Ultra-Compact Multi-Level Optical Switching with Non-Volatile GST Phase Change

We demonstrate a miniature multi-level optical switch element based on a $1\times 1$ multimode interferometer (MMI) loaded with a $0.5-\mu m$-long Ge2Sb2Te5 strip. Six-level dynamic switching is successfully demonstrated with a maximum transmission change of 15 0%.
