Sferenti tippi di amplificatori sò diffirenti assai per esempiu, per esempiu, i certulini di e proprietà di saturazione. For example, rare-earth-doped laser gain media can store substantial amounts of energy, whereas optical parametric amplifiers provide amplification only as long as the pump beam is present. As another example, semiconductor optical amplifiers store much less energy than fiber amplifiers, and this has important implications for optical fiber communications. -

Ultra Compact DP-IQ Modulatore Myas Controller Automatic Cross Controller
The controller injects a low frequency, low amplitude dither signal together with bias voltage into the modulator. It keeps reading the output from the modulator and determines the condition of the bias voltage and the related error. Una nova tensione di a biasa serà applicata dopu à a misura precedente. In questu modu, u MODULUTORE hè assicuratu per travaglià in a tensione bias adattata.
