High-Resolution Interferometric Temperature Sensor Based on Two DFB Fiber Lasers with High-Temperature Monitoring Potential

A high-resolution temperature sensor using the beat frequency measurement between the modes of two DFB fiber lasers is presented. The laser cavities are formed by the femtosecond inscription technique in a highly Er/Yb co-doped phosphosilicate fiber with low optical losses and compact design. The ex...
