However, in a cavity-based system the squeezing bandwidth is limited by the cavity bandwidth. In their experiment, optical cavities were employed to enhance the optical nonlinearity, and to reduce the phase noise and spatial-mode mismatching with a local oscillator (LO). Observation of 10 dB squeezing was recently reported by Vahlbruch et al., showing that strong squeezing as required for practical applications is possible. In particular, broadband squeezed light at telecommunication wavelength would be the powerful resource for practical implementations of CVQC, because optical transmission loss in a glass optical fiber is minimum at the telecommunication band, and the broadband source is required for the high-speed and broadband communications. Quadrature-squeezed light is an important resource for continuous-variable quantum communication (CVQC) technology, such as quantum teleportation and dense coding. 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. Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored.Use a comma to separate multiple people: J Smith, RL Jones, Macarthur.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.

Note the Boolean sign must be in upper-case.

Separate search groups with parentheses and Booleans.

Keep it simple - don't use too many different parameters.
