In this ideal mixer, the local oscillator signal is not a sine wave, but an ideal square wave with normal and inverted polarity providing the "push-pull" or balanced LO control to the switches. However, practical circuits do not have zero loss resis-tance or instantaneous transition times, so an analysis of

In such a mixer, you'll see harmonically related output similar to that you'd obtain with square-wave local oscillator input. So it is unwise to assume that a sine wave input to local-oscillator guarantees fewer harmonics at mixer output. The local oscillator port of a saturated-switch type mixer described above should be assumed non-linear.

A novel heterodyne detection technique is introduced for femtosecond time resolved four wave mixing (TRFWM). A 'local oscillator' field is generated in situ either by the self alignment of the molecules in the ultrashort field, or by the rotational alignment signal from a small amount of anisotropic molecules added to the sample.

We demonstrate, for the first time to our knowledge, optical parametric oscillation based on four-wave mixing in microstructure fiber. The measured wavelength-tunability range of the device (40 nm) and the threshold-pump peak power (34.4 W) are in good agreement with the theory of four-wave mixing in optical fibers. The ellipticity of the fiber's polarization modes allows the device …

There are several ways for generating squeezing: using (i) parametric down conversion (three-wave or four-wave mixing), (ii) photon emissions by transions between pairs of different energy levels of the atom, or (iii) optical fibres (three-wave mixing), etc. Non-linearity (that is, non-linear dependence of polarization of light inside the ...
