As the worlds of advanced semiconductor packaging, optics, photonics, and networking converge to accommodate the performance needs of high-performance computing, AI data centers, and quantum computing, it’s becoming essential to combine optical and electrical functions within the same package, a.k.a. copackaged optics. Why turn to copackaged optics with silicon photonics as a solution? It accommodates bandwidth density and energy efficiency challenges.

In this episode of Photonics Hot List:A new approach involving noninvasive functional near-infrared spectroscopy, designed to study the developing newborn child brain, has discovered that infants may begin learning even before birth. Optics manufacturer Gooch & Housego is expanding its presence in the military and defense sector via the recent acquisition of a thin-film coatings developer. Gooch & Housego is expanding overall, too, with the opening of its Innovation Hub for Life Sciences.

A recent collaboration led by University of Innsbruck researchers in Austria revealed that hot (alive) Schrödinger cat states can indeed be created within a superconducting microwave resonator—and it means quantum phenomena can be generated and used within less perfect and warmer conditions than previously believed.

A team from Vivid Photonics—a spinoff of Tyndall National Institute and the Research Ireland Centre for Photonics—has developed horizontal-cavity surface-emitting superluminescent diodes (SLDs) to significantly boost image quality for augmented and virtual reality applications (see video). These novel light sources combine the characteristics of both lasers and light-emitting diodes (LEDs). “This is an advance in photonics,” says Muhammet Genc, CTO of Vivid Photonics.
