    摘要: The fiber optical measuring device contains a fiber optical transmission line into whose input end are directed a first and a second light beam. Both light beams have wavelengths differing from each other. Associated with the output end of the transmission line is a mirror. This mirror passes the transmitted second light beam therethrough and reflects the transmitted first light beam back into the transmission line. Associated with the output end is also a sensor for measuring a physical parameter. This sensor receives the second light beam and returns a portion thereof back into the output end. This portion depends on the parameter to be measured. Arranged at the input end of the transmission line is an optical device which separates the reflected portion of the first light beam from the returned portion of the second light beam. A first optical detector transforms the first light beam portion into a first electric signal, and a second optical detector transforms the second light beam portion into a second electric signal. A signal processor determines the ratio between the second and the first electric signals. This ratio indicates the value of the physical parameter to be measured.

    摘要: A birefringent optical waveguide structure comprises at least one or more strip waveguides of a first material embedded in a cladding layer of a second glass with at least one additional layer being applied on the cladding layer. The strip waveguides have a refractive index which is higher than the refractive index of the second glass of the cladding layers and the additional layer applies a mechanical stress to the strip waveguides which has a component extending perpendicular to the strip waveguides. Preferably, the mechanical stress is formed by the material of the additional layers having a different thermal expansion coefficient and a different elasto-optical coefficient than the materials forming the cladding layer and the strip waveguides. The method of forming the device includes rapidly cooling the structure from an elevated temperature to room temperature to create the mechanical stresses.

    摘要: A device has a waveguide, such as monomode fiber, for receiving a light beam and retransmitting specific portions of the light in a reemitted beam, which reemitted beam can be moved in space. To move the reemitted beam, the device has an arrangement for moving an end portion of the light waveguide adjacent the outlet surface to change the direction of the reemitted beam. The waveguide, such as the cladded optical fiber, can be either provided with a mode stripper or is of a sufficient length so that cladding modes will be eliminated before reaching the outlet surface. To move the end of the waveguide, various arrangements, which can utilize either an electro-magnet, a piezoelectric device or other suitable movement devices, are utilized. The device usually includes outlet optics for the reemitted beam and these optics can either be a gradient lens secured on the outlet surface of the waveguide or a lens which is spaced a distance from the outlet surface.

    摘要: A device for optically connecting one or several optical emitters with one or several optical detectors of integrated circuits characterized by a substrate, a spacer disposed on the substrate providing recesses for each of the integrated circuits and components and a cover plate with either a light waveguide structure extending between the various emitters and detectors interposed either between the cover plate and spacer or on one of the cover plates and spacers or a distributing element positioned on a surface of the cover plate for distributing light emitted by the optical emitter in one recess to the detectors of the same recess or both. The waveguide system allows interconnecting an optical emitter of one unit or component with a detector of another unit component or components. The distributing element allows connecting the optical emitter to the optical detector of a single unit. Thus, selection of the two types of optical arrangements allows an external connection of one component to another component or internal connections of elements of a single component.

    摘要: A method and optical arithmetic apparatus for converting residue numbers into positionally notated numbers utilize linear periodic structures which can be shifted relative to one another, each linear periodic structure being allocated to a prime number module of those prime number modules which are utilized in the residue representation of a decimal number, with the duration of the period for a structure being proportional to the module allocated thereto. The structures may be structures for generating standing light waves. The shift of the phase positions of the light waves is undertaken by respective phase modulators with the waves being shifted out of an original phase position in accord with the allocated residue module or the sum of the modules. The decoded result is obtained by noting the values occurring at positions where the structures coincided before shifting by means of the phase modulators and which coincide after the shift.

    摘要: A device for executing a scalar multiplication of vectors is constructed in the form of an interferometric adder for residue numbers. A plurality of series-connected, vector-component-controlled phase modulators are disposed in each of the phase-modulatable light beams existing for such adder. A phase modulator is provided for each component of a vector, and which generates a phase shift as a function of the components of the vectors to be multiplied which are supplied to it. This phase shift is proportional both to the component of the one as well as to the component of the other vector. The phase shift generated by each component amounts to 2.pi. when the numerical value of the component is divisible by the corresponding module without remainder. The result of the scalar multiplication is derivable as a positionally notated number from the interference pattern or interference patterns produced after the radiation through the phase modulators.
