Abstract:

This paper theoretically and experimentally analyzes the possibilities of quartz glass microstructures with nonhexagonal (circular) orientation of the cavities in the cladding and a 40-μm-diameter core in order to improve the weak directionality of the fundamental mode. It is established that the criterion for reaching the single-mode regime of radiation propagation is a high discrimination level of the TM₀₁ polarization component of the first upper mode.

Keywords:

microstructured lightguide, large core, single-mode regime, fundamental mode, higher mode, radiation leakage
