We present results of an experimental study of interwell coupling effects using asymmetric double quantum well structures under electric fields. Data were obtained by means of photocurrent spectroscopy. It was concluded that remarkable variations in both energy and intensity of excitonic transitions, which were observed for the strongly coupled quantum wells, originate from the intersection of two quantized levels in the conduction band.
