碩士 === 國立中央大學 === 光電科學與工程學系 === 103 === In the thesis, the high-frequency transmission line is designed and realized on the glass for the connection of vertical-cavity surface-emitting laser (VCSEL) and photo-detector (PD). The optical signal emitting from the VCSEL will out-of-plane couple into the polymer waveguide through the glass substrate and the polymer-based 45°reflector. The measured return loss (S11) and insertion loss (S21) of transmission lines are about -20 dB and -0.24 dB, respectively when the operating frequency is up to 50 GHz. For the optical characteristics of this optical interconnect module, the measured optical coupling efficiency for the transmitter and receiver of the flexible printed circuit board are 75%, and 60 %. The inter-channel crosstalk for both transmitter and receiver can be less than -25dB. The 10-Gbit/s eye pattern with the signal-to-noise ratio (SNR) more than 4 for the optical interconnect module is experimentally demonstrated when the bias current of VCSEL is 6 mA. and when the reverse bias voltage of PD is 2 volts.
