摘要： Transferred-electron device (TED) microwave burst and single pulse generators which are triggered by picosecond optical pulses. The burst generator includes a TED having a cathode, an anode, and a gate electrode positioned therebetween, all located on a semiconductor substrate. An optical pulse applied to the substrate between the gate and anode electrodes causes a plurality of space charge domains to sequentially travel from the gate to the illuminated region thereby causing an oscillatory burst of current to occur in the external leads of the TED. The frequency of the burst is proportional to the distance between the gate and the illuminated region and the burst duration is proportional to the optical pulse amplitude and/or duration. Alternatively, the burst generators may be formed from a two terminal TED with the cathode electrode being treated as the gate. A single pulse generator may be formed by applying an optical pulse to the substrate between the cathode and the gate of a three terminal TED. The duration of the single pulse is proportional to the distance between the gate and the anode.

摘要： A pulsed laser includes a polarization section having a port, the polarization section being for receiving light at the port in a selected state of polarization and for outputting light at the port having a state of polarization orthogonal to the selected state of polarization. The laser also includes an amplifying section having a port, a bidirectional amplifier, and a rotator-reflector, the amplifying section being for receiving light at the amplifying section port and for outputting light at the amplifying section port amplified with respect thereto, the bidirectional amplifier being operatively coupled to the amplifying section port at a first end and operatively coupled to the rotator-reflector at a second end. The pulsed laser further includes means for transmitting light in both directions between the polarization section port and the amplifying section port, an amplitude modulator responsive to a modulation signal for actively mode-locking light internal to the pulsed laser, and means responsive to light internal to the polarization section for outputting coherent light.

摘要： A semiconductor photodetector employs a multilayer structure for controlling speed, efficiency and noise. A light-absorbing low band gap semiconductor emitter layer produces photogenerated charge upon absorption of light. A semiconductor collector layer collects the photogenerated charge. A semiconductor barrier layer between the light absorbing layer and the collector layer selectively blocks substantially all but photogenerated charge. A base layer may be optionally employed between the barrier layer and the collector layer for gating the current flow and controlling wavelength sensitivity.

摘要： The ultrashort fiber laser with a dispersion-managed cavity. The laser is an actively mode-locked sigma laser, typically locked at a repetition rate of 10 GHz, driven by an external frequency source and actively length stabilized, and nearly 10,000 pulses circulate within the laser cavity. A Mach-Zehnder modulator is placed in a loop of polarization-maintaining (PM) fiber. The polarization state of light injected into the non-PM branch evolves in a random manner but is transformed into an orthogonal state by a Faraday mirror; linearly polarized light injected into the branch by a polarizing beamsplitter returns to the beamsplitter also linearly polarized but rotated by 90°. The cavity of the laser is composed of several fibers. The average dispersion Dav is anomalous and is approximately equal to 0.1 ps/(nm·km).
