本文报道了采用全ＭＯＣＶＤ生长的１．５５μｍ单片集成ＤＦＢ－ＬＤ／ＥＡ组件的制作和在ＤＷＤＭ系统上的传输测试结果。出纤功率Ｐｆ≥２．５ｍＷ，Ｉｆ＝７５ｍＡ，边模抑制比ＳＭＳＲ≥３５ｄＢ。调制器反向偏压为２．５Ｖ时的消光比为１４ｄＢ；该发射模块在２．５Ｇｂｉｔ／ｓＤＷＤＭ系统上进行传输试验，传输２４０ｋｍ后无误码，其通道代价≤１ｄＢ，ＢＥＲ＝１０－１２。
This paper reports the fabrication of a 1.55μm monolithically integrated DFB-LD / EA module grown by full MOCVD and the transmission test results on a DWDM system. Fiber power Pf ≥ 2.5mW, If = 75mA, side mode suppression ratio SMSR ≥ 35dB. The extinction ratio when the modulator is reverse biased at 2.5V is 14dB. The transmitting module performs transmission test on a 2.5Gbit / s DWDM system without error after transmitting 240km with the channel cost of ≤1dB and BER = 10-12.
