High Index Contrast Subwavelength-scale Optofluidic Waveguide in MOFs

Abstract

Microstructured optical fibers (MOFs) have been widely utilized for optofluidic
waveguides, in which the micro-holes along the MOFs act as microfluidic channels for various applications such as supercontiuum sources and aqueous solution sensors. The air hole diameter of MOFs is generally several microns to tens of microns, which is much smaller compared with traditional fluid-core fiber waveguide. However, for specific applications such as ultra-trace analysis and low-threshold fluidic lasers, this channel dimension is still relatively large. The slot waveguide could confine light in a subwavelength-scale channel, however, the short propagation length and high loss of the waveguide may limit its applications.
