Quantum well-based waveguide for semiconductor lasers
  In this work we study a possibility of waveguide fabrication on the basis of active quantum wells in semiconductor lasers. The efficiency of such a waveguide for an InP structure with In0.53Ga0.47As quantum wells is demonstrated experimentally. An optically-pumped laser on this basis is realized.
