Achieve Unprecedented Linewidth Narrowing with On-Chip Self-Injection Locked Lasers
A team of researchers from the Massachusetts Institute of Technology (MIT) has developed a new on-chip laser technology that significantly reduces the amount of light that is lost or scattered when light is emitted from a laser. The new technology, called “self-injection locking,” is capable of reducing the linewidth of the laser to less than one-tenth of its original value. This breakthrough could lead to more efficient on-chip lasers that are more suitable for use in a range of applications, such as communications and sensing.
