Pb1-xSnxTe/PbTe1-ySeylattice-matched buried heterostructure lasers with CW Single mode output |
| |
Abstract: | The first successful realization of buried heterostructure diode lasers in the PbSnTe/PbTeSe system is reported. This has resulted in routine cw operation above 80 K with threshold currents as low as 60 mA in 5 µm wide stripe lasers. CW operation has been achieved to 120K. In addition, these lasers operate in the fundamental transverse mode up to as much as four times threshold. |
