We experimentally show that the use of shaped pulse as local oscillator in homodyne detection allows us efficient squeezing detection with near-unit mode-matching efficiency. Classical parametric gain of the shaped pulse was also investigated a deamplification gain of -12.1 dB was observed with the amplification gain of only +13.8 dB. Squeezing of -4.1 dB was directly measured using the shaped local oscillator. We report on the generation of quadrature squeezed light at 1.535 µm via single-pass optical parametric amplification in a periodically poled MgO:LiNbO 3 waveguide, and detection with a temporally shaped local oscillator.

Use these formats for best results: Smith or J Smith.For best results, use the separate Authors field to search for author names.Use quotation marks " " around specific phrases where you want the entire phrase only.Question mark (?) - Example: "gr?y" retrieves documents containing "grey" or "gray".Asterisk ( * ) - Example: "elect*" retrieves documents containing "electron," "electronic," and "electricity".Improve efficiency in your search by using wildcards.Example: (photons AND downconversion) - pump.

Example: (diode OR solid-state) AND laser.

Note the Boolean sign must be in upper-case.
