Low-Loss Switchable Topological Photonic Crystal

ArXiv

Analysis

This paper presents a significant advancement in reconfigurable photonic topological insulators (PTIs). The key innovation is the use of antimony triselenide (Sb2Se3), a low-loss phase-change material (PCM), integrated into a silicon-based 2D PTI. This overcomes the absorption limitations of previous GST-based devices, enabling high Q-factors and paving the way for practical, low-loss, tunable topological photonic devices. The submicron-scale patterning of Sb2Se3 is also a notable achievement.
Reference

““Owing to the transparency of Sb2Se3 in both its amorphous and crystalline states, a high Q-factor on the order of 10^3 is preserved-representing nearly an order-of-magnitude improvement over previous GST-based devices.””

ArXiv

Analysis

This paper presents a novel synthesis method for producing quasi-2D klockmannite copper selenide nanocrystals, a material with interesting semiconducting and metallic properties. The study focuses on controlling the shape and size of the nanocrystals and investigating their optical and photophysical properties, particularly in the near-infrared (NIR) region. The use of computational modeling (CSDDA) to understand the optical anisotropy and the exploration of ultrafast photophysical behavior are key contributions. The findings highlight the importance of crystal anisotropy in determining the material's nanoscale properties, which is relevant for applications in optoelectronics and plasmonics.
