High-Power Intrastep Quantum Well Electroabsorption Modulator Using Single-Sided Large Optical Cavity Waveguide

A novel electroabsorption modulator (EAM) using intrastep quantum wells (IQWs) and a single-sided large optical cavity waveguide is demonstrated to operate at up to 100 mW of input optical power. When the IQW EAM with uncoated facets is tested in an analog fiber link, the radio-frequency link gain reaches 16.1 dB at 100-mW optical power. We have measured a single-octave spurious-free dynamic range (SFDR) of 121 dB Hz4/5 and multioctave SFDR of 110 dB Hz2/3 for this EAM
