    • A charged particle beam including charged particles (e.g., electrons) is generated from a charged particle source (e.g., a cathode or scanning electron beam). As the beam is projected, it passes between plural alternating electric fields. The attraction of the charged particles to their oppositely charged fields accelerates the charged particles, thereby increasing their velocities in the corresponding (positive or negative) direction. The charged particles therefore follow an oscillating trajectory. When the electric fields are selected to produce oscillating trajectories having the same (or nearly the same) frequency as the emitted radiation, the resulting photons can be made to constructively interfere with each other to produce a coherent radiation source.
    • 从带电粒子源(例如阴极或扫描电子束)产生包括带电粒子(例如电子)的带电粒子束。 当光束投射时,它通过多个交变电场。 带电粒子对其带电荷的场的吸引力加速了带电粒子,从而在相应的(正或负)方向上增加了它们的速度。 带电粒子因此遵循振荡轨迹。 当选择电场以产生具有与发射的辐射相同(或几乎相同的)频率的振荡轨迹时,可以使得到的光子相互干涉以产生相干辐射源。

    • When using micro-resonant structures, a resonant structure may be turned on or off (e.g., when a display element is turned on or off in response to a changing image or when a communications switch is turned on or off to send data different data bits). Rather than turning the charged particle beam on and off, the beam may be moved to a position that does not excite the resonant structure, thereby turning off the resonant structure without having to turn off the charged particle beam. In one such embodiment, at least one deflector is placed between a source of charged particles and the resonant structure(s) to be excited. When the resonant structure is to be turned on (i.e., excited), the at least one deflector allows the beam to pass by undeflected. When the resonant structure is to be turned off, the at least one deflector deflects the beam away from the resonant structure by an amount sufficient to prevent the resonant structure from becoming excited.
    • 当使用微谐振结构时,可以打开或关闭谐振结构(例如,当响应于改变的图像打开或关闭显示元件时,或者当通信开关被打开或关闭以发送数据不同的数据位 )。 不是打开和关闭带电粒子束,而是可以将光束移动到不激发谐振结构的位置,从而关闭谐振结构,而不必关闭带电粒子束。 在一个这样的实施例中,至少一个偏转器被放置在带电粒子源和待激发的谐振结构之间。 当谐振结构要被接通(即激励)时,至少一个偏转器允许光束通过未偏转。 当谐振结构要关闭时,至少一个偏转器将光束从谐振结构偏离足以防止谐振结构被激发的量。
