Abstract
A method for selecting a semiconductor laser exhibiting a desired relaxation oscillation frequency, including the steps of: (a) finding a correlation between a visibility of interference fringes of laser light generated by a sampled semiconductor laser and a relaxation oscillation frequency of the sampled semiconductor laser; and (b) measuring a visibility of interference fringes of laser light generated by each of semiconductor lasers to be subjected to selection and finding a relaxation oscillation frequency of that laser from the visibility thus measured with use of the correlation. This method is capable selecting semiconductor lasers exhibiting optimal high speed response characteristics for optical communications with less cost, avoiding a decrease in productivity for such lasers, and contributing to mass productivity therefor.
