Abstract: Disclosed is a servo matching control mid-infrared differential dual-wavelength laser based on Nd:MgO:PPLN, The 813 nm semiconductor pumping source, the energy transmitting optical fiber, the first focusing lens, the second focusing lens, the first 45-degree beam splitter, the mid-infrared idle frequency light output mirror, the polarized crystal, the servo motor, the mid-infrared parametric light total reflection mirror, the microprogrammed control unit, the second 45-degree beam splitter, the electro-optical crystal and the 1093 nm fundamental frequency light total reflection mirror are sequentially placed from right to left in a straight cavity of the laser; and the 1084 nm fundamental frequency light total reflection mirror is placed in a bent-shape cavity of the laser, corresponding to a position of the second 45-degree beam splitter, such the second 45-degree beam splitter can reflect incident light to the 1084 nm fundamental frequency light total reflection mirror.

Abstract: A method, system, and apparatus of a balanced rotator conversion of serialized data are disclosed. In one embodiment, a method to convert serialized data includes acquiring a rotator module output, and generating a balancing signal with a reference module, which operates with a reference frequency. The method further includes processing the rotator module output and the balancing signal in an interpolation module to generate a balanced rotator output. The method may include a rotator module output that is generated by an analog phase rotator when a control voltage is received by the analog phase rotator. The reference module may include an other analog phase rotator to generate a balancing signal. The interpolation module may interpolate the balancing signal and the rotator module output to modulate a phase of the balanced rotator output. The balanced rotator output may include an orthogonal output.
