Abstract

Azimuthally segmented helical-ring-core waveguides (HRCWs) were fabricated in silica glass by direct laser writing. Triple-segmented waveguides provided single-mode or few-mode light guidance depending on the core diameter. Bragg resonance reflection of the light carrying orbital angular momentum (OAM) was registered confirming the generalized angular phase-matching condition, which considers the azimuthally segmented structure of the waveguides.
