Abstract :
A hybrid optical filter based on long-period waveguide grating and multilayer medium thin film is proposed. The effects of the transmission spectra of the filter on the amplified spontaneous emission spectrum of Er-Yb codoped phosphate glass waveguide amplifiers are discussed. It´s demonstrated that the flatness of below 0.5dB is achieved over a bandwidth of ~ 30 nm.
