Function of laser driver
In optical fiber communication, optical module plays a very important role. Laser driver used on the front end of optical emission can realize the laser bias and modulation. High speed voltage signal is converted into high speed current signal to modulate laser.
Actually, a laser driver is a kind of high speed switching current and its function mainly has the following several parts: (1) high speed modulation circuit; (2) high speed bias current driving circuit; (3) automatic power control circuit.
Our company specializes in researching and producing laser drivers. In order to meet customers’ different design demands, we have designed many kinds of laser drivers, such as high voltage constant current laser driver, low noise constant current laser driver, dual mode laser driver, AC input high current high efficiency, and so on. These laser drivers don’t need heat sink because of their high efficiency.
