Caption

The integrated large mode area-based amplifier amplifies a tunable seed source to a few watts level. In this scenario, the seed and the pump are fully integrated together with the amplifier on to a silicon photonics platform. The device is deployed on a satellite orbiting a planet in or outside our solar system and generates high power light around 1.9 μm to map out the chemical make up of the atmosphere of the planet. The inset shows a large mode region in the amplifier where the mode is 10s of μm2 which allows large energy extraction from the silicon photonics based LMA amplifier.
