Compound Semiconductor features “Narrowing the linewidth of the green laser”

​​“Researchers from King Abdullah University of Science and Technology, Saudi Arabia, claim to have produced the first InGaN-based green laser with a distributed feedback (DFB) grating.”

“The addition of this grating creates a single-wavelength source that could benefit sensing, atomic clocks, and underwater wireless optical communications, according to the team spokesman Boon Ooi.”
