Abstract
The Al2O3 waveguide platform is an excellent candidate for monolithic and scalable fabrication of waveguide amplifiers. After successful demonstrations of sputter-deposited waveguides doped with Er3+, Yb3+ and Tm3+ ions, gain in the O-band is sought by means of Nd3+ ions, which form a four-level gain medium at a wavelength of 1330 nm. Preliminary results have shown on-chip gain of approximately 17 dB in a 7.52 cm long channel waveguide at 1064 nm. In this work, the optimization of Nd3+ doped Al2O3 optical waveguides to achieve net gain in the O-band is discussed.

Bjorn Jongebloed completed his Bachelor of Science in Applied Physics at the University of Twente, the Netherlands, in 2019. Shortly after, he continued with a Master of Science at the University in Twente, specializing in Applied Nanophotonics. During this time, he joined the Integrated Optical Systems group to work on evanescent field exceptional point biosensors. Bjorn is currently a PhD candidate in the same group, working on the design and characterization of a variety of photonic integrated devices. All these devices are used to demonstrate how to add functionalities to aluminium oxide waveguides.
