摘要
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 1.55 m monolithic integration DFBLD/EA grown with MOCVD and the test results in WDM system. The fiber output power2.5 mW with If =75 mA, SMSR>35 dB and the extinction ratio of 14 dB is achieved at -2.5V bias voltage under the condition of DC. No bit error appears after a transmission through 240 km fiber with bite rate 2.5 Gbit/s in WDM system. The channel penalty is 1dB BER = 10-12.
