The InGaAsP layers 3a form the well layers to electrons and the AlGaAsSb layers 3b form the quantum wells to holes. The wave functions of the electrons are, therefore, formed on the layers 3 and the wave functions of the holes are formed on the layers 3b. The energy difference DELTAE between the transmission band of the InGaAsP layers 3a and the valence band of the AlGaAsSb layers 3b is the energy gap to govern light absorption. The light intensity ratio at the time of on and off is lowered in this way in the optical communication of 1.5mum band.
