Polymer based Mach-Zehnder interferometer for on-chip applications

Point-of-care diagnosis leads to integration of sensors, electrical and optical components in one device and stimulated the area of lab-on-a-chip (LOC) devices where all operations and analysis are realized on a single chip. In LOC applications, the optical components based on interference principles play also important role. The Mach-Zehnder Interferometer (MZI) is well-known photonic device from on-chip applications, especially used in the field of silicon photonics. We proposed design of symmetric MZI based on polymer IP-Dip. Prepared MZIs with interrupted gap in sensing arm were proposed for high sensitive refractive index change detection. The MZIs were realized by laser lithography and optically investigated of different concentration of sucrose/water solutions.
