A 9pJ/bit SOP optical transceiver with 80 Gbps two-way bandwidth

The high-speed parallel optical transmitter module based on VCSEL/PD array, high-speed specialized integrated circuit, fiber array micro-optical components presents magnificent application and development potential. The coupling alignment between VCSEL/PD array and waveguide array has been reported using silicon optical bench (SiOB) [1–3]. In this paper, A passive coupling method based on SiOB and the packaging of the VCSEL/PD arrays are introduced; the coupling efficiency is about 80% with a misalignment tolerance of +/−15µm, optical cross talk is about −70dB. A silicon optical bench is fabricated as a platform for integrated photonic components. The thermal performance and electrical performance of optical sub-package is analyzed and optimized.
