Abstract

A fiber design is proposed that addresses bend loss, high power and handleability concerns for fibers deployed in high power devices and associated pigtails. If bending is tight enough to leak power from the core into the glass cladding, a coating with a sufficiently low index traps this potentially dangerous power in the cladding. The coating is also designed to keep cladding power from damaging downstream devices and terminations. Loss due to tight bends is minimized by use of a glass design with a small mode-field diameter. This glass design further suppresses the high power failure mode. Over the high power coating is a thick layer of a toughened polymer coating which provides a significant increase in mechanical protection over most commercial coatings.
