77-30569/352332 Influence of RLC laser parameters on data transmission speed in high-power optical transmitters
Engineering Education # 03, March 2012
This article describes a method of increasing the data transmission speed in open optical communication lines, namely the method of increasing the current modulation frequency of a powerful semiconductor laser. In this paper it is shown how the laser case influences the speed of data transmission; the advantage in transmission speed when using the laser in a smaller package is also shown. The authors propose new methods of measurement and calculation of the RLC laser emitter parameters; equations for calculation of the RLC-parameters with known values of the impedance, as well as the calculated values of RLC parameters for two investigated lasers are also given in the article. Quantitative estimations of the influence of RLC parameters on the bandwidth of the laser are included in the conclusion.
