    • A grating based optical transmitter includes a light source region coupled to an interference region, two reflective regions on both sides of the interference region, and one or several gratings interacting with the interference light wave in the interference region causing a vertical emission. Two electrodes are used to inject electrical carriers, and a third electrode can be added to modulate the electrical carrier density recombined in the light source region. Compared to conventional edge-emitting laser with two electrodes, the grating-based optical transmitter in this invention largely reduces the packaging cost and complexity due to the vertical emission, and largely enhances the modulation bandwidth due to the three-terminal configuration.
    • 基于光栅的光学发射器包括耦合到干涉区域的光源区域,位于干涉区域两侧的两个反射区域以及与干涉区域中的干涉光波相互作用的一个或多个光栅 造成垂直排放。 两个电极用于注入电载流子,并且可以添加第三电极来调制在光源区域中重新组合的电载流子密度。 与具有两个电极的常规边缘发射激光器相比,本发明中基于光栅的光发射器由于垂直发射而大大降低了封装成本和复杂性,并且由于三端配置而大大增强了调制带宽。
