Abstract

We report on the generation of cw squeezed vacuum states of light at the telecommunication wavelength of 1550 nm . The squeezed vacuum states were produced by type I optical parametric amplification in a standing-wave cavity built around a periodically poled potassium titanyl phosphate crystal. A nonclassical noise reduction of 5.3 dB below the shot noise was observed by means of balanced homodyne detection.
