Modulation of Q Factor and Fano Lineshape in Ge<sub>2</sub>Sb<sub>2</sub>Te<sub>5</sub>-Based Grating Structure

Modulation of Q Factor and Fano Lineshape in Ge<sub>2</sub>Sb<sub>2</sub>Te<sub>5</sub>-Based Grating Structure

In this paper, the modulation of the Fano resonance (FR) of dielectric grating has been demonstrated by controlling the crystallization fraction of phase change material film. We analyze the optical characteristics of the grating structure thoroughly by the energy band structure, Q factor, and the e...
