QUANTENKASKADENLASER UND VERFAHREN ZU SEINER HERSTELLUNG

The laser has a heat generating active zone (25) made from a semiconductor material with high crystalline order and an insulating and heat dissipating zone (27) adjacent to the active zone. The zone (27) is made from an electrically insulating, heat conducting material that is identical to the semiconductor material in its chemical constituents. Electrically insulating characteristics of the heat conducting material are based on a level at a crystalline order. The zone (27) is applied under interconnection of an amorphous layer (20). An independent claim is also included for a method for manufacturing a semiconductor laser.
