报告摘要:
Photonic crystal fibers (PCFs), which are also named micro-structured optical fibers or holey fibers, represent one of the most active research areas today in the field of fiber optics. PCFs have wavelength-scale microscopic structure that runs along the entire fiber length. This structure enables light to be confined in the 2D photonic crystal by novel mechanisms.
In this talk, I will introduce different light guiding mechanisms of PCFs and their main applications, and their challenges in practical applications: low-loss splicing between different PCFs and conventional fibers. Another interesting nano-structured silica material is aerogel, also named “soid air” for its extremely low refractive-index, less than 1.05. I will also introduce micro/nano tapered fibers embedded in aerogel for different applications.
