“…At the Department of Optoelectronics at SUT for more than ten years investigations have been under way concerning magnetooptically sensitive waveguides [9][10][11][12][13][14][15][16][17][18][19]. For two years already investigations have been run concerning socalled volumetric optoelectronic sensors of the magnetic field with optical fibre inputs [16].…”

Abstract. The paper presents the experimental results of the investigations of optical fibre current sensors with an external transformation. The head of the sensor is made of the glass which has a high value of the Verdet constant. The sensor was built on the glass bar (with high value of the Verdet coefficient), polarisers, plastic optical fibres, a light source and a detector module. The paper deals with magnetic field measurements of two types of electrical current conductors: a typical conductor with circular cross-section and a busduct. Output signals from the optical current sensor were displayed on the digital oscilloscope and memorized in µComp for a further analysis. This type of sensor was investigated on a laboratory stand and on an electrical power line which included conductor where the high intensity electric current flow. The constructed optoelectronic current sensor was tested for detection of current with intensity of the order of 200 A, with an accuracy of a few percent. Practically, the upper border of the current detection by means of this sensor is much higher.

This paper presents the results of investigations concerning input-output systems of an electromagnetic wave in the visible and near visible spectrum for their application in structures of integrated optics. The input-output structures used in described planar optical waveguides are in a form of prism and grating couplers. The first part of the paper contains numerical analysis of grating couplers aiming at an optimization of their geometrical parameters, strictly — the depth of the grooves in the grating coupler. The second part presents the practical realization, as well as experimental tests of the planar optical waveguide with the hybrid input-output system. As the input system of the electromagnetic wave, a prism coupler was used, and in the case of the output system — a photonic structure with grating coupler was applied. The investigated planar wave guides with the input-output structures were made of a wide energy band gap semiconductor — zinc oxide (ZnO).

“…In this context, one of the most important problems of polarimetric sensors, which employ optical fibres, is to reduce an influence observed in them impact of random mechanical stresses on the fibers affecting the state of polarization of light propagating through the fiber [3,13,14]. To limit the effect of mechanical stresses on the polarization state, a magnetic-field sensor in a form of a bulk--glass small cylinder was designed.…”

The present paper deals with investigations concerning optical magnetic sensors. The most important advantage of sensors of this kind is their safety of service and insulating power. The insensitiveness of optical sensors to electromagnetic interference was discussed and experimentally investigated. The experimental investigations were concentrated on the adequate sensing fibre as well as on the sensor based on the bulk glass cylinder. The paper presents the results of magnetooptic tests of the elaborated magnetic field optical sensors and conclusions arise from them.
