摘要： Um die grosse Übertragungskapazität von Monomode- Übertragungssystemen voll ausnutzen zu können, wird eine integriert-optische Wellenlängenmultiplex- und -demultiplexein richtung für Monomode-Systeme angegeben. Wie in Fig. 1 dargestellt, besteht sie aus einem lateral zweimodigen Streifen wellenleiter (11), an den jeweils auf beiden Seiten zwei Mono mode-Streifenwellenleiter (12, 13) angeschlossen sind.
Die Wellenlängenselektivität dieses Bauelements wird durch die unterschiedlichen Modendispersionen der beiden in dem zweimodigen Streifenwellenleiter ausbreitungsfähigen Moden erreicht. Die Ankopplung dieser Moden an die Mono mode-Streifenwellenleiter erfolgt durch adiabatische Modenkon version. Bedingt durch das Funktionsprinzip der Zweimodenin terferenz besitzt das Bauelement eine periodische Wellen längenabhängigkeit. Diese wird dazu ausgenutzt, kompakte Viel kanal-Multiplexer/-Demultiplexer in Form einer Baumstruktur aufzubauen.
Bei der Erstellung des Multiplexers/Demultiplexers in ge eigneten Materialien bietet sich auch nach dem Herstellungspro zess die Möglichkeit, die Wellenlängenabhängigkeit und das Aufteilungsverhältnis zwischen den Lichtleistungen in den bei den Ausgangswellenleitern mit Hilfe zahlreicher Einrichtungen zu verändern.

摘要： An opto-optical light deflector/modulator has means (14, 16, 18, 20) for providing first (10) and second (12) coherent wave fronts of wavelength (λo) to travel in a transparent optical acitve medium (22) to produce an optically generated standing wave that induces a periodic refractive index variation in the medium suitable for diffraction purposes. The device also includes means (24) for providing a third wavefront (λ 1 ) to travel in said medium which is diffracted by the periodic refractive index variation induced by the first and second wavefronts.

摘要： interferometric multimode fiber optic switches and modulators include combinations of various components. Two electro-optical crystals (27, 37) have a dielectric beam splitting coating (48) affixed to portions thereof. The coated portions of the two crystals are juxtaposed. Means (17, 18, 19, 20, 22, 51, 52, 53, 54) are provided for varying the indices of refraction of the two crystals (27, 37) with respect to each other. Light entering into the first crystal (27) and travelling within the two crystals (27, 37) can be switched to selectively exit from one crystal (27) or from the other (37) by varying the index of refraction of one of the crystals (27, 37) with respect to that of the other. By interferometric principle of operation, the phase relation of light is transformed into spacial direction. The crystals (27, 37) can be selected from the group consisting of lithium niobate, lithium tantalate, and barium strontium niobate. The dielectric beam splitting coating (48) can be formed of multiple layers of material such as zirconium oxide and silicon dioxide. The indices of refraction of the crystals (27, 37) are varied by applying electric fields of one polarity at opposite surfaces thereof. Light enters the various crystals (27, 37), and is reflected, and is transmitted at various surfaces (31, 34, 42, 46) thereof so that, upon entering a particular area, within the crystals (27, 37), reinforcement or interference of light can occur.

摘要： An opto-electronic switch which shows a good signal rejection ratio between modes is also of particularly small dimensions. The switch comprises a semiconductor laser 1 having four contacts 12, 12ʹ, 13, 13ʹ which provide gain guiding under two stripe windows 18, 19. By varying the bias currents supplied to the individual contacts 12, 12ʹ, 13, 13ʹ, or by inputting optical control signals to the waveguiding channels under the stripe windows 18, 19, different configurations of optical output from the laser 1 can be achieved. The two contacts, 12, 12ʹ and 13, 13ʹ, associated with each stripe window 18, 19 are effectively a single stripe contact with a discontinuity. It is thought that diffractive transverse coupling at the discontinuity allows the use of a shorter device than in known directional switches. With feedback, the switch operates as a memory device. The switch finds particular application in optical communications, for instance in signal routing.

摘要： Torsional type optical ray deflection apparatus comprises a pair of etched plates (10, 20), one ofthe plates (20) is made of single crystal semiconductor material such as silicon, and the other plate (10) is of a suitable-insulating material such as glass. The semiconductor plate (20) is etched to form an elongated bar (22, 30,24) of the material having a wider central portion (30) which forms a reflecting surface armature of suitable area suspended internally of the rectangular frame formed by the remainder of the semiconductor plate. The insulating plate (10) is etched to leave an annuloidal depression (12) centrally ofthe plate. An elongated land in the centre of the insulating plate underlies the reflecting surface area (30) to support the torsion bar-reflector structure in the direction normal to the longitudinal axis while allowing rotation about that axis. Planar electrodes (14,16) are laid down in the bottom of the depression in the insulating plate for exerting an electrostatic force between one of the electrodes and the semiconductor armature, thereby causing angular displacement about the longitudinal axis of the torsion bar which will deflect rays of light incident to the reflecting surface portion.

摘要： Apparatus and method for providing an improved variable lens and birefringence compensator envisioned for use within the resonator cavity of a laser which is capable of continuous operation. A pair of cylindrical bodies of optical material (12A, B) having a temperature dependent index of refraction are thermally coupled to heat exchange means (14A, B) surrounded by potting material (16) which adds or extracts heat from the exterior surfaces of the cylindrical bodies in order to establish radially dependent thermal and stress gradients within the bodies. The heat exchange means (14A, B) is supplied power through leads (20A, B) and infuses or removes heat in order to establish a thermal gradient which is used to create a dynamic lens of opposite lens aspect to that of the laser rod which corrects beam divergence in the lased output. The stress gradient causes the compensator body to behave like a birefringent substance. The double refracting behavior of the compensator effectively reconstructs the laser beam passing through it which was depolarized by the birefringent action of the laser rod itself. The tandem arrangement (48) of variable lens and birefringence compensators is coordinated by temperature sensor and trigger means (66, 68) which sense the temperature of the compensators (50, 52) through thermocouples (60, 61) and which are coupled to heat exchange means (14A, B) via control means (70, 72) and leads (20A, 20B). The control means (70, 72) prevent the compensators from overheating and enable the lensing and compensating action to be maintained without interruption.
