Introduction to Semiconductor Optical Amplifiers (SOAs) This chapter is dedicated to the basics and key parameters of semiconductor optical amplifiers (SOAs). The beginning of Sect. 2.1 provides a
In general, optical gain of an optical amplifier is both a function of signal optical wavelength and the signal optical power: G = G (λ, P). In addition, when operating in room temperature, both
When the light enters FPA it gets amplified as it reflects back and forth between the mirrors until emitted at a higher intensity. It is sensitive to temperature and input optical frequency.
G is increasing with device length, however, the internal gain is limited by gain saturation. G is depended on the optical input intensity, as it increases EHP depleted from the active region.
