The Application of Metal Deposition in Optical Sensor Technique. The Microscale Cu Deposition as “Electrochemical Welding”

Abstract

The problem of how to attach an optical glass fiber to a copper plate was solved with the use of microscale electrolyser of special design. The respective laboratory scale technology was presented. The results were documented by photos of ready elements. The matter of relation between deposition by means of constant current electrolysis without potential control and the process realized with the use of cyclic voltammetry and chronopotentiometry techniques was raised and discussed.Index Terms-Optical fiber sensor, flat diaphragm, fiber loaded diaphragm, metal deposition, solid electrodes, cyclic voltammetry (CV), chronopotentiometry (CP), packed-bed micro-electrolyser.
