Photosensitive fiber of Slanted FBG
Product code: PHOSFBG
Features
Specially designed of fiber core structure for use in slanted FBG filter
Core and Inner-cladding both have photosensitivity
Applications
◆ Gain-flattening filter for erbium doped fiber amplifier (GF-EDFA)
◆ Ultra-narrow FWHM bandwidth Slanted-FBG compared to standard single mode fiber
◆ Low back reflection Slanted-FBG
