The optical interconnection module, which includes E/O (electrical/optical) conversion unit, is attached to the OPCB with solder ball. The solder ball bonding is designed to acplish the alignment between the waveguide structure and the electric circuit with high precision. The OPCB prototype consists of main body of OPCB and two electrical subboards. The main OPCB has embedded waveguide which is the medium of optical interconnection. The two subboards are used for electricaltooptical (E/O) or opticaltoelectrical (O/E) conversion. The VCSEL array and the PD array are bonded to interconnect the waveguide to the bottom of the subboard. The driving circuits are placed on the opposite side to VCSEL array and PD array. The power, ground and other electrical control signal are supplied through the pin grid. The main OPCB is placed on the EPCB within a rectangular area of 70μm in the x–z axis and in the y axis, the coupling loss between VCSELwaveguide is mm is for alignment and the other with diameter of 200cm length. Refractive indices of the core and the cladding are and , respectively, at 850nm wavelength. Shows one of the microlensed VCSEL array and microlensed VCSEL has a microlens formed by the inkjetting method on the aperture of VCSEL. Inkjetting of UV curable resin on the VCSEL, lens material is aligned automatically on the aperture of VCSEL. Shows a view of the system where the output power from the microlensed VCSEL arrays is measured for their divergence. The divergence angle of the laser light from the VCSEL is shown to bee narrower by using microlenses by the collimating effect pf the light from VCSEL. Because of the microlens, the higher order modes from the VCSEL are suppressed by the cavity effect [10]. The emitted output from the VCSEL cavity is reflected back by microlens layer and is focused on the VCSEL cavity. During this process, the divergence angle of the VCSEL is reduced. In this case, the divergence angle of the VCSEL decreased from 18176。 slope, a thin film of SiO2 is grown on patterned waveguide. And photoresist is patterned at the end of the each waveguide structure and the ends of the waveguides are etched with KOHsaturated isopropanol solution to form 45176。 mirrorsTo use polymers as materials of the waveguide, embossing technique is used because of its relatively easy fabrication process. We fabricated polymer waveguides by UV embossing, which also involves fabrication of mold and replica. UV curable polymers are used as materials of waveguides and silicon mold is used to form waveguide patterns. For vertical coupling between VCSEL array and waveguide array and between the waveguide array and the PD array, we have to utilize mirror face at each end of the waveguide. To achieve this process, waveguide mold equipped with 45176。μm in x, y and z axis.
