Advantages and disadvantages of semiconductor optical amplifier

Semiconductor optical amplifier is one type of laser diode without end of the mirror. it is the latest technology that provides high-speed switching capability, high extinction ratio, gain etc. Here this article gives the advantages and disadvantages of semiconductor optical amplifier to know more details about semiconductor optical amplifier (SOA).

Advantages semiconductor optical amplifier :
  • Small size
  • Electrically pumped
  • Smaller output power then EDFA
  • Less expensive then EDFA
  • It can be run with a low power laser
  • It provides all types of nonlinear operation like cross-phase modulation, cross gain modulation can be conducted
Disadvantages of  semiconductor optical amplifier :
  • Lower gain
  • High non-linearity
  • Higher noise
  • Polarization dependence
