  • Publication number: 20020145784
    Abstract: An optical wavelength switching system utilizes wavelength selective splitters and combiners arranged in one or more stages to select one or more wavelengths for optical switching. In an embodiment, the splitters and the combiners comprise tunable optical filters which are capable of being tuned to selected wavelengths for optical switching in a dense wavelength division multiplexing (DWDM) network.

  • Patent number: 5838439
    Abstract: This patent describes a new method for remotely measuring vibration of an object based on laser Doppler vibrometry. The method combines an external two-pass frequency shifting technique with self-mixed, heterodyne detection to provide a compact measurement system that requires only three optical components. A standard diode laser package, consisting of a laser and a monitor photodiode, is used to emit light and detect the scattered signal, a lens is used to collimate the light, and an external modulator is used to shift the optical frequency. The diode laser may be used with or without temperature stabilization. The unique design permits the measurement of objects from a range of long distances without the need for focusing or alignment. Measurements made with the system are characterized by high signal-to-noise ratio, wide dynamic range, and simple alignment.

  • Patent number: 5287421
    Abstract: All-optical modulation occurs in crystalline organic semiconductor waveguides (10a) grown by the ultrahigh vacuum process of organic molecular-beam deposition onto substrates (10b). Two light beams with wavelengths of 1.06 and 0.514 .mu.m from a first source (12) and a second source (34), respectively, may be used as the guided and the pump light sources, respectively. A resonant non-linear coefficient at room temperature of 5.4.times.10.sup.-5 cm.sup.2 /W at 1.06 .mu.occurs at a pump intensity of 1.0 W/cm.sup.2. This large non-linear effect is attributed to free electron-hole pairs produced by the dissociation of excitons generated by the short wavelength beam. A carrier lifetime of (17.+-.1) us, which determines the modulator switching time, is in good agreement with theoretical predictions. This appears to be the first observation of free-carrier-induced index modulation in crystalline organic waveguides.
