MIT Develops Miniature Tractor Beam for Cell Capture

MIT researchers have developed a chip-based "tractor beam" that uses a focused beam of light to capture and manipulate biological particles without damaging them. This miniature device, inspired by "Star Wars," could revolutionize biological research by allowing the study of DNA, cell classification, and disease mechanisms in a sterile environment. Unlike traditional optical tweezers, this technology can manipulate particles millimeters away from the chip surface, avoiding contamination and stress on cells. The research, published in Nature Communications, was funded by the NSF and MIT fellowships.

"Revolutionizing Transmitters: Energy Efficiency Achieved with CMOS Chip and Silicon Photonics"

Researchers at the University of Southampton have developed an energy-efficient transmitter based on CMOS technology and silicon photonics. By co-designing the electrical driver amplifier and optical modulator, they achieved high data transmission rates while consuming minimal energy. The transmitter demonstrated a 112 gigabaud-112 gigabits per second on-off keying rate and a 224 gigabit per second pulse-amplitude modulation, with energy efficiency below picojoules per bit. This innovative design approach could inspire the development of similar components to enhance communication technologies.

Intel Unveils 8 Core 528 Thread Processor with Advanced Silicon Photonics

Intel showcased an 8-core processor with 66 threads per core, featuring a direct mesh-to-mesh optical fabric for hyper-sparse data processing as part of the DARPA HIVE program. The processor utilizes a RISC ISA and is packed into 16 sockets in a single OCP compute thread, leveraging optical networking for high-speed data transfer. The chips employ silicon photonics for on-die optical networking, enabling direct connections between chips without the need for switches and NICs. The power consumption is primarily attributed to silicon photonics, and the technology is being developed on TSMC 7nm.

Silicon Photonic MEMS Integration for Semiconductor Manufacturing

Researchers led by Associate Professor Niels Quack from the University of Sydney have developed a microfabrication process that combines optics and micro-electro mechanical systems (MEMS) in a microchip, enabling the creation of devices like micro-3D cameras and gas sensors for precision air quality measurement. The technology uses semiconductor manufacturing techniques to create a new, more energy-efficient generation of devices for fiber-optical communications, sensors, and even future quantum computers. The photonic MEMS are compact, consume very little power, are fast, support a broad range of optical carrier signals, and have low optical loss.
