Tunable Laser on Silicon Photonics for Advancing Space Exploration
German researchers led by Dr. Neetesh Singh and Professor Franz Keltner have developed a high-power tunable laser based on silicon photonics. In this work, they used a large-mode-area integrated waveguide amplifier (LMA) to achieve an output power of about 2 watts. The work was published in the journal Light: Science & Applications . An integrated large mode area…
