The Study On Micro Integrated Optical Sensor Based Mach-Zehnder Interferometer Design

: Integrated optical (IO) microsystems for interferometric analysis can be used in sensing applications playing quite different roles; in particular they can operate by detecting the transmission changes induced by some chemical or biological adsorbate coming in contact with the optical chip in a region close to an integrated waveguide and interacting with the evanescent field coupled to the waveguide. Alternatively, IO microsystems can act as transducers of the variations of the properties of an optical signal, namely the intensity, originated by the presence of chemical or biological compounds along the optical path between a light source and the IO microsystem. In particular, the integrated microinterferometer can allow the capability of performing the analyses in situ, possibly without sample manipulation and remaining almost free from the poisoning problems frequently present in other kinds of detectors for chemical compounds. This feature explains the reason why the IO microsystems for interferometric analytics are under strong consideration in many different scientific areas such as optoelectronic gate(and,or.not) in (pics), Astrophysics, Environment, Biosciences, Space Science and Exploration without mentioning the peculiar interest in the Safety and Security field.
