光收发装置、光线路终端、光网络单元及无源光网络系统
摘要：
一种光收发装置，包括若干光发射机、若干光接收机及波导芯片，所述光接收机通过所述波导芯片接收来自光网络传输的第二光束，所述波导芯片包括第一包层、第二包层以及设置于所述第一包层及所述第二包层之间的芯层，所述光接收机设置于所述第一包层上，且所述波导芯片靠近所述光接收机的端面设置成具有预定角度的斜面，所述第二光束传输至所述芯层，并在所述芯层中传输到达所述斜面，所述第二光束在所述斜面上发生反射后传输至所述第一包层的表面，并被位于所述第一包层上的所述光接收机接收。本发明的光收发装置，具备抗串扰能力高、制作工艺简单，制造成本低等优点。
摘要（英）：

A light transmitting-receiving device comprises multiple light emitters, multiple light receivers and a waveguide chip, wherein the light receivers receive a second light beam, transmitted by an optical network, via the waveguide chip, the waveguide chip comprises a first cladding, a second cladding and a core layer arranged between the first cladding and the second cladding, the light receivers are arranged on the first cladding, and the end surface, close to the light receivers, of the waveguide chip is provided with an inclined plane of preset angle. The second light beam is transmitted to the core layer, transmitted in the core layer, reaches the inclined plane, reflected at the inclined plane, transmitted to the surface of the first cladding, and received by the light receivers positioned on the first cladding. The light transmitting-receiving device has the advantages including high crosstalk resistance, simple manufacture technology and low manufacture cost.
