Optical interconnect modulesWe demonstrated the use of optical interconnection module for the assembly of OPCB having four μm height. The refractive indices of the core and the cladding are and , respectively, at 850μm in x–z axis and in y axis, respectively. Here the dimension of the waveguide is 50dB and the coupling loss between VCSELwaveguide is μm in the x–z axis and in the y axis, respectively. For example, when the position misalignment is 10μm.We conducted simulation study about the coupling efficiency between the VCSELwaveguide pair and the waveguidePD pair by ray tracing. With the variation of misalignment of x, y, and z axis we calculated the coupling efficiencies.
