Manufacturing method of wavelength division multiplexing and demultiplexing device with switching regulation function

Abstract

The invention discloses a manufacturing method of a wavelength division multiplexing and demultiplexing device with the switching regulation function, and belongs to the field of wavelength division multiplexing technologies. According to the manufacturing method of the wavelength division multiplexing and demultiplexing device with the switching regulation function, the number of component structures is small, the loss is small, uniform multiplexing and demultiplexing of the wavelength of multiple signal lights can be achieved, and all branch signal lights on a filtering waveguide light path can be regulated. A reflecting waveguide light path, the filtering waveguide light path and an incoming waveguide light path are manufactured on a core layer according to the semiconductor technology, filtering notches are formed in reflecting points of the reflecting waveguide light path, a light filter which can filter out a branch signal light irradiated on the light filter is installed in each filtering notch, the branch signal lights filtered out by the light filters can continue to be transmitted in the filtering waveguide light path, and the branch signal lights reflected by the light filters can continue to be transmitted in the reflecting waveguide light path.

Description

technical field [0001] The invention relates to the technical field of wavelength division multiplexing, in particular to a manufacturing method of a wavelength division multiplexing and demultiplexing device with switch adjustment function. Background technique [0002] With the rapid development of data services, the speed of network integration is accelerating, and the metropolitan area network is becoming a hot topic in current network construction, and the pressure of market competition makes telecom operators more sensitive to network costs (including construction costs and operation and maintenance costs) . In response to this demand in the market, WDM (Wavelength Division Multiplexing) products for metropolitan area networks emerged as the times require. [0003] WDM can effectively save fiber resources and networking costs. It solves the two problems of fiber shortage and multi-service transparent transmission. It is mainly used in the convergence and access layers...
