The invention discloses a curve-shaped arrayed waveguide grating (AWG) dense wavelength division multiplexing device with heat and a manufacturing device, manufacturing method and testing method thereof. The structure of the wavelength division multiplexing device is introduced in a detailed mode. The wavelength division multiplexing device comprises a packaging box, glass cover plates and a temperature monitoring component. An AWG chip, a single fiber coupled with the input end of the AWG chip and a monocrystalline silicon fiber array coupled with the output end of the AWG chip are placed in the packaging box. The glass cover plates are arranged at the coupling positions of the input end and the output end of the AWG chip respectively. The coupling area is increased through the glass cover plates. The temperature monitoring component comprises a temperature control device and at least two heating drivers arranged on one side of the single fiber. A whole set of technological process is matched, so that the working bandwidth wavelength coverage of the manufactured wavelength division multiplexing device is 1528 nm-1565 nm, wavelength division is even, performance is stable, and related loss such as polarization loss is low.
Description
technical field [0001] The invention relates to the manufacturing field of optical devices, in particular to a curved thermal AWG arrayed waveguide grating dense wavelength division multiplexer and its manufacturing device, manufacturing method and testing method. Background technique [0002] Due to the large-scale FTTH network deployment, and the traditional broadband in my country mainly adopts the copper broadband technology represented by ADSL, it is difficult to meet the increasing broadband demand of users. Thermal AWG arrayed waveguide grating dense wavelength division multiplexer has the advantages of uniform channel loss, small size, easy integration, and convenient mass production. At the same time, through the continuous upgrading of FTTH core technology PON, thermal AWG arrayed waveguide The user can easily provide 1G, 2.5G or even several 10G bandwidth on the node of the optical access network, and the access rate of each user is correspondingly increased rapid...
