 This paper presents a novel approach for programming photonic integrated circuits using a shellcogenide material called SB2S3. The material has been used to create a wide band gap PCM which can be programmed quickly and efficiently. This material has been shown to have low loss, high extinction ratio, high cyclicality, and 5-bit operation. Additionally, it can be programmed through on-chip silicon pin diodes, resulting in a programming energy density of 917,210 fj Nm3. Furthermore, the material can be programmed into fine intermediate states by applying multiple identical pulses, allowing for controllable multi-level operations. Finally, dynamic pulse control was used to reduce random phase errors in a balanced Mach-Zender interferometer. This article was authored by Rui Chen, Shuo Ran Fang, Christopher Perez, and others.
