Abstract
A high-brightness squeezed light source includes a plurality of light squeezing elements and a photonic summing device. The light squeezing elements each output respective squeezed light responsive to receipt of unsqueezed light. The photonic summing device receives the squeezed light output by each of the light squeezing elements and coherently adds the squeezed light to generate a high-brightness squeezed light output. The high-brightness squeezed light output has a greater brightness than the outputs of the light squeezing elements, and a same degree of squeezing as one or more of the outputs of the light squeezing elements.
