Definitions
- InGaAs as an active layer in heterostructures on GaAs is not suitable for this wavelength range because the bandgap (energy band gap) in homogeneous InGaAs layers would require such a high proportion of indium that the layer became unusable for lasers due to structural relaxation.
- heterostructures on GaAs can in principle also be used for long-wave emission if the emitting material is a potential well (quantum well) made of InGaAsN, whereby GaAs layers are mostly used as barrier layers above and below the active layer intended for radiation generation (see, for example, M. Kondow et al .: "GalnNAs: A Novel Material for Longvelength Semiconductor Lasers" in IEEE J. Select.
- Gao 97 Inn 03 Nn oi Asn, 99 is located.
- EP-A-0.896.406 is a semiconductor laser structure with an active layer from In N x As y P] __ x - y (0 ⁇ x ⁇ 1 and 0 ⁇ y ⁇ 1) between layers of Ga N x 'As y ' P] _- x '- y ' (0 ⁇ x ' ⁇ 1 and 0 ⁇ y ' ⁇ 1) are known.
- the semiconductor laser structure according to the invention is based on the knowledge that the radiation emission in a wavelength range of 1.3 ⁇ m and above can be significantly improved if the properties of the barrier layers, which limit the active layer intended for radiation generation, with respect to the m of the heterostru occurring tensions and dislocations can be set more precisely.
- material layers are present in the layer intended for radiation generation and in the barrier layers, which contain a III component, a V component and N (III and V corresponding to the groups of the periodic table of the elements).
- the emission wavelength is set with the nitrogen component m of the active layer.
- the active layer is usually highly compressively clamped because of the lattice constants of InGaAsN that are smaller than GaAs; This tension in the layer itself could only be removed by increasing the nitrogen content in this layer to approximately 1/3 of the indium content, which is not possible due to the poor results of the optical quality of the component.
- the tensioning of the material of the barrier layers 2 can be adjusted in such a way that it at least partially compensates for the tensioning of the potential well, which is generally highly compressive, which is formed by the active layer between the barrier layers.
- higher tensions in the potential well and thus greater layer thicknesses or higher indium contents
- This enables longer-wave radiation emissions than with conventional GaAs Bamers.
