Silica glass-based fiber optic distributed meandering waveguides for integrated photonics

Abstract

Distributed meandering waveguide based fiber optic components are introduced, categorized, and numerically analyzed in the near-infrared. The building block of all meandering waveguide components is the meandering loop mirror. The other components are the meandering resonator, meandering distributed feedback structure, symmetric and antisymmetric meandering resonator, symmetric and antisymmetric meandering distributed feedback structures giving rise to transmission spectra with Lorentzian, Rabi, Fano, coupled resonator induced transparency, and winged Lorentzian lineshapes. With this variety of spectral responses, distributed meandering waveguide fiber optic components are suitable as filters, and delay line elements in fiber optic communication, and as sensor elements in fiber optic diagnostics.
