| Title: | Generation of continuous wavelength-tunable optical short pulses with two Fabry–Pérot laser diodes in an external injection-seeding scheme | Authors: | Wang, D Fang, X Jin, W |
Issue Date: | 1-Apr-2005 | Source: | Journal of the Optical Society of America B : optical physics, 1 Apr. 2005, v. 22, no. 4, p. 917-921 | Abstract: | We have developed an external-injection seeding system to generate continuous wavelength-tunable optical short pulses with a side-mode suppression ratio of more than 28 dB over a wavelength-tuning range of 21.2 nm. The system consists of two Fabry–Pérot laser diodes, one of which is gain switched and another that is dc biased; two tunable optical filters; an erbium-doped optical-fiber amplifier; and a circulator. The system is simple, easy to operate, and robust and may be used in wavelength-division-multiplexed optical-communication systems and in time-division multiplexing of spectroscopic gas sensors. | Keywords: | Chemical sensors Fiber lasers Optical communiction Optical filters Semiconductor lasers Time division multiplexing Waveguide circulators Wavelength division multiplexing |
