Photonic memory Researchers from Zhejiang University, Westlake University, and the Chinese Academy of Sciences developed a 5-bit photonic memory capable of fast volatile modulation and proposed a solution for a nonvolatile photonic network supporting rapid training. This was made possible by integrating the low-loss phase-change material (PCM) antimonite (Sb2S3) into a silicon photonic plat... » read more

HBM’s Future: Necessary But Expensive
By Karen Heyman - 20 Jul, 2023 - Comments: 0

High-bandwidth memory (HBM) is becoming the memory of choice for hyperscalers, but there are still questions about its ultimate fate in the mainstream marketplace. While it’s well-established in data centers, with usage growing due to the demands of AI/ML, wider adoption is inhibited by drawbacks inherent in its basic design. On the one hand, HBM offers a compact 2.5D form factor that enables... » read more

Converting heat to electricity Researchers at the National Institute of Standards and Technology (NIST) and University of Colorado Boulder fabricated a device to boost the conversion of heat into electricity. The technique involves depositing hundreds of thousands of microscopic columns of gallium nitride atop a silicon wafer. Layers of silicon are then removed from the underside of the waf... » read more

Nanoimprint Finally Finds Its Footing
By Gregory Haley - 20 Apr, 2023 - Comments: 2

Nanoimprint lithography, which for decades has trailed behind traditional optical lithography, is emerging as the technology of choice for the rapidly growing photonics and biotech chips markets. First introduced in the mid-1990s, nanoimprint lithography (NIL) has consistently been touted as a lower-cost alternative to traditional optical lithography. Even today, NIL potentially is capable o... » read more

Transitioning To Photonics
By Karen Heyman - 13 Apr, 2023 - Comments: 1

Silicon photonics is undergoing a resurgence as traditional approaches for reducing power and heat become more difficult and expensive, opening the door to a whole new set of technological challenges and driving up demand for a skill set that is in short supply today. From a technology standpoint, photonics is extremely complex. Signals drift, they are modulated with heat, and structures lik... » read more

Challenges In Photonics Testing
By Karen Heyman - 11 Apr, 2023 - Comments: 0

Photonics is poised for significant growth due a rapid increase in data volumes and the need to move that data quickly and with minimal heat. But to reach its full potential photonics will have to overcome several production hurdles. The biggest challenge today involves alignment. While the industry is poised to produce billions of units, it still relies on testing practices that don't scale. ... » read more

Using Photonic Band Gap in Triangular SiC Structures for Efficient Quantum Nanophotonic HW
By Technical Paper Link - 03 Apr, 2023 - Comments: 0

A new technical paper titled "Utilizing photonic band gap in triangular silicon carbide structures for efficient quantum nanophotonic hardware" was published by researchers at UC Davis. Abstract: "Silicon carbide is among the leading quantum information material platforms due to the long spin coherence and single-photon emitting properties of its color center defects. Applications of silico... » read more
