1. Quantinuum eyes $10B IPO: What’s its potential impact on the quantum industry?
A $10B IPO for Quantinuum may catalyze growth within the quantum sector, spur more investment, and bring quantum computing into the spotlight.
2. Co-packaging photonics and electronics poses challenges
At IEEE’s 74th Electronics and Components Technology Conference (ECTC), Keren Bergman gave a keynote address about different techniques and approaches to bring photonic chips closer to the electrical side, compute and memory, and other components at the edge of the computing system—and we got a chance to chat with her.
3. Optics industry addresses the germanium issue
Potential supply issues have optics manufacturers and the U.S. government looking at alternative materials to head off disaster.
4. In-package optical interconnects enable new generative AI architectures
An information superhighway of sorts—in-package optical I/O—can keep AI traffic flowing quickly and efficiently.
5. Seeing is believing with today’s CMOS image sensor technology
A new type of CMOS image sensor applies lateral overflow integration capacitor (LOFIC) to 2.1 µm pixel-generation automotive applications to enhance HDR images and mitigate LED flicker in virtually any lighting conditions. LOFIC has also been applied to smartphone CMOS image sensors to enhance performance in all lighting conditions.
6. Hollow-core fibers revolutionize green laser technology
Researchers made a significant breakthrough in laser and fiber technology, which showcases the potential for the long-distance fiber delivery of high-power green laser pulses via hollow-core fibers, a revolutionary new type of optical fiber.
7. Ti:sapphire lasers go chipscale
A titanium-sapphire laser on a chip is a huge technology disruption for photonics in terms of scale, efficiency, and cost. Bonus: No moving parts means it can be mass-produced.
8. Femtosecond vs. nanosecond laser damage threshold
Understanding laser damage mechanism differences between femtosecond and nanosecond lasers promotes efficiency and longevity of laser systems.
9. U.S. Naval Research Lab explores cold-atom quantum inertial sensors for navigation
A high-performance cold-atom quantum interferometer mitigates a scattered light issue and may significantly enhance military inertial navigation systems.
10. Nonlinear optics for quantum transport?
What happens when you replace linear optics with nonlinear optics for teleportation? You get a new quantum transport method that doesn’t require a bunch of extra photons.
