Abstract
This paper presents our recent developments on optical amplification in photonic chips that were developed as part of the European project OPHELLIA (On-chip PHotonics Erbium-doped Laser for LIdar Applications). A photonic chip, integrating an optical amplifier based on Al2O3:Er3+ doped with $1.5\times 10^{26}$ ions/m' over a length of 7 cm, and Si3N4 multiplexers, is shown to have an internal net gain of 20 dB on the active section and an on-chip gain of 4.5 dB at the chip output for a signal at 1550 nm. These results demonstrate the potential of this technology for developing high-performance integrated optical amplifiers.
