Photonics Focus vol. 6 issue 2

March/April 2025 | Vol. 6 | Issue 2

This issue of Photonics Focus explores the ever-shrinking world of microelectronics. One story highlights how researchers are moving beyond Moore's Law with an expectation that, by 2030, they will be able to fit 1 trillion devices on a silicon wafer. Another feature looks at astronomers' plans to search for Earth-like planets with tiny deformable mirrors. A third story looks at the bright promise for VCSELs (vertical cavity surface emitting lasers) to move beyond their great sucess as data center interconnects.

The trend of ever-increasing transistor counts will continue beyond today's 100 billion transistors on a single piece of silicon to perhaps more than 10 times that number within this decade.
Photonics aids the march of Moore's Law
Tiny deformable mirrors stand out as a great option to assist in the search for other habitable worlds in the Universe.
Searching for new Earths with micro-electromechanical systems
Applications like artificial reality/virtual reality are driving VCSEL research.
VCSEL's star still shining bright
