    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 ...

    High Density Fiber Management is Faced with Two Difficulties of Protection and M...
    ADSL broadband based on telephone lines has been gradually replaced by "optical fiber into the home". The data center wiring system is also increasingly using optical fiber network. "Optical copper retreat" has become the trend of data center construction. According to the survey report, the number of optical fiber ports has exceeded the number of copper cable ports in data cen...

    New Progress in Silicon Applications
    Femtosecond lasers have made breakthroughs in their structural inability to deal with bulk silicon. The use of extreme NA values allows laser pulses to achieve sufficient ionization to destroy chemical bonds in silicon, leading to permanent structural changes in silicon materials.

  • Optical direct modulation and external modulation
    Optical direct modulation and external modulation
    Direct modulation of semiconductor lasers is to modulate the laser by superimposing the pre-modulated (AM, FM, PCM) signal current on the bias current of the laser. Because it is to change the intensity of light, it is also called intensity modulation. For digital transmission, although the speed is very high, only two working states of optical signal or non-optical signal are ...
