42.5dB of low loss optical gain has been demonstrated in a CMOS waveguide at wavelengths around 1,500nm. Key to the achievement is a parametric amplifier architecture using a silicon nitride waveguide with far higher silicon content than usual – Si7N3. “We have developed an optical amplifier which is able to amplify light by 17,000 times at ...
