abstract
Mach-Zehnder interferometer photonic circuits are widely used in optical sensing. An important application of the Mach-Zehnder photonic circuit in particular that we envision is the detection of bio-molecules. The cause of perturbation is proposed to be a liquid crystal cavity sensitive to biological specimen. Liquid crystal materials with their birefringent properties and bulk reorientation due to surface effects are interesting for bio-sensing applications [1, 2]. Liquid crystal molecules tend to align planar at a liquid crystal/water interface. By adding small amounts of phospholipid mixtures to the water, the orientation evolves to homeotropic alignment. This process is reversible. In order to use this process as a detection method, the liquid crystal is deposited into the holes in one branch of the Mach-Zehnder device and a fluid (e.g. water) covers the entire surface of the hole through a micro fluidic channel. Compatibility of liquid crystal with glass fiber and the integrated photonic circuits are the advantages that come together in a Mach-Zehnder fabricated on a glass substrate. The technical steps of design and fabrication and the full-wave analysis of the structure using finite difference time domain (FDTD) method is presented.
