Realization of spectral tunable filter based on thermal effect in microfiber structure

This paper demonstrates a new approach for tuning the extinction ratio of a complex microfiber structure output using thermal effect. The microfiber filter device comprises of a microfiber Mach-Zehnder interferometer followed a knot structure, where temperature is controlled by a DC current applied...
