Problems solved by technology

Regarding the three-wavelength Triplexer, there is currently a commercially available three-dimensional compact packaging form of discrete devices. This solution consists of multiple discrete components such as focusing lenses, TFF filters, lasers, and detectors. It requires a lot of manual assembly time, and discrete devices are packaged separately. The cost is high; another method is to integrate TFF, PD and LD through flip-chip technology based on the PLC platform. , the assembly process is more difficult

Abstract

The invention provides a hybrid integrated single-fiber three-direction device which comprises a substrate (100), a coarse wavelength division multiplexing array wave-guide optical grate (11), a first input wave guide (10), a first output wave guide (12), a second output wave guide (14), a second input wave guide (13), a laser (15), a first monitoring surface detector (16) and a second monitoring surface detector (17). The hybrid integrated single-fiber three-direction device simplifies the manufacture process, saves the cost, and can be used in low-cost EPON or GPON optical networks.

Description

technical field [0001] The invention relates to a fiber-to-the-home user end optical transceiver, which is a hybrid integrated single-fiber three-way device. The invention can be applied to optical fiber access network. Background technique [0002] Fiber-to-the-home (FTTH) is currently internationally recognized as the most ideal solution for "last mile" high-speed, broadband-to-the-home. It is a hot research and development project with the most development potential and market prospects in the field of optical communications at home and abroad. [0003] At present, FTTH technical solutions based on Ethernet Passive Optical Network (EPON) and Gigabit Passive Optical Network (GPON) are recognized by most experts. Regarding EPON and GPON technical specifications, IEEE802.3ah and ITU-T G984.2 adopt three wavelength distribution schemes of 1310nm, 1490nm and 1550nm. Among them, 1490nm is used for voice, data and IP video signal downlink; 1550nm is used for analog video signa...
