Impact of laser invention. Squeezed light and intensity interferometer.

Classical optical corpuscular theory of semiconductor laser intensity squeezed-light generator

Demonstration of a squeezed-light-enhanced power- and signal-recycled Michelson interferometer.

We report on the experimental combination of three advanced interferometer techniques for gravitational wave detection, namely, power recycling, detuned signal recycling, and squeezed field injection. For the first time, we experimentally prove the compatibility of especially the latter two. To achieve a broadband nonclassical sensitivity improvement, we applied a filter cavity for compensation...

Signal-to-noise ratio in squeezed-light laser radar.

The formalism for computing the signal-to-noise ratio (SNR) for laser radar is reviewed and applied to the tasks of target detection, direction finding, and phase-change estimation with squeezed light. The SNR for heterodyne detection of coherent light using a squeezed local oscillator is lower than that obtained using a coherent local oscillator. This is true for target detection, for phase es...

Squeezed Sates of Light

Over the past centuries, the physics community has seen much disagreement about the true nature of light. One camp of physicists, pointing to interference experiments, insisted on a wave nature; the other, citing experiments involving the interaction between light and matter, believed in a particle nature. Today, we know that both parties were right; light is an entity that exhibits both partic...
