Abstract

The process and the arrangement for generating the rapid light pulse generator consists in the coupling of 2 DFWM arrangements in opposition.

Description

Die Erfindung betrifft die Darstellung eines optischen Lichtpulsgenerators wie er zum Takten von möglichen optischen Computern im Höchstfrequenzbereich benötigt wird.The invention relates to the representation of an optical Light pulse generator like him for clocking possible optical computers in the high frequency range becomes.

Bisher sind keine solchen rein optischen Lichtpulsgeneratoren bekannt.So far there are no such purely optical light pulse generators known.

Der Erfindung liegt die Aufgabe zugrunde, einen Takt­ generator zu schaffen zum Takten möglicher optischer digitaler Computer im Gigahertzbereich.The invention has for its object a clock to create generator for clocking possible optical digital computer in the gigahertz range.

Diese Aufgabe wird erfindungsgemäß durch ein spezielles Verfahren und eine spezielle Anordnung gelöst, die nach­ folgend beschrieben werden.This object is achieved by a special Procedure and a special arrangement solved according to are described below.

Zur Erzeugung eines rein optischen Lichtpulsgenerators werden zwei Vierphotonenwechselwirkungsexperimente (DFWM: Degenerates Four Wave Mixing) in Rückwärtsstreu­ geometrie so angeordnet, daß sie von den gleichen Pump­ strahlen gepumpt werden; siehe Figur.To generate a purely optical light pulse generator are two four-photon interaction experiments (DFWM: Degenerate Four Wave Mixing) in backward scatter Geometry arranged so that it is from the same pump rays are pumped; see figure.

Figur Koppelung zweier DFWM-Anordnungen zur Erzeugung eines Lichtpulsgenerators. Figure coupling two DFWM arrangements for generation a light pulse generator.  

Die experimentelle Bedingungen werden so gewählt, daß in einer DFWM-Anordnung Selbstoszillation auftritt /1/. Das Signal der selbstoszillierenden DFWM-Anordnung wird nun mittels Spiegeln als Probestrahl in die zweite DFWM- Anordnung eingespiegelt. Wegen dem nun einsetzenden DFWM- Prozeß der zweiten Anordnung bricht die Selbstoszillation in der ersten DFWM-Anordnung zusammen, wenn die experimen­ tellen Bedingungen so gewählt sind, daß durch die Änderung der komplexen Pumpstrahlamplituden die Selbstoszillations­ bedingung der ersten Anordnung nicht mehr erreicht wird. Die experimentellen Bedingungen sind so gewählt, daß in der zweiten DFWM-Anordnung keine Selbstoszillation auf­ treten kann. Dadurch bricht der gesamte DFWM-Prozeß zu­ sammen. Da nun durch die erneute Änderung der Pumpstrahl­ amplituden wieder die Oszillationsbedingung der ersten DFWM-Anordnung erreicht ist, schwingt diese wieder an und der Vorgang wiederholt sich periodisch durch die Rückkopp­ lung der beiden DFWM-Anordnungen über das Pumpstrahlfeld.The experimental conditions are chosen so that Self-oscillation occurs in a DFWM arrangement / 1 /. The signal of the self-oscillating DFWM arrangement is now by means of mirroring as a test beam in the second DFWM Arrangement mirrored. Because of the DFWM The process of the second arrangement breaks the self-oscillation in the first DFWM arrangement when the experiments tellen conditions are chosen so that by the change of the complex pump beam amplitudes the self-oscillation condition of the first arrangement is no longer achieved. The experimental conditions are chosen so that in the second DFWM arrangement shows no self-oscillation can kick. As a result, the entire DFWM process breaks down together. Because now by changing the pump jet again amplify again the oscillation condition of the first DFWM arrangement is reached, this swings back and the process is repeated periodically through the feedback the two DFWM arrangements via the pump beam field.

Oben beschriebenes Verfahren und Anordnung stellt somit in Analogie zu einem elektronischen Oszillator (rückgekoppel­ ter Verstärker) einen Lichtpulsgenerator dar, bei dem das Taktverhältnis und die Taktfrequenz durch die Länge des Lichtweges zwischen den beiden DFWM-Anordnungen gewählt werden kann.The method and arrangement described above thus represents in Analogy to an electronic oscillator (feedback ter amplifier) is a light pulse generator in which the Clock ratio and the clock frequency by the length of the Light path chosen between the two DFWM arrangements can be.

Vorteileadvantages

Die maximale Frequenz, mit der die Lichtpulse erzeugt werden können, ist die inverse Ansprechzeit des DFWM- Prozesses und kann daher im 1/ps = Terrahertzbereich liegen.The maximum frequency at which the light pulses are generated is the inverse response time of the DFWM Process and can therefore in the 1 / ps = Terrahertz range lie.

Mittels des oben beschriebenen Verfahrens und Anordnung können, wenn die Lichtsignale mittels schneller Photodio­ den in elektrische Signale gewandelt werden, schnelle elek­ tronische Pulsgeneratoren dargestellt werden. Using the method and arrangement described above can, if the light signals by means of fast Photodio which are converted into electrical signals, fast elec tronic pulse generators are shown.
