摘要： The invention provides a multi-carrier system for use in an optical network adapted to transmit and/or receive signals, said system comprising means for recovering multiple phase-synchronised sub-carriers from at least one signal in the network; means for recovering a clock signal from the sub-carriers and determining the frequency and the phase change between sub-carriers; and means for compensating the signal using said clock signal. The clock signal can be re-used for new generation of same frequency spacing subcarriers (and phase-locked) to the original signal. Any fluctuations of both frequency and the phase from the original phase-synchronised signal is transferred also to the clock signal, and therefore, using appropriate feedback electronics, compensation can be provided at a transmitter/receiver. Suitable for Optical Orthogonal Frequency Division Multiplexing (OFDM) and Coherent WDM multi-carrier systems.

摘要： The invention provides a linear burst mode receiver comprising a first amplifier connected to a photodiode adapted to detect an optical input burst signal, a second amplifier connected to said photodiode; and means for deriving the peak input current of the detected burst signal using said second amplifier. The invention further provides means for using the derived peak input current to adjust the gain of the first amplifier during the preamble of each burst, such that the output voltage swing of the first amplifier equals a given reference, independent of the strength of the optical input burst signal. The usage of the fast feed-forward automatic gain control mechanism solves the problems with gain switching and non-linearity prevalent in today's burst-mode receivers.

摘要： An optical transmitter is of the reflective modulation type and has a means of generating reflection, a mixer for mixing a data stream and a sub-carrier, and an optical modulator for modulating an optical carrier with the output from the mixer in order to avoid optical beat-interference noise arising from, for example, Rayleigh backscattering. The modulator is in one embodiment of the interferometric type such as a Mach-Zehnder Modulator (MZM) operated to suppress the optical carrier at the transmitter output in order to reduce optical beat interference noise. The modulator preferably implements CSS-AMPSK modulation, which suppresses optical beat noise and achieves strong dispersion tolerance, enabling, for example, 10Gb/s data transmission over 100km distance without dispersion compensation. The transmitter may have a duobinary encoder, which encodes the data prior to mixing with the sub- carrier.

摘要： A method of assessing the allergic status of a subject to a specific allergen, comprises the steps of determining a subject-specific numeric value for a plurality of variables comprising age, sex, SPT, IgE, (sIgE or tIgE minus sIgE) and allergic symptoms, applying an allergen-specific weighting to the numeric value for each variable, and correlating the weighted numeric values with allergic status for the subject. The weighted numeric values may be correlated with allergenicity status using a linear regression model P = ez/(1= ez) in which: P = predicted allergenicity status for the subject; e = mathematical constant (2.71828....); and z = linear combination of the weighted numeric values for the variables.

摘要： An array of highly efficient micro-LEDs (100) and a manufacturing process are described. Each micro-LED (100) is an integrated diode structure in a mesa (105), in which the mesa shape and the light-emitting region (104) are chosen for optimum efficiency. A single one of the micro-LEDs (100) comprises, on a substrate (101) and a semiconductor layer (102), a mesa (103), a light emitting layer (104), and an electrical contact (106). The micro-LEDs in this device have a very high EE because of their shape. Light is generated within the mesa, which is shaped to enhance the escape probability of the light. Very high EEs are achieved, particularly with a nearparabolic mesa that has a high aspect ratio. The top of the mesa is truncated above the light-emitting layer (LEL), providing a flat surface for the electrical contact (106) on the top of the semiconductor mesa. It has been found that the efficiency is high provided the top contact has a good reflectivity value. Also, it has been found that efficiency is particularly high if the contact (106) occupies an area of less than 16% of the truncated top mesa surface area. This feature also helps to achieve a more directional beam in the case of the device being an LED.

摘要： The invention provides time-synchronised transmission of data on the (polarisation or phase-modulated) QKD channel and the (on-off modulated) conventional channel such that a QKD bit is only transmitted when a zero, or sequence of zeros, is transmitted on the conventional channel. Also, there is co-directional propagation of the QKD and conventional channel. Further, there is dispersion management through wavelength selection or control of fibre properties or other means such that the 'walk-off' in time of the QKD pulses and the Raman pulses generated by the ones on the conventional channel is less than or of the order of one bit period. The latter can be achieved, for example, by placing the conventional and QKD channel wavelengths close to the point where the group velocity-induced time delay for optical pulses propagating in the fibre reaches a minimum. This dispersion minimum occurs at a wavelength of 1.3microns in standard fibre.
