An Open-Source Multi-functional Testing Platform for Optical Phase Change Materials
Cosmin-Constantin Popescu, Khoi Phuong Dao, Luigi Ranno +18
Owing to their unique tunable optical properties, chalcogenide phase change materials are increasingly being investigated for optics and photonics applications. However, in situ ch…
Nonvolatile Tuning of Bragg Structures Using Transparent Phase-Change Materials
Nicholas A. Nobile, Chuanyu Lian, Hongyi Sun +7
Bragg gratings offer high-performance filtering and routing of light on-chip through a periodic modulation of a waveguide's effective refractive index. Here, we model and experimen…
Toward accurate thermal modeling of phase change material based photonic devices
Kiumars Aryana, Hyun Jung Kim, Cosmin-Constantin Popescu +5
Reconfigurable or programmable photonic devices are rapidly growing and have become an integral part of many optical systems. The ability to selectively modulate electromagnetic wa…
Multi-material heterogeneous integration on a 3-D Photonic-CMOS platform
Luigi Ranno, Jia Xu Brian Sia, Khoi Phuong Dao +1
Photonics has been one of the primary beneficiaries of advanced silicon manufacturing. By leveraging on mature complementary metal-oxide-semiconductor (CMOS) process nodes, unprece…
