Résumé

Chemistry Chemistry, Multidisciplinary Chemistry, Physical Materials Science Materials Science, Multidisciplinary Nanoscience & Nanotechnology Physical Sciences Physics Physics, Applied Physics, Condensed Matter Science & Technology Science & Technology - Other Topics Technology
Hybrid silicon nitride (SiN)-quantumdot (QD) microlasers coupled to a passive SiN output waveguide with a 7 mu m diameter and a record-low threshold density of 27 mu J cm(-2) are demonstrated. A new design and processing scheme offers long-term stability and facilitates in-depth QD material and device characterization, thereby opening new paths for optical communication, sensing, and on-chip cavity quantum optics based on colloidal QDs.
