We present and characterize a simple CO laser processing technique for the fabrication of compact all-glass optical fiber cladding light strippers. We investigate the cladding light loss as a function of radiation angle of incidence and demonstrate devices in a 400 μm diameter fiber with cladding losses of greater than 20 dB for a 7 cm device length. The core losses are also measured giving a loss of <0.008±0.006 dB/cm. Finally we demonstrate the successful cladding light stripping of a 300 W laser diode with minimal heating of the fiber coating and packaging adhesives.

The advancement of underwater monitoring technologies has been significantly hampered by the limitations of traditional electrical sensors, particularly in the presence of electromagnetic interference and safety concerns in aquatic environments. Fiber optic sensors are therefore nowadays widely applied to underwater monitoring devices. However, silicon- and polymer-based optical fibers often face challenges, such as rigidity, susceptibility to environmental stress, and limited operational flexibility.

A series of TFBGs with varying tilt angles were directly inscribed in MCFs using the Plane-by-Plane (Pl-by-Pl) method, and the writing time for a 4 mm long TFBG was only 3.60 s.

Hollow core optical fibers of numerous guiding mechanisms have been studied in the past decades for their advantages on guiding light in air core. This work demonstrates a new hollow core optical fiber based on a different guiding mechanism, which confines light with a cladding made of epsilon-near-zero (ENZ) material through total internal reflection. We show that the addition of a layer of ENZ material coating (e.

The Parallel-CLRFBGs effectively control light scattering and interference, enhancing system feedback through increased backward Rayleigh scattering. Compared to conventional axially cascaded random gratings, gratings aligned in parallel within sub-centimeter cladding improve the integration of a laser system.

Such interfaces provide significantly higher optical reflectivity to promote optical confinement. As the structures are cladding-less, VTF-LED can be processed from simpler epitaxial structures comprising a p-n junction and the multi-quantum wells, directly leading to facile fabrication and lower manufacturing costs.
