Fabrication and performance analysis of a high-coupling- efficiency and convenient-integration optical transceiver

Abstract:

An optical transceiver with a novel optical subassembly structure is proposed in this paper, which achieves high coupling efficiency and low assembly difficulty. The proposed optical transceiver consumes 0.9 W power and retains a small size of 28 mm×16 mm×3 mm. The fabrication process of the silicon substrate and the assembly process of the optical transceiver are demonstrated in details. Moreover, the optical transceiver is measured in order to verify its transmission performance. The clear eye diagrams and the low bit error rate (BER) less than 10-13 at 10 Gbit/s per channel show good transmission characteristics of the designed optical transceiver.
