Broad applications in aerospace communications
Broadband communication network based on LEO satellite constellation has become the main form of next-generation communication technology, and inter-satellite laser communication is one of the core technologies of constellation networking. Inter-satellite laser communication system refers to the optical communication system using laser light wave as carrier wave. Inter-satellite laser communication combines the advantages of fiber optic communication and microwave communication, which has the advantages of both large communication capacity and high speed transmission, and becomes the preferred solution for inter-satellite network. But because of the small temperature fluctuations can lead to laser chip wavelength drift, and affect the signal output power and communication signal stability, and no fiber shielding against external interference, the loss of optical signal protection, which has higher requirements for the light source, in addition to the requirements of good output beam quality, high operating frequency, narrow beam, but also consider the laser output power stability, frequency stability, beam direction Stability and working life, etc.
For optical components in laser emitters
Temperature is precisely controlled
The latest MicroTEC specification developed by Hong Chang Electronics adopts the eutectic point of 280℃ (556℉) gold-tin welding process, and the internal welding layer has excellent properties such as high thermal conductivity, high welding strength, fatigue resistance, creep resistance, etc. In addition, in terms of core basic thermoelectric semiconductor materials, Hong Chang Electronics has produced fine crystal reinforced thermoelectric crystal blocks through SPS alloying process, which effectively solves the problems of poor thermal and mechanical properties of domestic materials. This, coupled with the automated production line with process control and metrology inspection functions, ensures high process accuracy, high batch consistency and good product reliability in mass production, enabling it to fully meet the requirements for Micro TEC temperature control performance and reliability in aerospace, medical and other fields.
TEC is focused on making up for the shortcomings of the 5G optoelectronic device "China Core" by making up for the "substrate material", "chip manufacturing" and "packaging test" in the chip industry chain. "It is a leading supplier of substrate materials, chip manufacturing, and packaging and testing. Performance indicators in the domestic leading level, mainly used in 5G communication core equipment optical modules. Solve the problem of shortening the service life of optical module, occurring red shift, wavelength lengthening, optical output power reduction, and even no signal due to temperature increase. How to accurately control the temperature of the optical chip is the key to ensure normal communication, and TEC temperature control can reach 0.01℃.
