Highly efficient heat extraction by double diamond heat-spreaders applied to a vertical external cavity surface-emitting laser

Highly efficient heat extraction by double diamond heat-spreaders applied to a vertical external... We compare the heat extraction efficiency for a standard Vertical External Cavity Surface-Emitting Laser and the distributed Bragg reflector (DBR)-free structure employing a single and double diamond heat-spreaders, respectively. Both heterostructures grown by Molecular Beam Epitaxy employ two identical active regions designed for emission at 980 nm. We show that the thermal resistance has been decreased 15 times when there is no DBR and heat is extracted from both side of active region. For DBR-free laser no thermal rollover of power conversion characteristic was observed in the range of considered input powers. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Optical and Quantum Electronics Springer Journals
