Abstract

The invention relates to a package structure of a variable optical attenuator multiplexer. The package structure of the variable optical attenuator multiplexer comprises a package box composed of an upper cover and a lower bottom, wherein a control circuit board is fixed to the lower bottom, a silicon waveguide mode array variable optical attenuator and an array waveguide optical grating are fixed to the control circuit board, and a fiber channel of the silicon waveguide mode array variable optical attenuator and a fiber channel of the array waveguide optical grating are correspondingly connected through fibers. Meanwhile, the invention relates to a manufacturing method of the package structure. The silicon waveguide mode array variable optical attenuator based on the photoelectric absorption effect is adopted to manufacture the variable optical attenuator multiplexer, the reliability is good, the response speed is high, the response time reaches the microsecond level, heating is not required, and power consumption is lower.

Description

technical field

[0001] The invention relates to an optical power adjustable combiner in the field of optical fiber technology, in particular to a packaging structure and a preparation method for manufacturing an optical power adjustable combiner based on a silicon waveguide array adjustable optical attenuator. Background technique

[0002] With the development of optical fiber communication towards high speed and large capacity, the combination of Erbium-Doped Fiber Amplifier (EDFA) and Dense Wavelength Division Multiplexing (DWDM) technology has become the The main technical means in. The optical power tunable multiplexer (referred to as "VMUX") is the core device in the DWDM system and has broad market prospects. It can solve the gain unevenness caused by the use of optical fiber amplifiers and the power jump caused by the increase or decrease of channels. , by dynamically adjusting the optical power of each channel of the system to achieve balance, so as to realize the l...
