    • There is provided an assembly of a light source and an optical detector, each using a vertical cavity surface emitting laser (VCSEL). To control light emission of the VCSEL light source, spontaneous light emitted laterally therefrom is converted into an electrical signal. The optical detector for monitoring light is provided around the light source to supply the feedback electrical signal. The inner surface facing the light source of the optical detector is circular to absorb the spontaneous light and the outer surface thereof is polygonal having a plurality of peaks and valleys. Therefore, most of spontaneous light absorbed in the optical detector is reflected within, not penetrating the outer surface thereof, thereby extending the path of the spontaneous light in the optical detector and increasing the light intensity converted into an electrical signal.
    • 提供了一种光源和光学检测器的组件,每个使用垂直腔表面发射激光器(VCSEL)。 为了控制VCSEL光源的发光,将其侧向发射的自发光转换成电信号。 在光源周围设置用于监视光的光检测器,以提供反馈电信号。 面向光学检测器的光源的内表面是圆形的以吸收自发光,并且其外表面是具有多个峰和谷的多边形。 因此,在光检测器中吸收的大部分自发光被反射到内部,不会穿透其外表面,从而延长光学检测器中自发光的路径,并增加转换成电信号的光强度。

    • A silicon optoelectronic device includes an optoelectronic device portion and a switching portion. The switching portion selectively controls the emission and detection of light by the optoelectronic device portion. The optoelectronic device portion includes: a doped region of the opposite type to an n- or p-type silicon-based substrate, in which emission and detection of light occurs due to quantum confinement effect at the p-n junction between the doped region and the substrate, and at least one semiconductor material region formed on the rear surface of the substrate, at least a portion of which forms a stack structure with the doped region so that a built-in transistor is formed. The silicon optoelectronic device allows selective light emission and detection without any external amplifying and switching circuits, easy control the duration of light emission and detection, and can be manufactured in a series of semiconductor fabrication process.
