Abstract(in English) | The application of InGaAs ternary substrates to 1.3 μm semiconductor lasers is one of the promising candidates to realize excellent temperature characteristics. We have achieved a record high characteristic temperature (T_0) of 140 K and a lasihg at 210℃ in 1.2μm strained quantum well lasers on In_<0.22>Ga_<0.78>As ternary substrates. The T_0 strongly depends on the threshold current density, which can be numerically explained by assuming a certain Auger coefficient. We have also reallzed lasing at 1.3μm by fabricating the strained quantum well lasers on In_<0.31>Ga_<0.69>As substrates. Their temperature characteristics should be further improved by fabricating lasers on quality InGaAs substrates and, then, achieving a much lower threshold current density. The application of InGaAs ternary substrates to vertical cavity surface emitting lasers (VCSELs) is also discussed. |
