摘要: Utilizing a recently developed two-step fabrication process, we have experimentally demonstrated what is to the best of our knowledge first ever integrated antiresonant reflecting optical waveguide (ARROW), directly inscribed into bulk glass. The consists an array high-index contrast rods that surround unmodified core. transmission spectrum reveals formation discrete bandgaps can be tuned by varying diameter individual rods.
