中文摘要	a novel distribute feedback (dfb) laser which gave two different wavelengths under two distinct work conditions was fabricated. the laser consists of two bragg gratings with different periods corresponding to wavelength spacing of 20 nm in an identical active area. when driving current was injected into one of the different sections separately, two different wavelengths at 1542.4 and 1562.5 nm were realized. the side mode suppression ratio (smsr) of 45 db or more both for the two bragg wavelengths were achieved. the fabricating process of the laser was just the same as that of traditional dfb laser diode. this device can be potentially used in coarse wavelength division multiplexer (cwdm) as a promising light source and the technology idea can be used to enlarge the transmission capacity in metro area network (man).
