摘要： A multiwavelength transmitter comprises several laser sources (1) each configured to generate light of a different wavelength and a first array waveguide grating (2) arranged to direct light from each of the laser sources (1) into a first waveguide. The transmitter further comprises several electroabsorption modulators (7) each arranged to modulate light at one of the wavelengths with a respective data signal and a second array waveguide grating (6) arranged to direct each of said different wavelengths of light from the first waveguide to a respective one of the modulators (7). The optical modulators (7) are reflective optical modulators and the second array waveguide grating (6) is arranged to direct the modulated light reflected from each of the optical modulators (7) back into the first waveguide. An optical circulator (5) is provided in the first waveguide to couple modulated light from the second array waveguide grating (6) into an output waveguide. The laser sources each comprise a respective reflective semiconductor optical amplifier (1) and share a common cavity reflector (3). The first array waveguide grating (2) is located in the optical path between the semiconductor optical amplifiers (1) and the common cavity reflector (3). The transmitter has the advantage that it can be manufactured by hybrid integration of a monolithic wavelength generation sub-module and a monolithic data modulation sub-module.

摘要： The present invention relates to a method of optical communication, in particular optical communication involving spectral filtering in a passive optical network. The method includes the steps of: (i) performing a first spectral filtering function on a source signal having a spectral width so as to generate a plurality of feeder signals that are spectrally spaced apart from one another; (ii) performing a respective noise reduction function on the feeder signals; (iii) combining the feeder signals over a common waveguide of the optical link; (iv) receiving the feeder signals carried over the optical link and modulating the received feeder signals so as to impose data thereon; and, (v) returning the modulated feeder signals over the optical link so as to communicate the imposed data. Because noise is reduced centrally, a simpler passive optical network can be achieved.

摘要： A device and method for quantifying the amount of jitter experienced by an optical data pulse. During transmission data pulses may suffer jitter. Their arrival time at a node may be temporally offset from its predicted arrival time. Data pulses are timed so that they may be received at a detector disposed downstream of said node at a predetermined time. The device includes an optical AND gate, which has a first input arranged to receive a chirped pulse having a duration T, and whose wavelength varies in a monotonically over the duration of the pulse, the node having a second input arranged to receive a second data pulse. The node includes an optical gate arranged to generate an output pulse in response to the chirped pulse and the data pulse received at the first and second inputs, respectively, having a wavelength dependent upon the time at which the data pulse is received at the second input.

摘要： An optical filter and method of filtering uses a multi-mode waveguide having a first number n modes and a second waveguide having a different number m modes are coupled in series, where n and m are integers and n>m, and where the interaction of different modes at the interface of the two waveguides filters an optical signal propagating through the waveguides to provide a desired response characteristic. A lateral offset between the central axes of the waveguides at their interface is changed to control the response of the filter. For a multiple wavelength optical source uses, a filter coupled in the optical cavity including a laser gain medium provides interaction of different modes at the interface of waveguides in the filter to filter an optical signal propagating in the cavity thereby providing an output signal with multiple peaks at different wavelengths with a predetermined spacing.
