The main goal of our research is to develop an integrated photonics circuit for sensing system based on Optical Frequency Domain Reflectometry in order to reduce size, weight and cost of current system. In this work we designed, simulated and fabricated Michelson interferometer integrating components such as adiabatic splitter, loop back mirrors, grating couplers and waveguides on total area 150x410 μm of silicon-on-insulator chip. According to simulation results free spectral range of the interferometer is 0.55 nm. Manufacturing variability was taken into account by performing corner analysis.
