Description

<p>Alongside a summary of the field, I will present our results in high-bandwidth and low-voltage<br>(100 GHz, 1-2 V) electro-optic modulators, efficient (~1000 %/W) wavelength conversion between<br>NIR and telecommunications bands, and bright and nearly-ideal parametric photon-pair sources<br>using thin-film lithium niobate integrated with silicon and/or silicon nitride photonics.<br>These high-performance devices cannot be achieved in conventional silicon photonics. Our results<br>are recent outcomes of high-risk, high-reward projects (including international collaborators)<br>which benefit from a study of hybrid materials, cross-disciplinary device design, and innovative<br>fabrication of microchips leveraging the capabilities of both foundries and universities, and have<br>been published in major journals such as Optica and Physical Review Letters, and the postdeadline<br>papers of the OFC and CLEO conferences.<br>Bio: Shayan Mookherjea received the BS degree with honors from Caltech, the SM degree from<br>MIT, and the PhD from Caltech in Electrical Engineering with a minor in Physics. He is a Professor<br>of Electrical and Computer Engineering at the University of California, San Diego (UCSD). He leads<br>the Integrated Photonics Group at UCSD and is a Fellow of the Optica (formerly OSA) since 2013.</p>
