Abstract :
A compact long-period grating (LPG) module with multiattenuation peaks has been successfully developed. The module has a simple design and is based on exploiting the coupling between the core mode and the different cladding modes for each peak. 43 mm long LPG modules have been fabricated and their temperature dependence measured
