Abstract
A narrow spectrum transmitter based on a directly modulated DFB laser and FM to AM conversion in a common path interferometer has been investigated theoretically and experimentally. The DFB-LD is locked to the interferometer with a new pattern independent locking scheme in order to give a high extinction ratio of the ASK signal. Experimentally a -20 dB spectral width of 7. 5 GHz 0. 06 nm for a 2. 5 Gbitls ASK signal was obtained using an interferometer with an extinction ratio in excess of 25 dB. The transmitter performance was tested in a direct detection system giving a receiver sensitivity of -28 dBm. I.
