We report on the experimental generation of entangled states of light between the wavelengths 810 and 1550 nm in the continuous variable regime [1]. The fields were produced by a type I optical parametric oscillator operating above threshold. Balanced homodyne detection was used to detect the non-classical noise properties, while filter cavities provided the local oscillators by separating carrier fields from the entangled sidebands. We were able to obtain a conditional variance based measure of I = 0.82, where values below unity demonstrate inseparability.
