Abstract
A TO can-type optical module for ultrahigh-speed communication including a laser diode chip for at least 5 Gbps. A substrate for transmitting a signal to a laser diode chip is formed by coupling an upper substrate () on which line patterns for transmission are formed, to a lower substrate () of which an upper surface has conductivity with the upper substrate () such that the optical module for ultrahigh-speed communication has single ended impedance of 25 ohms or differential ended impedance of 50 ohms. The substrate has a height of about 0.4 mm to which a laser diode chip, for ultrahigh-speed communication, is attached to enable an optical coupling between the laser diode chip, the lens, and the like, and may implement a hight-speed transmission line using a width of 0.6 mm or less thereby providing a substrate which is effectively embedded ina TO can-type package with a narrow mounting area.
