New compact optical amplifier on a chip.

Caption

The new component is made of silicon nitride and consists of nine separate waveguides (left). Each waveguide is composed of 22 spirals and can amplify light by about ten times with a noise figure of only 1.2 decibels. Each spiral (right) has an area of 1 square millimeter and the shape enables the compact design of the amplifier.
