An absorption-based, fiber-optic pH meter for the physiological pH range is presented. It employs a sensor membrane based on a NIR proton-carrier dye and laser diodes as light sources. It is shown that an optical absorption sensor with a sensor dye p

A Novel Slab Model (NSM) for the modal analysis of Overlayer (OL) deposited Bent Step-Index Single-Mode Fiber (BSSF) half-couplers is presented. In this NSM the BSSF is replaced by a modal equivalent slab waveguide (ESW) structure. It is shown that w

A novel procedure of matching the modal properties of a bent step-index single-mode fiber (BSSF) by the ones of an equivalent slab waveguide (ESW) structure is presented. On applying this procedure the actual BSSF structure is modelled in the first s

An intrinsic fiber optic pH sensor based on a sol-gel immobilized acidochrmoic acridinestyrile dye is presented. The absorption maximum of the applied dye at 670 nm wavelength fits well to the emission of cheap GaAlAs laser diodes.

Coloration and luminescence of oxygenated CaF2 crystals are investigated, with the well-known UV absorption at about 210 nm being chosen as criterion for oxygen incorporation. Three groups of crystals were found, which differed relatively little as t
