Scientists Achieve High Power with New Smaller Laser

The first high-powered, randomly polarized laser beam with a ”Q-switched” laser. An international team of scientists has produced the first high-powered, randomly polarized laser beam with a “Q switch” laser, which typically emits pulses of light so brief that they”re measured in nanoseconds. Lasers are a critical part of modern technology—they”re used in everything from

1.3  μM Submilliamp Threshold Quantum Dot Micro-Lasers on Si

As a promising integration platform, silicon photonics need on-chip laser sources that dramatically improve capability, while trimming size and power dissipation in a cost-effective way for volume manufacturability. Currently, direct heteroepitaxial growth of III–V laser structures on Si using quantum dots as the active region is a vibrant field of research, with the potential to
