摘要： The present invention discloses a method and a device for conversion of an optical data signal from a multimode fibre (1), which except for normal data signals may contain interruptions and an overmodulated low frequency signal, to a corresponding signal which is transmitted further into a single mode fibre (8) by a laser (7). An electric signal from an optical receiver (2) partly directly and partly through a low pass filter (4) is coupled to a comparator (5) the output of which modulates the laser (7). Upon detection of an optical interruption the low pass filter (4) is influenced such that its output signal is stored in a memory device, and the laser is influenced by diversion of the laser current, simultaneously as an analogue value in the control loop of the laser is stored. When the interruption ends both the laser transmitter (7) and the low pass filter (4) continue to operate as before on the basis of their stored analogue values.

摘要： In the disclosed laser communication system, at a transmitter a linearly polarized laser carrier beam is phase modulated with an informational signal such that when the resultant beam is resolved into two linearly polarized component beams in mutually perpendicular planes the respective component beams are shifted forwardly and backwardly in phase by an amount proportional to the informational signal. In a receiver the received phase modulated beam is combined with a local oscillator laser beam which is linearly polarized in a plane parallel to the plane of polarization of the carrier beam, and the resultant beam is separated into a pair of linearly polarized laser beams in respective planes parallel to the planes of the aforementioned transmitter component beams. These linearly polarized laser beams are converted into respective intermediate frequency electrical signals, and a reproduction of the informational signal is obtained by phase comparing these electrical signals.

摘要： Optical signal receivers and methods are provided that include an optical resonator that allows an optical signal to enter and optical signal energy to accumulate at regions inside the optical resonator. A portion of optical signal energy is emitted from among various regions of the optical resonator, such that a combination of the emitted optical signal energy is disturbed when a phase transition occurs in the received optical signal. A detector aligned with the output detects the combined emitted optical signal energy and is configured to detect the disturbance and determine a characteristic of the phase transition in the received optical signal based upon the disturbance.

摘要： An optical receiver includes a cascade of optical filtering elements, each of which selects spectral components from incoming optical signals at a wavelengths aligned to filter passbands. The selected spectral components may be optically combined to form k pairs of intermediary signals, where k=log2(M). By comparing the k pairs of intermediary signals, k bits of a digital signal representing the incident signal may be generated. The filtering elements may be configured to perform demultiplexing and demodulation simultaneously, increasing functionality and reducing excess losses. The filtering elements may also be tuned so that the optical receiver may be reconfigured to accommodate different combinations of wavelengths and modulation formats, such as wavelength division multiplexed (WDM) on off keying (OOK), M-ary orthogonal formats including frequency shift keying (FSK) and pulse position modulation (PPM), differential phase shift keying, and hybrid combinations—providing rate and format flexibility and WDM scalability.
