“…Table 1 shows the test conditions and performance of the optical transceiver. The power consumption of the entire optical transceiver with 12 channels working at the data rate of 10.3 Gbps is about 2.4 W, less than that of the optical transceiver reported in [1], which draws about 3 W. The maximum transmission speed and data rate density of this optical transceiver is 10.3 Gbps 12 channel and 120 Gbps/810 mm 2 , respectively, similar to those of the present common high-speed optical transceivers [1][2][3]. The measured optical coupling efficiency is greater than 80% for all 12 channels, and the measured lateral fiber alignment tolerance is˙15 m for 1-dB optical coupling loss.…”

“…Parallel optical links are adapted for inter-board, inter-shelf, and inter-rack data exchange. Optical interconnection technology has progressed greatly over the past decades [1][2][3] and promises to bring future advantages to the silicon chip level [4,5]. Optical transceivers supporting the transmission speed of 10 Gbps per channel or higher have been demonstrated by several institutions [1][2][3].…”

“…However, the vast majority of current optical transceivers are faced with the problem of complex structures. A combination of 45 ı mirrors and relay lenses is widely used in current optical transceivers to realize 90 ı optical links turning, as shown in Figure 1 [1,3]. The relatively complex optical coupling structure of those Twelve-Channel Pluggable Parallel Optical Transceiver optical transceivers adds to the difficulties of the assembly process and is less favorable for mass production.…”

A novel 10-Gbps 12-channel pluggable parallel optical transceiver is designed and fabricated. Compared with other optical transceivers, this transceiver emphasizes small size, high-density, low power consumption, and high transmission speed. Most importantly, its optical coupling structure is simplified to promote costeffective large-scale production. This transceiver is electrically pluggable and consists of transmitter and receiver modules linked by parallel multi-mode fibers. Each module consists of a six-layered high-speed, high-density printed circuit board, the size of which is 30 mm 18 mm 1 mm, packaged with optoelectronic devices and corresponding control chips. The printed circuit boards not only provide a high-speed electrical connection between the I/O interfaces and high-speed chips, but they also supply power and ground planes to those chips. End-to-end error-free transmission at 10.3125 Gbps was obtained for a 2 31 1 non-return-to-zero pseudo-random bit sequence.

“…To overcome this drawback electrical interconnects are already being replaced by Active Optical Cables (AOCs) in rack-to-rack communication, while midboard optical subassemblies and compact board-level flexible modules (FlexPlane) [2] have already entered the market. Optical Printed Circuit Boards (OPCBs) are researched towards replacing electrical PCB interconnects and low-loss embedded polymer waveguide interconnects have been demonstrated to yield Tb/s on-board transmission capabilities [3]. In all this deployment, communication is realized with optical I/O's to an ASIC electronic router chip [2] that can even reach 168 bi-directional links [4].…”

In this article a parallel optical sub-system package is designed and fabricated. An 850nm vertical cavity surface emitting laser (VCSEL) array with a laser driver are used as the light sources of the transmitter, and a photodiode (PD) array with a trans-impedance amplifier plus limiting amplifier (TIA/LA) are used as the detectors of the receiver. Two chips including VCSEL array and PD array are integrated on a high impedance silicon substrate through flip-chip process. The solder bumps are planted on substrate as input and output electrical interface. Passive alignment with high coupling efficiency and large tolerance is achieved. Electrical design for high frequency and high density package is critical, due to the issues related to Signal Integrity (SI) and Power Integrity (PI). Electrical interconnection based on substrate for highspeed signal and power integrity are also analyzed. The assembly of sub-package based on silicon substrate and PCB is finished. And an 8×14Gbps SOP parallel optical transceiver is developed. The back to back eye diagram measured results shows that bit rate of each channel is able to reach up to 14Gbps. IntroductionParallel optical interconnect is a good choice to complete the short distance, high speed communication compared with copper and serial optical interconnect, and applied to meet the high bandwidth requirement of rack to rack and chip to chip. Parallel optical transmitter (TX) and receiver (RX) multi-chip module with 1310nm and 850nm wavelength has been covered. Multi-mode applications allow higher coupling tolerances that reduce the packaging costs that are quite high for photonic devices package at single-mode transmission. ASICs and microprocessors drive the need for parallel optical links for both high performance computing (HPC) in data centers and in consumer applications as high-definition multimedia interfaces (HDMI) [1][2]. This requires large bandwidths on the physical link layer. Protocol standards are evolving to meet higher performance requirements, Optical modules QSFP and CXP for Infiniband applications supporting multi-Gbps per channel have been proposed [3][4][5]. However, optical package is challenging because of combining thermal, electrical and optical design, process and reliability requirements. Generally speaking, two key parts determine the performance of an optical transceiver and cost. One is the optical design, which should provide for stable optical alignment between the electro-optic active elements and the fiber channels. The majority of current parallel optical transceivers are faced with the problem of complex structures. A combination of 45° mirrors to realize 90°optical links turning and micro lens r mounted on flexible PCB are widely
