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.
Typical telecom SOAs operate at O-band (around 1310nm) and C-Band (around 1550nm) and can provide up to ~30 dB gain, limited by ASE and strong gain saturation. Saturation and carrier‑induced refractive index changes also enable nonlinear functions such as wavelength conversion.
We offer SOAs from SemiNex with 80nm gain bandwidth centred on 1280nm:-
