Electro-optical conversion analysis of chip-on-carrier and packaged semiconductor optical amplifiers

Experimental sweep frequency results of electro-optical conversion for a chip-on-carrier and for a packaged semiconductor optical amplifiers are presented up to the fifth harmonic. Influence from electrical bias current, spectral components, and input power are analyzed. The experimental results illustrate the influence of electrical parasitic elements in semiconductor optical amplifiers´ bandwidth and could be used for equivalent circuit parameters extraction.
