Quantum dot (QD) lasers enable intrinsically feedback-tolerant, isolator-free silicon photonic integrated circuits (PICs), eliminating the bulky optical isolators traditionally required to suppress ...
The La Jolla/Riford Library’s Saturday hours are safe for at least the next fiscal year thanks to donations from local philanthropists. Up until recently, La Jolla was among four city library branches ...
Polarization-gradient metasurface–enabled two-photon interference achieves nanoscale displacement metrology with classical-level precision using ~3% photons, enabling high-speed, low-noise, ...
