    The difference between polarization maintaining fiber and single mode fiber
    Polarization maintaining fiber is a special type of fiber that can maintain the linear polarization characteristics of linearly polarized light during fiber transmission, suitable for situations where the linear polarization state of the optical signal needs to be maintained. Single mode fiber is a type of fiber that can transmit a single optical mode with minimal transmission ...

  • Ultrafast amplifier
    Ultrafast amplifier
    Definition: An amplifier that amplifies ultrashort optical pulses. Ultrafast amplifiers are optical amplifiers used to amplify ultrashort pulses. Some ultrafast amplifiers are used to amplify high repetition rate pulse trains to get very high average power while the pulse energy is still at moderate levels, in other cases lower repetition rate pulses get more gain and get very ...
