SEMICONDUCTOR OPTICAL ELEMENT

摘要

PURPOSE:To provide a blue semiconductor optical element oscillating at a high temperature higher than a room temperature. CONSTITUTION:In a semiconductor optical element containing either Zn or Cd as group II element, composed of a compound semiconductor containing either S or Se or Te as group VI element and having a double-heterostructure containing an active layer 4 and clad layer 6, a part of the clad layer 6 or optical confinement layer 5 is provided with a multiple quantum barrier structure 8 using a strain superlattice layer and having the function of reflecting an incident carrier as wave motion and in the manner of entering a phase where an incident wave and reflected wave intensify each other.
