We propose and demonstrate a method to compensate insertion losses in Si photonics devices based on ring resonators fabricated in SOI foundries, with no additional chip area used. It consists in the employment of Er:Al2O3 as the upper cladding layer

Damming rivers to generate electricity creates a lentic environment that favors methylmercury (MeHg) formation. Reservoirs in the Amazon are critical environments for MeHg formation, considering its old soils and the use of Hg in gold mining in the r

We propose the use of photonic molecules, i.e., coupled silicon ring structures, with triplet resonances for enhancing the delay-bandwidth product for analog modulation. We have designed a photonic molecule, composed of a 20 um radius outer ring reso
