Zero chirp asymmetric Fabry-Perot reflection electroabsorption modulator using coupled quantum well active region

Summary form only given. We discuss the experimental creation of asymmetric Fabry-Perot reflection modulators, which incorporate coupled quantum wells in the active region (cavity); yielding pure amplitude reflection modulators with a zero chirp parameter over the entire voltage swing (5 V bias). The asymmetric coupled quantum wells modulate absorption via the spatial separation of carriers [oscillator strength modulation (OSM)] which allows large changes in absorption with zero change in refractive index during switching.
