Array waveguide grating with channel monitoring function

Abstract

The invention provides an array waveguide grating with a channel monitoring function. The array waveguide grating comprises an AWG and a PLC type split light coupler which are integrated on a same waveguide substrate, and the PLC type split light coupler is arranged on a channel, needing to be monitored, of an input waveguide or output waveguide of the AWG. According to the device, an additional chip manufacturing process is not added, special design on the AWG is not needed, the process is simple, and the large-scale production requirements are met; integration of the split light coupler with a monitoring function and the AWG single chip is achieved, and the structure is compact.

Description

technical field [0001] The invention relates to an arrayed waveguide grating with channel monitoring function, which belongs to the communication field. Background technique [0002] With the completion of 40 / 100 Gigabit Ethernet (GbE) optical interface standard (IEEE802.3ba-2010) and pluggable optical transceiver module standard (CFP-MAS Rev 1.4), and the first generation of 40GbE / 100GbE CFP products Gradually entering the market, manufacturers are gradually shifting their attention to the R&D and design of 40 / 100GbE pluggable transceivers. For system manufacturers and customers, module power consumption and size are the key indicators to increase system port density and reduce the cost of the entire optical port, so it has become the primary goal of R&D and design, and the monolithic integrated waveguide solution is the mainstream implementation solution. [0003] IEEE 802.3ba-2010 defines the most widely used 40GBase-LR4 optical interface working at 1310nm, 4-wavelength ...

AI Technical Summary

Problems solved by technology

The scheme of thinning the waveguide cladding requires an additional process of photolithography and overlay; the scheme of using the second AWG makes the chip too large and complicated; the scheme of using different diffraction orders and output waveguide coupling and splitting needs to AWG for special design

The realization of these technical solutions is too complicated, which is not conducive to productization
