This is the final report for the Mach-Zehnder interferometer device with both simulated results and experimental results. The pdf of this report can be found at https://upload.siepic.ubc.ca/uploads/EBeam_JamesClay.pdf
In an attempt to combat the end of Moore’s law and address the breakdown of Dennard scaling, emerging technologies such as silicon photonics have been proposed (Markov 2014). Among the many building blocks of a silicon photonic circuit, the Mach-Zehnder interferometer provides an excellent first step and learning experience in the simulation and design of a silicon photonic system (Zetie 2000)(Chrostowski 2015). A Mach-Zehnder interferometer (MZI) deduces “interference by division of amplitude” (Zetie 2000). Stated another way: a MZI is an interferometer (a device that creates and measures the results of wave interference) that first splits a single light source and then combines the resulting outputs. A more detailed explanation of the MZI and its operation can be found in the theory section below. MZI devices have many uses such as studying various aspects of quantum mechanics (entanglement, neutron diffraction) as well as being employed in electro-optic modulators.
This particular design creates MZI’s of differing lengths 100, 200, 300, and 400. For lengths of 100, 200, and 300 the MZIs have been reproduced three times.
