    3D-Printed Polymer Wires Enhance Quantum Light Technology

    May 21, 2025

    JQI Fellow Kartik Srinivasan and his colleagues have introduced an innovative method for improving single-photon collection—an essential step in advancing secure communications, high-precision imaging and quantum computing. By integrating new fabrication techniques, the research teams demonstrated a scalable and highly adaptable approach to guiding single photons efficiently into optical fibers.

    Tiny New Lasers Fill a Long-Standing Gap in Visible-Light Colors, Opening New Applications

    September 3, 2024

    It’s not easy making green. For years, scientists have fabricated small, high-quality lasers that generate red and blue light, but the same method hasn’t worked as well in building tiny lasers that emit green light. Green laser pointers have existed for 25 years but only produce light in a narrow spectrum of green and are not integrated in chips. Researchers refer to the dearth of stable, miniature lasers in this region of the visible-light spectrum as the “green gap.” Now a team led by JQI Fellow Kartik Srinivasan has closed the green gap by modifying a tiny optical component: a ring-shaped microresonator, small enough to fit on a chip.
