  • Abstract
    Measurements are reported of intervalence band absorption (IVBA) coefficient k0 in three types of active layer structure: bulk, unstrained (MQW) and strained multiquantum wells. The IVBA measurements are performed by observing the spontaneous emission from the uncleaved facets of DCPBH Fabry-Perot lasers. k0=(3.7+or-0.3)*10-17 cm2 is obtained for bulk, (1.4+or-0.2)*10-16 cm2 for MQW unstrained and (3.5+or-0.3)*10-17 cm2 for strained MQW structures.
