Unique all-fiber tunable filter using a single resonant-band LPG and nanoparticle dispersed electro-optic polymer

摘要

A single resonant band, thin cladding long-period grating (LPG) is tuned using a nanoparticle dispersed electro-optic polymer. The LPG has been tuned over 10 nm and has a potential tuning range upwards of 50 nm.
