High Gain Quantum Dots Fiber Amplifier over O-band Based on Tapered Fiber Coupler

Not Accessible

Your library or personal account may give you access

Abstract

An O-band Quantum Dots fiber amplifier based on tapered fiber coupler coated with PbS QDs-doped film was proposed. A maximum signal gain of 24 dB at 1310 nm with 100 nm bandwidth was obtained experimentally.
