摘要：
A method for biasing a semiconductor laser (12) at the threshold level of the semiconductor laser (12). The method includes applying pilot tone signals having the same frequency to a bias current and a drive current of the semiconductor laser (12). A lateral detector (13) generates a photocurrent from spontaneous emissions of the semiconductor laser (12). Further, the method includes biasing the semiconductor laser (12) using a pilot tone signal of the photocurrent.
