Abstract:
1. An optical transmitter module with a coaxial type packaging, used to convert an electric signal to an optical signal and then transmit the optical signal, the optical transmitter module comprising: a base, having a plurality of pins; a substrate, the substrate having a plurality of electric traces on surfaces thereof; a light-emitting device having coplanar anode and cathode electrodes, the electrodes being electrically connected to the electric traces on the substrate by electrically flip-die bonded to the substrate, wherein the light-emitting device is electrically connected through the substrate to the pins of the base; and a cap, mounted on the base over the substrate to protect the light-emitting device, wherein the optical signal is transmitted by the optical transmitter module with a speed up to 10 Gbps and heat produced by the optical transmitter module is dissipated through the substrate.
