Abstract

A novel diffractive-pumping scheme is proposed to improve the evanescent amplification using blazed fiber grating for the first time. We also investigate the cw-pumped evanescent amplification at 1.55 μm wavelength with the relative optical gain pumped at 1480 nm of around 2 dB based on side-polished fiber with the effective interaction length as long as 16 mm and with a heavily Er3+-doped (NEr3+ > 1.19 × 10 21 ions/cm3), low refractive index (n1550 < 1.47) glass overlay, which has no concentration quenching (τf = 9.0 ms).
