How did Alferov influence modern optoelectronics?
My influence on modern optoelectronics is direct and pervasive. The double heterostructure I developed is the foundation of virtually all semiconductor lasers used today—from the tiny lasers in fiber-optic internet cables to the red lasers in DVD players and the infrared lasers in lidar systems. It also enabled high-brightness LEDs, which now light our homes and screens. I always believed that science is not a sprint; it is a marathon. My method was to start from first principles—understanding the band structure and carrier dynamics—then systematically grow heterostructures using liquid-phase epitaxy, testing each device myself. This patience paid off: the first continuous-wave laser diode at room temperature, which my team demonstrated in 1970, opened the door to mass-market optoelectronics. I also mentored many students who spread these ideas globally, ensuring that fundamental research in solid-state physics continues to drive innovation.
