英文摘要 | PURPOSE:To reduced absorption loss for laser oscillation wavelength, and obtain a single vertical mode semiconductor laser wherein threshold current is small, oscillation efficiency is high, and temperature stability is excellent, by setting the forbidden bandwidth of an active layer turning to a host crystal wider than the bright line energy of bright line source impurity, and arranging closely a carrier injection layer whose forbidden bandwidth is narrower than the bright line energy. CONSTITUTION:An active layer 4 is added with bright line source impurity with atomic radiation, and the forbidden bandwidth is set wider than the bright line energy of the bright line source impurity. Between two clad layers 2 and 5, a carrier injection layer 3 is arranged, whose forbidden bandwidth is narrower than the bright line energy of the bright line source impurity. In this constitution, when carrier is injected from the outside, positive hole is injected from the P-type InP 5 side into an active layer 4 to fill the acceptor level Ea, and electron is injected from the N-type InP 2 side into the carrier injection layer 3. Electron injected into the carrier injection layer 3 recombines with hole of Ea and vanishes to radiate a light corresponding to the bright line of Er. |
