We propose an advanced structure of optical coupling which realizes high coupling efficiency and simplifying alignment, enabling the application of optical interconnect. A high-efficiency optical transmitter module based on this advanced coupling was fabricated using a VCSEL array. The VCSEL was directly bonded on bracket which is pasted on a holder with two pin used to locate. And there is a dummy club at the middle of the package for laser driver, favorable for cooling and reducing the noise caused by ground return. Coupling component were fabricated. And bending loss was tested. A successful eye diagram at the speed of 3.3Gb/s/ch with 850 nm was accomplished from the VCSEL-directbonded transmitter module.
