Abstract EN
An optical amplifier based on a tapered fiber and an Er3+-doped chalcogenide microsphere is designed and optimized.
A dedicated 3D numerical model, which exploits the coupled mode theory and the rate equations, is used.
The main transitions among the erbium energy levels, the amplified spontaneous emission, and the most important secondary transitions pertaining to the ion-ion interactions have been considered.
Both the pump and signal beams are efficiently injected and obtained by a suitable design of the taper angle and the fiber-microsphere gap.
Moreover, a good overlapping between the optical signals and the rare-earth-doped region is also obtained.
In order to evaluate the amplifier performance in reduced computational time, the doped area is partitioned in sectors.
The obtained simulation results highlight that a high-efficiency midinfrared amplification can be obtained by using a quite small microsphere.
