摘要： Disclosed is a telecommunications link having positively chirped optical signal pulses propagating in an optical waveguide fiber (52), at least a portion of which is characterized by a negative chromatic dispersion. An embodiment of the invention is a semiconductor laser source (46) in combination with negative dispersion optical waveguide fiber (52). The source (46) of the chirped signal pulses is selected to have predominantly adiabatic chirp as evidenced, in the case of a DFB laser (46), by a gain compression factor in the range of 4 x (10 power of -23)x(m power of 3) to 30x (10 power of -23) x(m power of 3). Eye closure penalty and bit error rate are maintained low for link lengths having cumulative dispersion parameter times distance product of the order of thousands of ps/nm. Optimum laser extinction ratio is found to be in the range of 5 to 10 dB, although extinction ratios as high as 20 dB are contemplated.

摘要： A method and apparatus for pulse frequency modulation for analog optical communication. A train of optical pulses is generated. The spectrum of the optical pulses in the train of optical pulses can be broadened to provide a train of broad spectrum optical pulses. The broadening can be provided by self-phase modulation. Alternatively, broad spectrum optical pulses can be provided by merely having the optical pulses be less than 1ps duration. A desired optical frequency slice from the train of spectrum broadened optical pulses is selected by a tunable Fabry-Perot filter. A desired optical frequency slice from the broad spectrum optical pulses is selected by a tunable Fabry-Perot filter. The tunable Fabry-Perot filter has a pair of Distributed Bragg Reflectors separated by an electro-refractive section. The electro-refractive section has tuning electrodes for applying transverse electric fields to the electro-refractive section, corresponding to an analog waveform being applied to the tuning electrodes, to provide a pulse-frequency modulated train of optical pulses.

摘要： Code-multiplexed communication systems (100), apparatus, and methods include coders (Fig.1) that encode and decode data streams with synchronous, substantially orthogonal codes. Code-multiplexed communications systems (100) encode data signals with such codes to control levels of decoding artifacts such as cross-talk at times or time intervals in which data is recovered. Some systems are based on synchronous, orthogonal codes that are obtained from complex orthogonal vectors. In an example, a three-level temporal-phase code that includes nine code chips is used to encodes and decodes data signals is a seven-channel communication system.

摘要： A method and apparatus for converting a frequency modulated lightwave into an electrical signal that is proportional to instantaneous frequency deviations of the frequency modulated lightwave. The frequency modulated lightwave is amplified by an amount equal to or greater than a desired FM processing gain to provide an amplified frequency modulated lightwave. The amplified lightwave is filtered to restrict amplifier noise added to the frequency modulated lightwave to provide a filtered lightwave. The amplitude of the filtered lightwave is limited to remove unwanted amplitude fluctuations to provide a limited lightwave. The limited lightwave is split into a first split lightwave and a second split lightwave. The second split lightwave is delayed relative to the first split lightwave, to provide a delayed second split lightwave. The delayed second split lightwave is combined with the first split lightwave to provide: (1) a sum of first split lightwave fields and delayed second split lightwave fields, and (2) a difference of the first split lightwave fields and the delayed second split lightwave fields, the splitting, delaying and combining providing the sum and the difference having fields with parallel polarizations. The sum is detected by a first photodetector and the difference is detected by a second photodetector, the first photodetector and second photodetector being connected in series with a common terminal therebetween, the common terminal providing to a following amplifier a difference current that is proportional to a difference between first photodetector current and second photodetector current, the difference current being proportional to instantaneous frequency deviation of the frequency modulated lightwave.

摘要： A multiwavelength light source device has a variable wavelength light source, a light intensity modulator, a photocoupler, an annular optical delay circuit and an optical gate device. The variable wavelength light source outputs output lights with a plurality of different wavelengths by switching them successively. The light intensity modulator subjects the output lights from the variable wavelength light source to amplitude modulation for a predetermined time and outputs the modulated signal lights. The photocoupler is optically connected to the light intensity modulator and receives the output lights from the light intensity modulator. The annular optical delay circuit is optically connected to the photocoupler and delays a part of the output lights from the light intensity modulator for a time longer than the predetermined time. The optical gate device is optically connected to the photocoupler, receives the output light from the light intensity modulator and a light through the annular optical delay circuit and opens its gate at such a timing and with such a time width as to include all the signal lights modulated for the predetermined time one each for each wavelength of the plurality of different wavelengths.

摘要： An optical CDMA system is implemented at least partially within a photonic integrated circuit. A broad-spectrum light source is modulated with data to be transmitted. The light source is spatially dispersed, for example using a diffraction grating, and passed through a spatial spectrum-coding mask embodied within the photonic integrated circuit. The dispersed frequencies of the encoded modulated light beam are then recombined to provide a modulated, encoded spread spectrum optical signal for injection into an optical fiber or another optical communication system. Received light is split into two components and provided to a pair of complementary decoders. Within each of the complementary encoders, the received portion of the light beam is spatially dispersed and passed through a spatial decoding mask. Both the dispersion element and the mask are embodied within the photonic integrated circuit. One of the decoders includes a spatial decoding mask that embodies the spatial encoding function U of the original transmitting mask and the other, complementary decoder includes a complementary function U*. Within each of the complementary decoders the spatially spread light signals are recombined after passing through the decoding masks. The signals passing through the complementary decoding masks are then provided to different inputs of a differential detector and the data originally modulated within the light is recovered.

摘要： A current mode transmitter is provided including a charge circuit (34) connected to an enable node and adapted to generate a charge current (Ic) upon the receipt of an activation signal at the enable node. Also included is a discharge circuit (36) connected to the enable node and adapted to generate a discharge current (ID) upon the cessation of the receipt of the activation signal at the enable node. An output circuit is connected between on output node and the change and dischange circuits. The output circuit serves for generating an output current. Such output current is initiated with a first delay after the detection of the activation signal by the charge circuit. Further, the output current is terminated within a second delay after the detection of the cessation of the receipt of the activation signal by the discharge circuit. The first delay and the second delay are substantially similar such that a pulse width of the output current is substantially similar to a pulse width of the activation signal received at the enable node. The output current may thus be used to drive an infrared light emitting diode with very fast rise and fall times while maintaining tight control over the pulse width of the output current.
