thus tuning its transmission.

摘要： A method (10) of configuring a synchronous optical switch to route received data cells. The synchronous optical switch comprises optical switch transmitter modules, each comprising tunable optical transmitters, optical switch receiver modules, each comprising optical receivers, and optical connections between the transmitter modules and receiver modules. For each optical switch transmitter module, the method: assigns (12) wavelengths associated with the received data cells to the transmitters such that each wavelength is assigned to a different transmitter; and generates (14) a control signal for controlling the operating wavelength of each transmitter. For each wavelength, the method: allocates (16) to each transmitter an optical connection such that each optical switch transmitter module has no more than one connection exiting it at said wavelength and each optical receiver module has no more than one connection entering it at said wavelength; and generates (18) a control signal for connecting each transmitter to the respective optical connection.

摘要： A node (260) for an optical communications network in which a token is passed between nodes, indicating that a corresponding optical channel is available for transmission during a token holding time while that node holds that token, until it passes the token to another node. A transmit controller (290) determines a traffic class of said packet and controls a buffer to forward a packet from the buffer to the transmitter according to the traffic class, if there is sufficient of the token holding time remaining before the received token must be passed on to another node for said packet to be transmitted by the transmitter over an optical channel corresponding to the received token. By having the packet forwarding dependent on traffic class, packets can be handled differently to suit different characteristics of the traffic classes.
