We show that a novel material InNAsP grown on InP is superior for long-wavelength microdisk lasers (and so expected for edge-emitting lasers) because of its larger conduction band offset from the addition of a small amount of nitrogen (0.5%-1%). The maximum temperature of operation for an InNAsP-GaInAsP microdisk laser is 70 °C, which is about 120 °C higher than that of a similar laser fabricated from GaInAs-GaInAsP. The characteristic temperature To of the former is 97 K, also higher than that of the latter.
