  • Pulse measurement using frequency shifting techniques
    Patent number: 6611336
    Abstract: Amplitude and phase relative to an interferometrically established phase of ultrashort replica pulses (15) utilizes spectral phase interforemetry for direct electric field reconstruction by frequency shifting chirp replica pulses (16) of an optical pulse to be measured. The replicas of the pulses, relatively delayed in time, are generated by an interferometer (12).

  • Fabry-Perot optical switch
    Patent number: 6490381
    Abstract: The absorption of a spacer material in a Fabry-Perot type structure is changed to achieve an optical switching function. In one embodiment, the spacer material is a semiconductor material and an electronic control signal changes the Fabry-Perot between a transmissive state and a reflective state. In the reflective state, the device operates as a switch can be modeled as a mirror on a substrate of quasi-infinite thickness. In a further embodiment, a wavelength-selective optical component is placed between the input of the switch and the Fabry-Perot structure to improve the spectral response of the switch.
