摘要： A semiconductor light-emitting device includes a pair of clad layers and an active layer sandwiched thereby which together are disposed between a substrate and a cap layer so as to form a monolithic array of double-heterojunction regions each including therein a plurality of light-emitting portions of the active layer for emitting light from the end face thereof so that the light-emitting portions are arrayed in a row and electrically separated from each other. The substrate is formed at one side thereof with a concave and convex configuration following a stripe pattern so that the clad layers, active layers and the cap layers are each arranged in the form of a corrugated configuration following the concave and convex configuration of the substrate. According to the corrugated configuration of the active layer between said clad layers, one of the clad layers has portions which are each disposed between respective two successive light-emitting portions of the active layer along an array line thereof, so that when at least two successive light-emitting portions are activated to emit light, these successive light-emitting portions are also photo-coupled to each other through the corresponding portion of the clad layer disposed therebetween.

摘要： A self-tuning mode locked semi-conductor laser automatically adjusts itself to produce short (less than 200 ps and preferably less than 50 ps) stable optical pulses. Tuning is achieved by means of a feedback loop which includes a spectrum analyzer (18) which receives a small amount of the optical output of the laser and monitors the spectral wavelength, spectral width or spectral shape of the output. A controller (19) is connected to said analyzer and produces a control signal based on said spectral information. The control signal causes adjustment of one or more parameters influencing operation of said laser, such as frequency or power of an RF drive signal, level of dc bias, cavity length, for example, in order to produce said short stable pulses.

摘要： A stabilized optical pulse generator using RHML-FRL is provided. The stabilized optical pulse generator comprises an optical fiber ring composed of optical fibers, an optical amplifier and a modulator for optical modulation, an electric signal generator generating high frequency signals and an optical pulse stabilizer. The device generates an optical pulse train of repeating frequency of fm, when applying electric signals of frequency of fm to the modulator. Wherein, for a resonance frequency of the optical fibers of fc, the modulating frequency applying to the modulator is detuned from the electric signal of the frequency of fm by frequency of the resonance frequency fc divided by integer of p. Optical pulse trains of repeating frequency of p times of fm+fc/p or fm−fc/p are generated. The optical pulse trains are stabilized by suppressing carrier components and a part of high frequency components as well as suppressing the random oscillations of the cavity resonance modes and intermediate longitudinal modes with respect to the main longitudinal modes which are frequency spaced that is equal to the repetition frequency of the generated optical pulse trains.
