Laser Arrays May Simplify Co-Packaged Optics
• Monolithic tunable lasers can adapt statically and dynamically. • Key Takeaways The move to co-packaged optics (CPO) holds the promise of putting photonic ICs (PICs) and electron
X-rays reveal kingfisher feather structure in unprecedented detail
• Northwestern researchers used high-energy X-ray imaging to map kingfisher feather nanostructure. • Feathers display photonic crystals-microscopic ridges on keratin strands-creati
