Abstract

A photonic molecule laser is described that includes a photonic molecule waveguide coupled to a photonic molecule seeding source configured to deliver a plurality of photonic molecules. The photonic molecule waveguide includes a second dopant maintained at a population inverted state with an energy level transition corresponding to a second frequency that is an N-fold multiple of a first frequency and amplifies the number of photonic molecules via stimulated emission. The photonic molecule seeding source includes a waveguide with a first dopant maintained at a population inverted state with an energy level transition corresponding to the first frequency. A pump source is coupled to the waveguide configured to deliver a first frequency laser pulse with pulse coherence time less than the photonic molecules correlation time. Each photonic molecule includes a threshold bound state of N first frequency photons, and each photonic molecule has the second frequency.
