Study of Integrated Optical Switch for Development of Logical Element Controlled by the Thermal Influence on Ge2Sb2Te5 Layer (GST)

The alternating phase layer Ge2Sb2Te5 (GST) demonstrates a significant refractive index difference between the amorphous (a-GST) and crystalline (c-GST) states. The fast and reversible phase transition between the two states allows for high speed and thermal stability of integrated optical devices. The paper presents a study of an integrated optical switch based on an annular microresonator with a superimposed GST layer controlled by the thermal influence. Such switches may be used in the optical circuits to implement logic functions.
