MIT Demonstrates First Room-Temperature, Electrically Pumped Polariton Laser**\n- On April 8, 2026, researchers at the Massachusetts Institute of Technology (MIT) published a study in *Nature Photonics* detailing the development of a polariton laser that operates at room temperature with electrical pumping. Unlike conventional lasers that rely on electron-hole recombination, this device uses exciton-polaritons in a perovskite-based microcavity, reducing energy thresholds by over 100-fold. The device achieved lasing at 295 K and required only 0.3 mW of input power. The breakthrough could enable ultra-low-power photonic integrated circuits.\n- Source: Nature Photonics, DOI: 10.1038/s41566-026-01382-1 (Published April 8, 2026)*\n- 2. University of California, Santa Barbara Achieves 1.5 Terabit/s Data Transmission with On-Chip Frequency Combs**\n\n## Analysis\nA team led by Dr. John Bowers at UC Santa Barbara announced on April 6, 2026, a new on-chip silicon nitride frequency comb enabling data transmission at 1.5 terabits per second across a single optical fiber. The comb, fabricated using CMOS-compatible processes, supported 150 wavelength channels spaced at 10 GHz. The system demonstrated error-free transmission over 80 km, marking a 50% improvement in bandwidth efficiency over prior integrated solutions. The work was presented at the Optical Fiber Communication Conference (OFC) 2026 in San Diego.\n\n*Source: OFC 2026 Technical Digest, Paper Tu5A.4 (April 6, 2026); https://www.ofcconference.org/2026*\n\n**3.
