摘要： Disclosed is a Gunn-effect device comprising, for example, a crystal of n-type gallium arsenide having alloyed contacts (e.g., indium and gold) which is switched from one frequency of oscillation to another by controlling the incident light while maintaining an appropriate temperature and bias voltage. It is believed that trap zones which are localized within the crystal by virtue of introducing acceptor impurities account for a frequency of oscillation different from the usual transit-time frequency. The Gunn domains and the incident light are made to dynamically perturb the trap system so as to achieve a nonequilibrium condition.

摘要： A light-controlled oscillator includes a circuit device, a detection circuit and a control circuit. The circuit device changes its characteristics when light is applied, so that a frequency of the oscillation shifts. The detection circuit detects a change of the characteristics caused according to the applied light. The control circuit controls an operation of the oscillator to increase a shift of the frequency of the oscillation according to the change of the characteristics. The oscillation frequency can be shifted by a desired amount only by detecting a change of characteristics based on a condition of the light, even when the intensity of the light is small.

摘要： Arrangement for modulating the output signal of a converter converting electric signals into other signals, for example optical signals. An analog signal is applied to a difference producer (6) the output signal of which controls a limiter (7). The binary output signal thereof controls the semiconductor laser diode (1) which is coupled to a photo-sensitive detector (3) for producing a feedback signal. After having been amplified in a broadband amplifier (9) and integrated in an integrator (13), this feedback signal is applied to the difference producer (6), in which the feedback signal is substracted from the analog signal. Variations in the optical output signal due to a non-linear conversion characteristic of the laser diode (1) and due to an optical retroaction of the fibre (2) on the laser diode (1) as well as output noise and signal-dependent amplitude variations are reduced by the negative feedback.
Use: Optical transmission systems.

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.
