A method for manufacturing an optical waveguide, in which a waveguide structure including a waveguide layer of ZnS&#x2014;SiOis deposited on a first layer, wherein a first refractive index of the first layer is lower than the refractive index of the waveguide layer. A sensor arrangement includes a planar optical waveguide, a light source, a sensor, an application unit for applying an analyte on top of the planar waveguide and a processor connected to the sensor.

Method for manufacturing an optical waveguide, optical waveguide, and sensor arrangement

The current invention is directed to a method and optical storage media reading device for restoring data stored along a data storage path of an optical storage media, the data being stored on the optical storage media and being at least in part unreadable by a conventional optical storage media reading device due to chemical or physical changes within a recording layer or a reflective layer of the optical storage media. The method and device includes detecting deformations of a shape of a groove and lands of the groove extending along the data storage path, the deformations having been generated by a laser beam during a recording process of the optical storage media, and determining the data to be restored from the detected deformations and lands.
