Ga(NAsP) multi quantum well heterostructures were grown pseudomorphically on exactly oriented (001) silicon substrates without the formation of misfit dislocations. Optical pumped lasing operation was observed at temperatures up to 125 K.
Nowadays silicon photonics gains more and more interest especially for the future architecture of Si based optoelectronic integrated circuits (OEI C). OEIC building blocks such a s modulators, detectors as well as light wave guides have been demonstrated in a down-scalable process technology. However, a commercial solution for the monolithic integration of long-term stable laser diodes has not been...
We report lasing of optically pumped Ga(NAsP)/(BGa)(AsP) heterostructures grown lattice-matched on Si. Modal gain of up to 80 cm-1 is determined at 300 K and a distinct threshold behaviour and mode spectrum is observed up to 100 K.
The focus of the present study is the optical characterisation of the novel direct band gap material Ga(NAsP) monolithically grown on Si substrate. Ga(NAsP)/(BGa)(AsP) multi-quantum-well heterostructures (MQWHs) were deposited by low temperature metal organic vapour phase epitaxy (MOVPE) in a commercial reactor system on nominally exact (001) Si substrates. In order to realise III/V laser diode the...
