N2 - Temperature dependence is one of the main challenges of the silicon-on-insulator platform due to the large thermo-optic coefficient of its core material. In this work, to the best of our knowledge, we propose a design of an all-passive athermal silicon-on-insulator Mach-Zehnder interferometer (MZI) with the minimal temperature sensitivity reported to date. The MZI’s temperature compensation was achieved by optimizing the relative length of its wire and subwavelength arms and by tailoring the thermal response of the subwavelength structure. Simulations of the device performance showed that the overall temperature sensitivity of 7.5 pm/K could be achieved over a 100 nm spectral range near the 1550 nm region.
