Abstract
The provision of a coplanar waveguide coupled with a microstrip line with a transmission line substrate that is used between two functional units of different impedance characteristics allows the input and output impedance matching to be performed, the impedance matching between which coplanar waveguide and microstrip line is performed by the variation of the signal linewidth. It allows the transmission characteristics of the optical transmission device in high frequency band to improve.
