Method of mode detection and control in semiconductor lasers |
摘要 |
A method of controlling the spatial mode of the output of a semiconductor laser including the steps of monitoring above threshold spontaneous emissions of a semiconductor laser. Identifying a point at which the rate-of-change, or the slope, of spontaneous emissions versus drive current abruptly changes. Employing feedback to maintain spatial mode control.
