研究目的
Investigating photonic crystal membrane platforms for designing high-quality factor nanocavities and efficient planar waveguides to realize asymmetric Fano resonances suitable for optical switching applications.
研究成果
The experimental results demonstrate that Fano resonances in nanophotonic structures offer several advantages for realizing ultra-low power all-optical signal processing. The devices are compact and can be integrated with standard photonic circuit elements, with energy consumptions as low as 60 fJ/bit for wavelength conversion and OTDM demultiplexing, 11 fJ/bit for nonreciprocal transmission, and 1 pJ/bit for self-pulse carving.
研究不足
The study focuses on the InP-Si system without the gain medium, which may limit the applicability in systems requiring semiconductor gain materials. Additionally, the energy consumption, although low, may need further optimization for certain applications.
