    Abstract: A reverse (Alpha) (Beta) optical switch employs spatial tapering of the distance (D (2)) between a pair of optical waveguides (10, 11) for efficient straight-through transmission. Appropriate choice of effective coupling strengths for the TE and TM polarization modes achieves efficient crossover transmission. A split electrode configuration (13, 14, 15) permits the application of uniform electric fields (V1=V2) or reversed electric fields (V1=-V2) across the waveguides.

    Abstract: A resonant optical modulator includes an electro-optical substrate, an optical waveguide formed in the substrate and having a variable index of refraction, and an active modulator electrode formed on the substrate in relation to the waveguide to effect electro-optical variation of the index of refraction upon application to the electrode of a modulating signal. An interface port formed on the substrate provides the modulating signal to the electrode from a signal source and has an impedance. An electrical structure, formed on the substrate and coupled to the interface port and the electrode, makes an impedance of the optical modulator substantially equal to the impedance of the signal source. The electrical structure includes a delay line and a stub formed on the substrate.

    Abstract: A directional coupler type optical function element with a high extinction ratio, in which a junction of a 2-input/2-output directional coupler or 1-input/2-output directional coupler, formed of a semiconductor or dielectric, is formed by successively optically connecting, from the input side to the output side, a front-stage partial junction, front-stage partial junction with electrode, central partial junction, rear-stage partial junction with electrode, and rear-stage partial junction, each having a predetermined length. The connection state at the front-stage partial junction and an incidence-side lead section optically connected thereto and the connection state at the rear-stage partial junction and an emergence-side lead section optically connected thereto cancel each other, thereby equivalently providing a symmetrical connection state and preventing the extinction ratio for a cross mode from lowering. Moreover, by forming the central partial junction with a proper length, the extinction ratio for a through mode can be kept high enough. Thus, high extinction ratio characteristics can be enjoyed for both of the cross and through modes.

    Abstract: An optical directional coupler with amplification having first, second and third waveguides respectively intended for incoming light for bar coupling of light from the first waveguide and for cross coupling of light from the first waveguide. The waveguides are transparent to the wave length of the incoming light and have a characteristic refractive index in the coupling area. The coupler also includes waveguide sections constituting coupling elements for the first, second and third waveguides as well as electrodes. An arrangement is provided for achieving optical amplification of light passing through the first and the second waveguide in the bar coupling state of the directional coupler and amplification of the light passing through the first and the third waveguides in the cross coupling state of the directional coupler by feeding a current to the electrodes according to which coupling state is desired.

    Abstract: A controllable integrated optical component comprises a substrate having electro-optical properties into which optical waveguides are introduced and given which metallizations in the form of a plurality of electrodes which are chargeable with electrical voltages are applied on or next to the optical waveguide. This, a coplanar microwave line is exposed next to the optical waveguides, whereby respectively one electrode is electrically connected to respectively one strip of the microwave line and should also enable a reproducible microwave mode even for microwave frequencies that are as high as possible. The electrodes are disposed between the strips of the microwave line. When the connecting lines between the electrodes and the strips of the microwave line are strip lines, the integrated optical component can be manufactured in planar technology. Fabrication is thereby significantly simplified.
