Abstract
Information modulation plays a crucial role in the contemporary development of photonic information networks. However, prevailing optical modulators exhibit challenges such as structural complexity, high cost, elevated insertion losses, and crosstalk issues in optoelectronic conversion. To address these concerns, we propose a novel all-photonic non-volatile fiber device based on Ge2Sb2Te5 (GST), integrating a dual peanut-shaped microstructure and GST. The state of GST is manipulated through external laser modulation, enabling repeatable or randomly accessible ten-level data storage. The all-photonic modulator features non-volatility, a contrast ratio of 21 dB, and repeatability (0.2 dB). Furthermore, by configuring the all-photonic modulator in both series and parallel connections, we successfully implement logical gate functions “AND” and “OR”, showcasing significant potential in information network control.
