No slowdown: Philips is continuing to expand VCSEL production
Philips Photonics says that the proliferation of applications for vertical-cavity surface-emitting lasers (VCSELs) in 3D and proximity sensing means it has now passed the shipment milestone of one billion such devices.

Scientists at Dongguk University have found a way to create printed p-channel thin-film transistors by using the abundantly available and environmentally-friendly copper(I) iodide semiconductor at room temperature. Their energy-efficient and cost-effective fabrication method for these transistors may pave the way for developing low-cost and novel optoelectronic devices.
