Latkowski, S.; Surre, F.; Landais, P.; Dublin City Univ., Dublin This paper appears in: Transparent Optical Networks, 2007. ICTON '07. 9th International Conference on Issue Date: 1-5 July 2007 On page(s): 257 - 260 Location: Rome Print ISBN: 1-4244-1249-8 INSPEC Accession Number: 9835405 Digital Object Identifier: 10.1109/ICTON.2007.4296293 Date of Current Version: 27 August 2007 Abstract Although self pulsating (SP) lasers are DC biased, they feature a modulation of the output power. For the results presented in this paper, the SP frequency corresponds to the frequency spacing between longitudinal modes or its second harmonic. The performances of both a 40 GHz self pulsating distributed Bragg reflector laser and of a 660 GHz slotted laser are presented. For the first laser, the radio frequency (RF) signal was analysed on electrical spectrum analyser and its linewidth was smaller that the sum of the main optical modes, proving a passive modelocking of the mode phases. For the slotted laser, a bolometer interfaced to a FT IR spectrometer is used for the terahertz (THz) detection. A signal 10 times larger than the noise level was measured with this set up. Both lasers have demonstrated to be an easy solution to produce RF or THz signal generator.
