The independent temperature control components (3) and the active chips (4) are in one-to-one correspondence, the high-speed device controls the active chips (4) to emit light, the light emitted by the active chips (4) is output through the wavelength division multiplexing unit (5), and the independent temperature control components (3) are used for adjusting the temperature of the active chips (4). The high-speed device can precisely control the work temperature and work wavelength of each active chip, the light beam output quality of the high-speed device is greatly improved, the technical scheme including a core function unit can be selectively adopted, or the technical scheme that different extended functions are added on the basis of the core function unit is adopted, and high flexibility is achieved.

Description

technical field [0001] The invention belongs to the fields of communication and optoelectronics, and relates to a high-speed device based on accurate spectral matching technology and a manufacturing method thereof, especially for high-precision matching of the wavelength of a high-speed laser chip and the passband range of a wavelength division multiplexing element. Background technique [0002] As the communication industry's demand for bandwidth continues to increase, the bandwidth requirements of lasers and optoelectronic devices used in the communication industry are also getting higher and higher. Because the modulation rate of a single active chip in the existing technology is not enough to support the bandwidth requirements, various multiplexing technologies have been used, such as wavelength division multiplexing technology to solve the insufficient modulation rate of a single active chip and the wide bandwidth. limited problem. In the wavelength division multiplexi...

Problems solved by technology

However, the wavelength center of each channel of the wavelength division multiplexing element is approximately matched with the center wavelength design of the chip, but the actual production result is not really matched, which further leads to the fact that the multi-channel die and the wavelength division multiplexing element are assembled on the same When in the device, the output light of each wavelength is different, and it is even possible that some wavelengths have almost no light output
