Due to the reduced electron states, quantum dot is beneficial in broadening the gain spectrum and lowering the noise figure. Combining this with a multi-section structure drastically improves the gain equality among the different bound states, leading to an increase in the maximum output power and an improvement of the noise figure.展开更多
We report fabrication and modeling of a fiber half-coupler based gain-flattening device for EDFA. Using such a device, flattening of the ASE spectrum of an EDFA is also demonstrated.
