Abstract
A method for performing a nonlinear optical operation includes pumping a laser with an optical signal at a pump wavelength and pumping the laser with an electronic or optical bias that acts as a hyperparameter, filtering out optical output at the pump wavelength so that only light at a lasing wavelength exits the laser, and collecting light exiting the laser for further optical processing or detection.
