Optical injection locking
WebNov 22, 2024 · One of the major techniques to stabilize the frequency in semiconductor lasers is optical injection locking . We have previously reported the dynamics of semiconductor lasers under dual optical injection [15,16]. The additional signal was found to enhance the chaos and control the stability map. WebThe optical injection locking (OIL) further enhances the large-signal BW, resulting in narrower pulse width of 9.5 ps (6.2 ps after deconvolution) in the time domain and three sideband peaks above 70% from the peak in the frequency domain (full width half maximum of 130 GHz). Assuming linear chirp, the pulse could be further compressed to 2.4 ps.
