➀ Foxconn's research institute and the team from National Yang Ming Chiao Tung University have developed a high-frequency, high-efficiency laser driver circuit based on gallium nitride transistor complementary architecture. ➁ The research team has applied for patents related to the complementary pulse laser driver method using gallium nitride transistors. ➂ The developed high-frequency short-pulse laser driver features a switching frequency of up to 50MHz, pulse width less than 10 nanoseconds, and peak power of 50W, with a conversion efficiency of 75%.
