Abstract
The paper presents an analysis of planar broadband waveguide interferometers in the case of a change in layer thickness. The analysis was performed for the wavelength range of 450nm-1200nm. The TE0 and TM0 orthogonal modes which propagate in this wavelength range are considered. At the output of the system, an interference signal behind a polarizer can be recorded. If a spectrometer is used as a detector, the recorded signal is a function of the wavelength. Change in the change thickness of the waveguide layers results in a change of the recorded signal shape.
期刊介绍：
Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
