    • Two-terminal multi junction photodetectors and focal plane arrays for multi-color detection or imaging acquisition can be formed by connecting photodiodes with different bandgaps or wavelengths, through tunnel diodes, in series with the same polarization. Under reverse bias in the dark, the total current going through such multi junction photodetectors is dictated by the smallest reverse saturation current of the photodiodes. When in operating mode, a set of light sources with different wavelengths corresponding to each individual photodiode can be used to optically bias all the photodiodes except the detecting photodiode Under illumination, all other photodiodes work in the photovoltaic mode and have much higher maximum possible reverse currents than the detecting photodiode. As a result, the total current of the multi junction photodetector is dictated by the detecting photodiode. Therefore, a total current can be read by, for example, read-out circuits to give the optical signal strength at that specific wavelength of the detecting photodiode. By using an algorithm one can use such multi junction photodetectors to detect different wavelengths and to take multicolor images.
    • 可以通过连接具有不同带隙或波长的光电二极管,通过隧道二极管与相同的极化串联,形成用于多色检测或成像采集的两端多结光电探测器和焦平面阵列。 在黑暗中的反向偏置下,通过这种多结光电探测器的总电流由光电二极管的最小反向饱和电流决定。 当处于工作模式时,可以使用一组与各个光电二极管相对应的具有不同波长的光源来光学偏置检测光电二极管外的所有光电二极管。在照明下,所有其他光电二极管工作在光伏模式,并具有高得多的最大可能反向电流 比检测光电二极管。 结果,多结光电检测器的总电流由检测光电二极管决定。 因此,可以通过例如读出电路来读取总电流,以在检测光电二极管的特定波长处给出光信号强度。 通过使用算法,可以使用这种多结光电探测器来检测不同波长并采取多色图像。

    • An electron emitter provides a photocell having at least one photosensitive side, an electron accelerator, an electron collector disposed between the photosensitive side of the photocell and the electron accelerator, a non-metallic vacuum chamber having an adjustable vacuum containing the photocell, the electron accelerator and the electron collector; and a light source to excite electrons on the photosensitive side of the photocell. Upon light activation, infrared light strikes the photocell, causing electrons to be excited and released. The highly positively charged electron accelerator will attract the electrons under sufficient vacuum conditions. Some of the electrons travelling towards the electron accelerator will encounter the electron collector and be collected thereon. The device may be used as a rectifier or regulator to replace vacuum tubes such as for audio amplifiers and high voltage devices. It may also have application as an x-ray generator, an electron microscope or a display screen.

    • An electron beam pumped laser including a surface-emitting laser faceplate oriented at a non-perpendicular angle. Embodiments are described in which a bending coil bends the electron beam, or in which the faceplate is situated in the direct path of the e-beam emission but with a non-zero orientation angle. The faceplate may include a substantially opaque substrate, and an opaque heat-removing structure may be attached to the substrate to provide high heat transfer, thereby allowing high electron-beam pumping intensity and providing more light emission from a smaller package. In some embodiments the partially reflective mirror comprises a metal layer that has a plurality of openings. Multiple laser faceplates (e.g., red, green, and blue) may be placed in the same tube, to provide a continuous light source for projection television. The substrate may be connected to ground to provide an exit path for electrons from the laser gain layer.
