Multi-objective design of photonic devices and metamaterials
Université Paris-Saclay, France
High performance and large-scale integration are driving the design of innovative photonic devices based on non-trivial shapes and metamaterials. In this scenario, multiple figures of merit must necessarily be considered in the evaluation of the device performance, e.g., losses, bandwidth, footprint, or tolerance to fabrication uncertainty. In this invited talk we will present our recent work on the use of machine learning and optimization tools for the development of photonic components with high performance and advanced functionalities.

Ultra-dense interferometric chain architecture for datacom and telecom applications
Serge Bidnyk, Ksenia Yadav, Ashok Balakarishnan
Enablence Technologies Inc., Canada
Further increase in the density of integrated planar lightwave circuits (PLCs) depends on the introduction of compact guided-wave layout solutions. We describe a novel architecture for coiling multistage interferometric devices with densities reaching the theoretical limit. Our approach is validated by the design, fabrication, and deployment of state-of-the-art PLCs based on the proposed architecture for use in datacom and telecom applications.

In this paper, we present the generation of supercontinuum in ultra-low loss silicon nitride waveguides fabricated in 200mm wafer. The waveguide was pumped at its maximum group velocity dispersion(GVD) wavelength. Both experimental and simulation results are presented and compared. We observed a rather flat and symmetric spectrum expansion over 1.3 octave from visible to near IR wavelength range with a pump pulse energy lower than 65pJ.

We demonstrate epitaxially grown semiconductor membrane quantum well lasers on a SiO2/Si substrate lasing in a waveguide configuration, for potential uses as coherent light sources compatible with photonic integrated circuits. We study the emission characteristics of In0.13Ga0.87As/GaAs0.94P0.06 quantum well lasers, by using real and reciprocal space imaging. The laser cavity length is 424 μm, it emits light at 1 μm, and lasing thresholds as low as 211 mW were recorded. Control over the position and size of the laser spots by the pump was also observed and demonstrated.
