摘要： A hybrid optical transmission system comprising an optical transmitter and receiver. The transmitter includes an input for receiving an encoding signal and an encoder arranged to encode an optical signal with any one of a plurality of encoding signatures according to the encoding signal. The optical receiver comprises a grating decoder connected to receive the encoded optical signal from the input, the grating decoder incorporating a decoding signature complementary to a matched one of the encoding signatures so as to decode the encoded optical signal when encoded with the matched one of the encoding signatures. A hybrid system is thus provided that uses (passive) grating decoders at the receiver in combination with active drive-signal-based encoders at the transmitter. In this way, flexibility can be retained for the transmitter hardware, whereas the advantages of grating decoders can be exploited at the receivers.

摘要： Optical code division multiple access (OCDMA) coder: decoder gratings have been fabricated. The modulated refractive index profile that makes up the OCDMA coder: decoder grating incorporates changes in polarity between OCDMA chips by discrete phase shifts, thereby to provide bipolar coding through phase modulation. (In another embodiment quadrupolar coding is achieved). For NRZ modulation, each grating section is either in phase with, or has a predetermined phase shift relative to, the preceding grating section, depending on whether the OCDMA signature has a change in polarity between chips. RZ modulation is also possible. Results are presented from specific examples of bipolar OCDMA with NRZ modulation, which show higher data rates (10 Gbit/s), shorter chip-lengths (6.4ps) and far longer code sequences (63 bits) than previously demonstrated. Other embodiments relate to optical packet switching, for example using the Internet Protocol (IP) or Asynchronous Transfer Mode (ATM).

摘要： An optical fibre device based on the Raman effect comprises a first optical source to provide light at a first wavelength, and a holey optical fibre which receives the light from the first optical source such that optical gain or loss is provided at a second wavelength by the effect of Raman scattering within the fibre. For optical gain, the second wavelength is longer than the first wavelength, and the device can be operated as an amplifier, or as a laser if optical feedback is provided. For optical loss, the second wavelength is shorter than the first, and the device may be used as an optical modulator. The fibre may be fabricated from pure silica, although other undoped or doped materials may alternatively be used to tailor properties of the fibre such as gain spectrum, bandwidth, power handling capability and mode propagation.

摘要： A source of optical pulses, comprises an optical source operable to generate ultrashort optical pulses at a first wavelength; and an optical fiber amplifier comprising an optical fiber having a core containing a dopant to provide optical gain at the first wavelength, and anomalous dispersion over a wavelength range including the first wavelength and a second wavelength. The optical fiber receives the ultrashort optical pulses, amplifies the ultrashort optical pulses, and alters the wavelength of the ultrashort optical pulses to at least the second wavelength by the soliton-self-frequency shifting effect. Microstructured and/or tapered fibers can be used to provide the required dispersion characteristics. Pulses can be generated in one of three spectral regimes - monocolor solitons, multicolor solitons and continuous broadband spectra by adjusting the energy of the optical pulses, and tunability can be achieved by varying the power of pump light provided to the amplifier.

摘要： Apparatus for monitoring and/or restricting access to individual items each provided with a unique identifying code comprises a console provided with a plurality of identical receptacles each for retaining one of a plurality of items. The receptacles are scanned one by one by a microprocessor and the identity of each of the items in the receptacles is obtained and recorded. When a user wishes to obtain an item he first identifies himself to the microprocessor using an identity card read by a card reader and by inputting a personal identity number by a keyboard. The item the user wishes is then identified to the computer using a keyboard and if all input information relating to user and item is correct the microprocessor causes an indicator lamp to be lit adjacent the receptacle containing the desired item and for a retaining latch holding the item in the receptacle to be released thus permitting the user to take the item. Details relating to the user, the item taken and the time of day are recorded.
