Multi-junction VCSEL Technology

Eaglescomesi has developed a multi-junction VCSEL technology for the international semiconductor industry. It has lower current, higher efficiency and faster speed. As a new round of development of VCSEL, multi-junction technology can be applied to the Company's product portfolio.

Advantages of which mainly lie in:

Higher efficiency that can reduce the overall heat load;

Higher power density that can greatly reduce the chip and package size, thus simplifying the optical design and system architecture;

Higher slope efficiency means that the same optical power as single-junction VCSEL can be achieved with very low forward pulse current, advantage of which is that the required current is greatly reduced, thus the switching speed of the driver is improved. The reduction of current enables VCSEL to emit 1ns pulse of tens or even hundreds of watts.

Eaglecomsemi's multi-junction VCSEL technology has the following strengths: taking into account design and reliability, and achieving faster speed through optimized design, our multi-junction VCSEL technology has not sacrificed reliability but contributed to meet the need of more stringent scenes such as vehicle-specification level, high efficiency and high power density;

With high portability, can be combined with flip-chip VCSEL technology and multi-partition addressable VCSEL technology to produce Butterfly Effect. It can be said that multi-junction VCSEL technology has become the cornerstone of new technologies in the future.
