摘　　要：An optical device,consisting of a multi-mode Fabry–Pérot laser diode(MMFP-LD)with two-stage optical feedback,is proposed and experimentally demonstrated.The results show that the single-mode output with side-mode suppression ratio(SMSR)of~21.7 dB is attained by using the first-stage feedback.By using the second-stage feedback,the SMSR of single-mode operation could be increased to~28.5 dB while injection feedback power of-29 dBm is introduced into the laser diode.In the case of up to-29 dBm feedback power,the outcome SMSR is rapidly decayed to a very low level so that an obvious multi-mode operation in the output spectrum could be achieved at the feedback power level of-15.5 dBm.Thus,a transition between single-and multi-mode operations could be flexibly controlled by adjusting the injected power in the second-stage feedback system.Additionally,in the case of injection locking,the outcome SMSR and output power at the locked wavelength are as high as~50 dB and~5.8 dBm,respectively.
