57AbstractABDie vorliegende Erfindung betrifft einen Diodenlaser mit einer Stromblende und insbesondere einen Diodenlaser mit einer angepassten „p-n-p"- bzw. „n-p-n"-Struktur als Stromblende zur Reduzierung der Tunnelwahrscheinlichkeit. Ein erfindungsgemäßer Diodenlaser umfasst eine aktive Schicht (16) und eine außerhalb der aktiven Schicht (16) schichtförmig ausgebildete Stromblende (30) aus einem entgegen seiner Umgebung dotierten Material für eine räumlich selektive Bestromung der aktiven Schicht (16) zwischen einem n-Substrat (10) und einem p-Kontakt (24); wobei die Stromblende (30) über eine intrinsische Außenschicht (32, 38) von angrenzenden Schichten getrennt ist.
