摘要	A modulation technique for optical signals. A laser diode having an outcoupling grating in the waveguide between two reflectors is provided. A second waveguide is positioned next to the first waveguide. The first end of the second waveguide is optically connected to the first waveguide on one side of the outcoupling grating, while the second end of the second waveguide is optically connected to the first waveguide on the other side of the outcoupling grating. Switches are provided that control the amount of light coupled between the waveguides. For example, when the switches are in a first state, no light is coupled between the two waveguides, and all the light stays in the laser diode or is coupled out of the outcoupling grating, while none of the light couples into the second grating; and when the switches are in a second state, some or all of the light from the first waveguide is coupled into the second waveguide. By toggling the states of the switches, the light emitted from the laser diode is modulated.
其他摘要	一种光信号调制技术。提供了在两个反射器之间的波导中具有向外耦合光栅的激光二极管。第二波导紧邻第一波导定位。第二波导的第一端光学连接到输出耦合光栅一侧的第一波导，而第二波导的第二端光学连接到输出耦合光栅另一侧的第一波导。提供开关以控制波导之间耦合的光量。例如，当开关处于第一状态时，在两个波导之间没有光耦合，并且所有光都停留在激光二极管中或耦合出耦合输出光栅，而没有光耦合到第二光栅中;当开关处于第二状态时，来自第一波导的一些或全部光耦合到第二波导中。通过切换开关的状态，调制从激光二极管发射的光。
