Poster Presented in the 25th Annual Symposium of the IEEE Photonics Benelux Chapter 2021 titled ‘Gain simulation of erbium-doped Al2O3 waveguide amplifiers for LiDAR applications’ by Carlos Eduardo Osornio Martinez et. al. on 25th November 2021 in Mons, Belgium.

Abstract:

Photonic integrated circuits (PIC) based laser sources are of great interest for LiDAR applications. PICs play a crucial role for the fabrication of high performance, low cost and low size LiDAR tools. In the Ophellia project (On-chip Photonics Erbium-doped Laser for Lidar Applications) the development of Er3+:Al2O3 waveguides with low background loss and high gain per unit length is proposed to fabricate on-chip amplifiers. In this work, a three-level rate-equation model, which incorporates the quenching effects of the Er3+ ions, is used to calculate the optical gain of the integrated amplifiers. The gain for three different waveguide cross-sections, namely,  fully etched, ridge, and inverted strip loaded are compared. Simulation results show >25 dB gain for a fully-etched waveguide with cross-section of 800 nm x 1200 nm.
