ABSTRACT:
An optical semiconductor device comprises a first material layer having a first thickness and formed of a first semiconductor material having a first band gap; a first quantum level pair formed in the first material layer in correspondence to the first thickness with a first energy gap that corresponds to an energy of the incident optical beam to be modulated; a pair of second material layers each having a second, smaller thickness chosen to cause the tunneling of carriers through the second material layer, the second material layer being formed of a second, different semiconductor material having a second, larger band gap and provided at both sides of the first material layer; a third material layer having a third thickness larger than said first thickness and provided at least above or below the second material layer; a second quantum level pair formed in the third material layer in correspondence to the third thickness with a second energy gap that is smaller than the first energy gap; and a carrier annihilating part for annihilating the carriers from the second quantum level pair by inducing a stimulated emission of light having an energy identical with the second energy gap.
