Topologi rangkaian optik pasif telah diterima pakai secara meluas dalam rangkaian capaian kerana struktur rangkaiannya yang kos rendah dan fleksibel. Untuk mempromosikan lagi rangkaian optik pasif, pengurangan kos modul optik adalah kritikal. Gabungan yang agak mahal bagi diod laser maklum balas teragih berganding indeks konvensional (IC-DFB-LD) dan pengasing optik biasanya digunakan untuk rangkaian optik pasif dengan jarak penghantaran lebih daripada 30 km. Walaupun DFB-LD bergandingan perolehan (GC-DFB-LD) telah disiasat secara meluas dengan harapan dapat menghapuskan pengasing dalam modul optik, kuasa keluarannya yang terhad menghalangnya daripada penggunaan praktikal dalam rangkaian optik pasif. Dalam kertas kerja ini, kami menerangkan pembangunan GC-DFB-LD 1.31 µm dan 1.49 µm dengan kuasa keluaran tinggi dan toleransi suapan balik optik untuk modul optik bebas pengasing dalam rangkaian capaian. Degradasi hingar intensiti relatif (RIN) telah ditindas dengan baik di bawah -120 dB/Hz pada -8 dB maklum balas optik dalam julat suhu dari 0

Abstract: Passive optical network topology has been widely adopted in access networks due to its low-cost and yet flexible network structure. To further promote the passive optical networks, the cost reduction of optical modules is critical. Relatively expensive combination of a conventional index-coupled distributed feedback laser diode (IC-DFB-LD) and an optical isolator is commonly used for passive optical networks with transmission distance more than 30 km. Although gain-coupled DFB-LDs (GC-DFB-LD) have been widely investigated in the hope of eliminating the isolator in optical modules, their limited output power keeps them from practical use in passive optical networks. In this paper, we describe the development of 1.31 µm and 1.49 µm GC-DFB-LDs with high output power and optical feed back tolerance for isolator-free optical modules in access networks. The relative intensity noise (RIN) degradation was well suppressed below -120 dB/Hz at -8 dB optical feedback in the temperatures range from 0
