“…This embedded optical transmitter/receiver (Tx/Rx) modules provide smaller packaging, high system bandwidth, and design flexibility for the board and system level interconnect. Some institutes or companies have carried out research related to this area or even made products [9,10]. It can be used for close on-board inter-chip interconnections, as shown in Figure 1, as well as for the board edge applications.…”

The bi-directional data rate is investigated of an eight-channel 10-Gbps optical transceiver with a size of 15 mm 15 mm 6 mm and ball grid array package form that was designed and fabricated. A passive optical coupling method is designed based on a coupling lens array, which is transformed to substrate through a carrier. This electrical performance is characterized through a 3D full wave simulation and shows great advantages compared with traditional pluggable optical transceivers. Experimental eye diagram measurement in loop-back mode via a 2-m-long multimode fiber array shows an eye width of 51.984 ps at a bit-error rate order of 10 12 , which proves the transceiver's ability for 10.3125-Gbps data transmission.

The bend waveguide is one of the key components of photonic integration. In this paper, by using tightly focused femtosecond laser pulses with repetition rate of 76 MHz, pulse duration of 50 fs, average output power about 270mW, and the focus lens NA=0.65, we put forward a structure of waveguide that bent it to be 1/4 round, and research its mechanism by performing experiments. Under the above conditions, when the vertical scanning speed of the laser system is 0.8 mm / s, the width of the bend optical waveguide is about 10μm, the loss reaches a minimum value about 1dB/cm when the bend way's radius is about 5mm. Based on the experimental results of the above parameters, we can fabricate a 1/4 round vertical bend fiber coupler, which can be applied to the connection between the chips or inter-level optical .The results showed that the bend lithium niobate waveguides can be applied in the field of optical communication and has important implications for the production of low loss, low cost and small size optical waveguide gratings , vertical fiber coupler, optical switches and other devices .

We fabricated a newly designed 12-channel optical transmitter has a butt coupling possibility. An organic FR4 printed circuit board (PCB) was used as a substrate for integrating a 850 nm vertical cavity surface emitting laser (VCSEL) array with an electrical driver integrated circuit (IC). The substrate whose dimensions are 6.0 mm x 6.0 mm x 0.5 mm serves as a packaging platform which can provide the advantages of shorter signal routing, smaller size, and so on. Since the VCSEL array is attached on the sidewall of an organic substrate, this structure is the direct coupling-capable that has high optical coupling efficiency, which doesn't require 45 mirror and lens. This simple structure reduces the complexity of implementation and the cost.To analyze microwave characteristics of the optical transmitter, we have designed electrical transmission line from a driver IC to a VCSEL array. The circuit simulation was accomplished with the CST microwave studio, which uses the method of finite-difference time-domain (FDTD) algorithm for full wave electromagnetic characteristics. Through the simulation of the quasi-CPW line structure optimization, this transmission line is proved to be applicable to high frequency signal transmission. Simulation of temperature distribution in the embedded VCSEL array and driver IC modules was also achieved.The optical transmitter has been characterized using optical coupling into multimode fiber array. This transmitter showed a clear eye diagram of 5Gbps optical transmission.
