Ultra-sensitive long period fiber gratings for broadband modulators and sensors

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate long-period gratings whose attenuation can be changed by 25 dB in a 48-nm spectral band, with ambient index changes of only 2.7×10−4. This is achieved by inducing coupling to ultra sensitive cladding modes in engineered fiber waveguides.
