摘要： A surface-plasmon-polaritons (SPPs) tunable optical resonant ring filter that includes an SPPs waveguide, an SPPs tunable directional coupler, and an SPPs tunable resonant ring. The tunabilities of the resonant frequency, the resonant depth, and the filtering bandwidth are achieved by tuning the loss and transmission phase of the resonant ring and the coupling ratio of the directional coupler. Since the metal core layer of the SPPs waveguide is capable of multiplexing electro-optical signals, the SPPs tunable optical resonant ring filter can be used not only in an integrated optics system, but also in an integrated electro-optics hybrid system.

摘要： A power converter that is operable to convert AC power into DC power that may be delivered to a load. The power converter operates to bypass a power factor correction (PFC) circuit during a portion of each AC power cycle. The power converter bypasses the PFC circuit when an AC input voltage is greater than a DC output voltage. The power converter may also include sensing circuitry to sense the AC input voltage and the DC output voltage of the power converter. The power converter may include one or more diodes that function to deliver power directly to a load when the AC input voltage is greater than the DC output voltage, thereby bypassing the PFC circuit. The DC output voltage of the power converter may be regulated to a level that is less than the peak AC input voltage.
