INTEGRATED OPTICAL WAVEGUIDE SYSTEM

摘要

In an integrated optical channel waveguide system there is in one or there are in a number of layers, such as enclosure layers, a passive light guiding layer and an active light guiding layer, adiabatic layer thickness transition zones which are positioned next to a working zone. In this way, the relative layer thickness located in the working area, for example a sensor window, a modulation window or a light entry surface would be optimised, for example, for sensitivity, modulation voltage and loss of light power due to the incoupling without the necessity of the optical layer-thickness elsewhere in the system having to be adjusted. Incorporated in a Mach-Zehnder interferometer this results in an exceptionally sensitive and reliable sensor.
