Semiconductor Optical Amplifiers (SOAs) are electrically pumped semiconductor devices that provide optical gain in a travelling‑wave configuration. They operate similarly to laser diodes but use antireflection (AR) coatings and angled or curved waveguides to suppress cavity feedback. Light is amplified in the singlemode waveguide with strong overlap between the guided mode and the carrier‑injected active region.
Reflective SOAs (RSOAs), also known as "Gain Chips", use one high reflectivity facet and one AR facet, enabling double‑pass gain. they are optimised for external cavity lasers (ECLs) rather than single‑pass amplification..
