With chip containing eight Raman lasers, Intel aims to cut down on the cost of optical technology.
Raman lasers on an Intel chip
Intel researchers have developed the world's first silicon chip capable of producing a high-quality continuous laser beam. Eight lasers are built into a single silicon chip.
Light is amplified inside the chip, and a laser beam exits through the thin optical fiber on the right. Two slender metal probes activate an electronic device, which removes excess electrons, enabling the laser to emit a stream of light.
