英文摘要 | PURPOSE:To obtain a semiconductor laser oscillating in a wavelength of 2-3 mum having a wide range of operating temperatures without remarkably increasing an oscillation threshold value, by forming a part or all of at least one of two clad layers of a specific compound semiconductor layer. CONSTITUTION:On an InAs substrate, there are formed an N-type InAsPSb layer 2 as a second clad layer, an N-type InAsPSb light-emitting layer 3, a P-type A GaAsSb layer 13 as a first clad layer and a P-type InAsPSb layer 4 one over another and electrodes 5 and 6 are provided. A part or all of the clad layer 13 is provided by a tetra-or penta-component compound semiconductor layer consisting of a combination of Al, As, Sb and at least one of In and Ga. In the layer 13, crystals can be grown to a composition corresponding to a forbidden band width of about 5 eV while matching their lattices with the substrate Thus, the layer 13 is allowed to have a width of the forbidden band which is greatly different from that of the light-emitting layer 3. Therefore, if a temperature is raised, a threshold value is not increased thereby since electrons are effectively entrapped in the layer 3. |
