Abstract: | In this letter we present a right‐angle‐bent coplanar waveguide (CPW) which we developed for the application of the driver amplifier‐integrated (DAI) 40 Gbps traveling wave electroabsorption modulated laser module. The developed CPW realized parallel progression of the radio frequency (RF) and light using a dielectric overlay structure and wedge bonding on the bending section. The measured S11 and S21 of the developed CPW were kept below ?10 dB up to 35 GHz and ?3 dB up to 43 GHz, respectively. These measured results of the CPW were in good agreement with the simulation results and demonstrated the applicability of the CPW to the 40 Gbps communication module. |
