Rapid evaluation of gain spectra from measured ASE spectra of travelling-wave semiconductor optical amplifier

Small signal gain (SSG) spectra of travelling-wave semi conductor optical amplifier (TWA) are usually obtained from the ratio of amplified signal power to the input sig nal power for one by one wavelength at different injec tion currents. This conventional measuring method i not only tedious but also restricted by the wavelength range of external laser source. Amplified spontaneou emission (ASE) spectra are good sources of optical gain information. A method was introduced by Hakki-Paol (H…
