  • Types of optical amplifiers include

    Types of optical amplifiers include

    Semiconductor optical amplifiers (SOAs) are amplifiers which use a semiconductor to provide the gain medium. These amplifiers have a similar structure to but with anti-reflection design elements at the end faces. Recent designs include anti-reflective coatings and tilted and window regions which can reduce end face reflection to less than 0.001%. Since this creates a loss of power from the cavity which is greater than the gain, it prevents the amplifier from acting as a laser.
