Accelerated service life tests on injection lasers and transmitter modules

P. G. Eliseev, A. A. Kochetkov


Abstract: An analysis is made of the possibility of estimating reliably the service life of injection lasers from the results of accelerated tests carried out at elevated temperatures. An expression is obtained for the test acceleration coefficient under the following assumptions: the distribution of the initial parameters of the investigated lasers is described by the normal law; the distribution of failures under test is described by the logarithmic-normal law; the influence of temperature may be described by a thermally activated dependence. The efficiency of screening tests for the rejection of potentially unreliable samples is discussed and the possibility of finding an informative parameter suitable for the forecasting of service life is considered. The results obtained can be applied to accelerated service life tests on transmitter molecules.
