  • Tunable laser technology and Its application in optical fiber communication
    Tunable laser technology and Its application in optical fiber communication
    There are three kinds of control technologies in tunable laser: current control technology, temperature control technology and mechanical control technology. Among them, the electronically controlled technology realizes wavelength tuning by changing injection current. It has ns-level tuning speed and wide tuning bandwidth, but its output power is small. The main electronically ...
