Active optical device using phase change material
… The present disclosure relates to active optical devices using a phase change material. …
Also, it is reported that the transition of the refractive index due to the phase change occurs
within less than about 500 fs. The phase change material described above may be used in an
active optical device capable of variously and quickly modulating properties of incident light. …
