Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In this paper, the authors present a new theory that can be applied to predetermine the value of cutoff temperature of operation (T) of uncooled semiconductor laser diodes. T is defined as the value of temperature of operation above which, the turn-on time delay t of uncooled SLD will exceed the bit time interval of the injected pulse and results in an inoperable case. An analytical model is derived to represent the temperature dependence of t. This model is used to derive an accurate one for T and in terms of laser cavity parameters. Simulation results show that T can be increased (improved) by increasing the injection current or biasing the uncooled SLD near threshold. The benefit of this study is that the designer could predetermine previously the requirements that should be taken into account, when considering of uncooled SLD in high-speed optical communication systems. © 2010 EDP Sciences.
