Title:
ARRAYED WAVEGUIDE GRATING MODULE HAVING WIDE TEMPERATURE RANGE AND LOW POWER CONSUMPTION AND WAVELENGTH CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/041680
Kind Code:
A1
Abstract:
Provided are a grating module and a wavelength control method. The grating module comprises: a temperature compensation device (1) comprising an optical path base consisting of a plurality of independent sub-regions and a drive rod (103) connected to the respective sub-regions of the optical path base; and an AWG chip assembly (2) divided into multiple sub-regions, each sub-region being provided at one of the sub-regions of the optical path base, wherein the optical path base is provided with a module temperature control device (5). In the invention, the module temperature control device (5) is used to control a temperature of the grating module, and the actual operating temperature range is divided into two or multiple sections, thereby reducing energy consumption, and more precisely controlling a compensation amount with respect to a wavelength of an optical module.
