Abstract

Disclosed are a transmitting-receiving optical component and an optical module. The transmitting-receiving optical component comprises a transmitting device, a receiving device and a filter device, wherein the transmitting device and the filter device are integrated into the same chip and the receiving device is fixed on the outer surface of the chip; on one aspect, the transmitting device transmits an optical signal and sends the optical signal to the outside via the filter device; and on the other aspect, the transmitting device receives an optical signal transmitted from the outside and reflects the optical signal into the receiving device via the filter device. The optical module is provided with the transmitting-receiving optical component. According to the present invention, a receiving device is arranged externally on the outer surface of a chip, while a transmitting device is integrated into the chip, so that the possibility that an optical signal may generate crosstalk to the receiving device is reduced greatly, thereby reducing or even eliminating the influence of the receiving device on the receiving performance of other optical signals. Moreover, the present invention is simple in structure, the size of the chip is decreased and the cost is reduced.

Description

Technical field [0001] The invention relates to the field of electronics, in particular to a light-receiving component and an optical module. Background technique [0002] Passive optical network PON (passive optical network) technology has become the most favored solution for operators in the field of optical fiber access FTTx (FiberToTheX) by virtue of its point-to-multipoint network architecture and passive advantages. But the large-scale deployment of PON technology is directly restricted by the cost of active optical components. The commonly used active optical component is a kind of light-receiving component, which mainly includes: transmitting device, receiving device, filter device. On the one hand, the transmitting device emits light signal, and the light signal is transmitted to the outside through the filter device, and on the other hand, it receives the outside world. The transmitted optical signal is reflected by the filter into the receiving device, and the receivi...
