Simultaneous mode selection and pulse compression of gain-switched pulses from a Fabry-Perot laser using a 40-mm chirped optical fiber grating

Simultaneous pulse compression and mode selection of gain-switched pulses from a Fabry-Perot semiconductor laser are demonstrated using a chirped optical fiber Bragg grating, which has transformed initially chirped 60-ps pulses from an inexpensive multimode laser into a train of 12-ps single-mode pulses with a side-mode suppression ratio of 15.2 dB.<<ETX>>
