Problems solved by technology

[0003] At present, the technology developed by AWG has been developing toward integration and miniaturization, but AWG series interference forces AWG to adopt stacking technology and cascading technology, and the bending of the Roland ring makes AWG devices bulky and difficult to integrate. Combined, it is bulky and expensive

Abstract

The invention discloses a wavelength divider and a power divider on the basis of stereoscopic straight arrayed waveguide grating. AWG (arrayed waveguide grating) chips which are arranged on bottom plates are different from the traditional crank arm type arrayed waveguide structures and are of sinusoidal crank arm arrayed waveguide structures, and the purpose of acquiring optical path difference can be achieved by means of changing cycle numbers of sinusoidal waves; waveguide coupling structures are further arranged above output FPR (floating point routine) (star couplers), so that purposes of the power divider can be achieved. Integrated devices are different from the traditional AWG structures, can be of straight AWG structures and can have waveguide coupling and power dividing functions, AWG elements can be greatly diminished, processes are easy to implement, and the wavelength divider and the power divider have the advantages of small size, light weight, easiness in integration and the like and are applicable to mass production.

Description

technical field [0001] The invention belongs to the field of integrated photonic devices, and relates to a wavelength / power splitter based on a three-dimensional straight arrayed waveguide grating. Background technique [0002] AWG (Arrayed Waveguide Grating) is the preferred technology in dense wavelength division multiplexing system (DWDM). A grating formed by a group of arrayed waveguides with equal length differences has the ability to split waves. The principle is: After the multiplexed signal light with multiple wavelengths is output through the central input channel waveguide, it is diffracted in the input slab waveguide, reaches the input concave grating for power distribution, and is coupled into the array waveguide area. Since the end face of the array waveguide is located on the circumference of the grating circle, the diffracted light reaches the end face of the array waveguide with the same phase. After being transmitted through the arrayed waveguide, since th...
