A modulation depth of 40% (0.7 dB/µm) was obtained with an infrared (10.6 µm) modulator consisting of a stack of 50 pairs of weakly coupled asymmetric quantum wells monolithically integrated with a quantum well infrared photodetector. The monolithic integration is shown to be a promising technique for the "ac" coupling of infrared focal-plane arrays as well as for the direct study of the effects of electric fields and charge density variations on intersubband transitions.
