Design and Implementation of a High-Coupling and Multichannel Optical Transceiver With a Novel Packaging Structure

Short-reach optical interconnection mainly focuses on the power consumption, the cost, and the volume. According to these requirements, the design and implementation of a multichannel transceiver are presented in this paper. In this paper, a high-coupling method without the 90° beam deflection is proposed so as to reduce the total power consumption to 0.9 W. Moreover, only the mature and low-cost packaging methods such as wire bonding and flip chip are adopted to satisfy the requirement of the optical coupling, which reduces the cost. Finally, the designed transceiver retains a small size of $28\times 16 \,\, \times $ 3 mm

. To ensure normal function of the transceiver, the organic substrate is carefully designed, and the post-design simulation is conducted to characterize the electrical performance. At last, the test results show that the optical transceiver with this novel packaging structure is able to transmit the data at 10 Gb/s per channel successfully.
