摘要	To provide an optical waveguide and an optical transmitting and receiving module able to perform a transmitting operation and a receiving operation simultaneously, wherein a linearly first waveguide 21 that one side is coupled to an optical fiber 3 and the other side is coupled to a light receiving element 4, and a second waveguide 22 that one side is coupled so as to make an acute angle θ with the side of the first waveguide 21 to be coupled to the light receiving element 4 and the other is coupled to a light emitting element 5 are provided. By controlling a shape of the second waveguide 22, the receiving signal light from the optical fiber 3 is received to the light receiving element 4, and is not guided to the second waveguide 22. Therefore, the receiving operation and the transmitting operation can be preformed at the same time. Namely, when the transmitting optical signal is the incident of light from the light emitting element 5 to the second waveguide 22, the optical signal is guided by the second waveguide 22 toward the first waveguide 21, coupled to the first waveguide 21, and guided toward the optical fiber 3.
其他摘要	提供一种能够同时执行发送操作和接收操作的光波导和光发送和接收模块，其中一侧耦合到光纤3并且另一侧耦合到光接收的线性第一波导21元件4和第二波导22，其一侧耦合以便与第一波导21的一侧形成锐角θ以耦合到光接收元件4而另一侧耦合到发光元件5。提供。通过控制第二波导22的形状，来自光纤3的接收信号光被接收到光接收元件4，并且不被引导到第二波导22.因此，可以执行接收操作和发送操作。同时。即，当发射光信号是光从发光元件5入射到第二波导22时，光信号被第二波导22引导向第一波导21，耦合到第一波导21，并被引导向第一波导21。光纤3。
主权项	An optical waveguide comprising: a first waveguide having a common transmitting and receiving port at one side and a receiving port at the other side, extending linearly, and able to guide an optical signal in bi-direction, and a second waveguide branching off from said first waveguide so as to make an acute angle with said receiving port, coupling said first waveguide at one side, having a transmitting port at the other side, and guiding an optical signal to said first waveguide.
