💡 Researchers at UC Berkeley and Berkeley Lab have developed a new method to power nanophotonic lasers with electricity without disrupting their light-controlling structures.

💡 This breakthrough, reported in Nature Nanotechnology, uses an architecture called "orthogonal optoelectronics" to independently engineer electrical pathways and optical modes, solving a long-standing conflict between good optics and good electrical injection.

💡 The team developed a monolithic fabrication process for hundreds of nano-post electrical contacts, placed at points where the light's electromagnetic field is zero, making them electrically conductive but invisible to light.

💡 Uniformity in nano-post fabrication was found to be critical for even current injection across the device, highlighting the need for co-design of optics, electronics, and nanofabrication in future devices.
