TL;DR: An overview of the most recent developments and improvements to the low-loss TriPleX Si3N4 waveguide technology is presented in this article, which can be combined to design complex functional circuits, but more important are manufactured in a single monolithic flow to create a compact photonic integrated circuit.

TL;DR: It is verified that the sum of the mode profiles of all longitudinal modes is the fundamental physical function that characterizes the Fabry-Pérot resonator and generates the Airy distribution, and the Lorentzian finesse is introduced which provides the spectral resolution of the LoreNTzian lines, whereas the usually considered Airy finesse only quantifies the performance of the Fabriespheric resonator as a scanning spectrometer.

TL;DR: In this paper, a reliable and reproducible deposition process for the fabrication of Al2O3 waveguides with losses as low as 0.1 dB/cm has been developed.

TL;DR: Erbium-doped aluminum oxide integrated optical amplifiers were fabricated on silicon substrates, and their characteristics were investigated for Er concentrations ranging from 0.27 to 4.2×1020 cm−3.

TL;DR: The highest measured gain exceeds values previously reported for rare-earth-ion-doped materials by two orders of magnitude and is predicted and measured in a 47.5 at% Yb(3+) -doped potassium double tungstate channel waveguide.
