To investigate the transmission spectrum characteristics and cladding-mode coupling behavior of UV-written Bragg gratings fabricated in depressed-cladding optical fibre.
Fabricated Bragg gratings in depressed-cladding optical fibre using ultraviolet (UV) laser writing.
Measured and analyzed the experimental transmission spectra across the fundamental resonance and adjacent wavelengths.
Observed distinct fine-structure transmission features situated on the short-wavelength side of the fundamental Bragg line.
Demonstrated that these spectral features result from mode coupling between the fundamental core LP01 mode and higher-order LP0n and LP1n cladding modes.

Implication

Experimental study reveals cladding-mode coupling in depressed-cladding fibre Bragg gratings, indicating short-wavelength features arise from interactions with higher-order modes.
