Abstract

The invention discloses an array waveguide grating module with polarization control. An input waveguide is connected with an input end of a polarization beam splitting-rotator, two output ends of the input waveguide and the polarization beam splitting-rotator are respectively connected with respective a first slab waveguide and a second slab waveguide through a first connecting waveguide and a second connecting waveguide, a group of array waveguides are connected between the first slab waveguide and the second slab waveguide, one end of each output waveguide of a first output waveguide group is an output port, the other end of each output waveguide of the first output waveguide group is connected with the first slab waveguide and is positioned on the same side of the first connecting waveguide, one end of each output waveguide of a second output waveguide group is an output port, and the other end of each output waveguide of the second output waveguide group is connected with the second slab waveguide and is positioned on the same side of the second connecting waveguide. Only the standard process of array waveguide grating manufacturing is needed, the array waveguide grating module with the polarization control can be used as a polarization insensitive receiving module in a wavelength division multiplexing system, or as a receiving and transmitting module in a wavelength division multiplexing-polarization multiplexing mixing multiplexing system.

Description

technical field [0001] The invention relates to a planar optical waveguide integrated device, in particular to an arrayed waveguide grating module with polarization control. Background technique [0002] As we all know, light as a carrier has achieved great success in long-distance communication, and is advancing to the field of short-distance optical communication, such as fiber-to-the-home (FTTH), optical interconnection and other systems. In these optical communication systems, in order to obtain greater data transmission capacity, people have developed a variety of multiplexing technologies, including wavelength division multiplexing, polarization multiplexing, time division multiplexing, and so on. [0003] Among them, wavelength division multiplexing (WDM) technology has achieved great success in long-distance optical fiber communication, and its core device is a wavelength division multiplexing-demultiplexing device, and the most representative one is the arrayed wave...
