Nonlinear Thermal Drift Characteristics in Temperature-Insensitive Silicon Nitride Microring Resonators
Tiangang Zheng, Rui Yin, Jian Xin, Shuai Li et autres
The thermal drift of microring resonators is one of the key obstacles hindering their practical applications. Employing polymers with negative thermo-optic coefficients to compensate for temperature-induced wavelength shifts represents a common solution. This study utilizes polymethyl methacrylate (PMMA) to compensate silicon nitride …
