Building Blocks for Large-scale Classical and Quantum Photonics

Dr. Carlos Errando Herranz, Marie Curie Fellow, Quantum Photonics Group, Massachusetts Institute of Technology presenting live in Goergen 101

In-person in Goergen 101 and Zoom



Large-scale classical and quantum photonics promise miniaturized, efficient, and cost-effective optical systems the size of a fingertip, with a wealth of applications in communications, sensing, and computing. However, the scalability of current integrated photonic systems is severely limited by the power consumption of their reconfigurable elements and the integration of sources and detectors. In this talk I will describe our recent results towards scalable classical and quantum photonics. My talk will focus on 1) scalable reconfigurable photonics enabled by MEMS [1], 2) their integration with superconducting single-photon detectors on the same chip [2], and 3) waveguide-integrated single-photon sources in silicon at telecommunication wavelengths [3].

Dr. Carlos Errando Herranz

Carlos Errando Herranz received his Bachelor's and Master's degrees from the Universitat Politècnica deValència, Spain, and his PhD degree from the KTH Royal Institute of Technology in Sweden in 2018. He then spent a year as a postdoctoral researcher at the Quantum Nano Photonics group at KTH. Since 2020, Carlos has been a Marie Curie postdoctoral fellow at the Quantum Photonics group at MIT, and, from 2023, he is joining TUDelft and QuTech in The Netherlands as an Assistant Professor. His research interests include quantum photonics, integrated photonics, color centers, and MEMS.
