||In this thesis, we proposed the design of optical interconnect transceiver based on glass interposer and applied for High Definition Multimedia Interface (HDMI). The VCSELs, PD, VCSELs Driver IC, TIA, 45° micro-reflector and polymer waveguides will be integrated on glass interposer. The VCSELs, PD and Driver IC, TIA connecting with each other using high-frequency transmission lines and integrated on one side of glass interposer by flip-chip packaging. Polymer waveguides package on another side of glass interposer.|
The simulation result of maximum optical coupling efficiency is 57.68 % at optical system of transmitting end and 59.62 % at optical system of receiving end. The alignment tolerance at -1 dB level for VCSEL and PD are larger than 9 m, MMF are larger than 13 m at TOSA and ROSA. The optical crosstalk between each channel is smaller than -44 dB at TOSA and ROSA.
Design of high-frequency transmission lines on glass interposer is proposed. According to the simulation result, design of single-ended and differential-pair transmission lines for TOSA and ROSA. Single-ended transmission lines at 0~62.5 GHz, return loss is smaller -20 dB and insertion loss larger than -0.2 dB for each channel. Differential-pair transmission lines at 0~50 GHz, return loss is smaller than -10 dB and insertion loss is larger than -1.5dB for each channel.
Design of differential–pair transmission lines on printed circuit board (PCB) is proposed. According simulation result, differential-pair transmission lines at 0~7.5 GHz, return loss smaller than -8 dB and insertion loss larger than -2 dB for each channel. Simulation of transmission lines when optical interconnect transceiver flip-chip packaging on PCB, return loss is smaller than -7 dB and insertion loss is larger than -2 dB for each channel.
