    • An optical frequency division multiplex system including a transmitter, a receiver, and a transmission path connecting the transmitter to the receiver. In the transmitter a master laser is operated to produce a central peak at an optical frequency f.sub.o with side peaks separated by an amount .DELTA.f running to both sides of the central peak. The master laser output goes through an optical isolator to an optical coupler where it is split up into N+1 beams. Each optical output from the coupler is then positioned to be coupled into N slave lasers. Each slave laser is tuned to approximately coincide with one of the side peaks thus producing a single output frequency of (f.sub.o .+-.n.DELTA.f) from each slave laser diode. Electrical modulating signals for each of N information channels are applied separately to modulate the phase of each of the slave laser outputs. The outputs of the slave lasers are then recombined in a N.times.1 optical coupler, the output of which is transmitted over a single-mode fiber linking the transmitter to the receiver. One of the outputs of the 1.times.(N+1) coupler is transmitted to the receiver over a second single-mode fiber. At the receiver, the master laser carrier is split into N spatial components by a 1.times.N coupler. These are then filtered and amplified by a second group of N slave lasers. The output from this second unmodulated group of slave lasers is combined with the combined outputs from the modulated slave lasers in an array of 2.times.1 optical couplers. Finally, the light signals emerging from the couplers are converted to electrical signals for the N information channels by an array of photodetectors.
    • 一种光分频多路复用系统,包括发射机,接收机和将发射机连接到接收机的传输路径。 在发射机中,主激光器被操作以在光频率fo处产生中心峰值,侧峰值与中心峰值两侧运行的量DELTA f分开。 主激光输出通过光隔离器到光耦合器,在那里它被分成N + 1个光束。 然后将来自耦合器的每个光输出定位成耦合到N个从属激光器。 每个从属激光器被调谐到与一个峰值大致重合,从而产生来自每个从属激光二极管的(fo +/- n DELTA f)的单个输出频率。 分别施加N个信息通道中的每一个的电调制信号,以调制每个从激光输出的相位。 从激光器的输出然后在Nx1光耦合器中重新组合,其输出通过将发射器连接到接收器的单模光纤传输。 1x(N + 1)耦合器的输出之一通过第二单模光纤传输到接收器。 在接收机处,主激光器载体被1xN耦合器分成N个空间分量。 然后将它们过滤并由第二组N个从属激光器放大。 来自该第二未调制组的从属激光器的输出与来自调制的从属激光器的组合输出与2x1光耦合器阵列组合。 最后,从耦合器出现的光信号通过一组光电检测器转换成N个信息通道的电信号。

    • 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.
    • 由皮秒光脉冲触发的转移电子装置(TED)微波脉冲和单脉冲发生器。 脉冲发生器包括具有阴极,阳极和位于其间的栅极的TED,全部位于半导体衬底上。 施加到栅电极和阳电极之间的衬底的光脉冲使得多个空间电荷域从栅极顺序地行进到被照射区域,从而导致在TED的外部引线中发生振荡的电流脉冲串。 突发的频率与栅极和照射区域之间的距离成比例,并且突发持续时间与光脉冲幅度和/或持续时间成比例。 或者,突发发生器可以由阴极被处理为栅极的两端TED形成。 可以通过在三端子TED的阴极和栅极之间的衬底上施加光脉冲来形成单个脉冲发生器。 单个脉冲的持续时间与栅极和阳极之间的距离成比例。

    • An optical fiber coil rotation rate sensor including provision for equal intensity dual inputs to its fiber coil to allow the device to operate at the quadrature point and circuitry to continuously adjust the phase in order to maintain operation at that quadrature point regardless of the rotation rate. The system includes an optical fiber coil for counterpropagating light beams therethrough and an input circuit for providing a first and second equal intensity light beams for counterpropagation through the fiber coil. The input circuit comprises a laser light source, a beamsplitter for splitting light from the laser source into two equal intensity beams, first and second elongate fiber waveguides for directing the equal intensity beams to the fiber coil for counterpropagation and including two elongate coextensive close-proximity sections for light beam coupling between the fiber waveguides, and a phase shifter circuit for automatically nulling the phase-shift in the beams returning from the coil. The phase-shift required to null the returning beams is proportional to the fiber coil rotation rate.
