Abstract
A COB bonding laser diode interface mating device comprises a laser diode and a driver integrated circuit (). The laser diode includes a light-emitting chip (). The light-emitting chip () is a bare die directly bonded to a circuit board. The driver integrated circuit () is a driver chip that is a packaged chip. The light-emitting chip () and the driver chip are connected through a capacitor-resistor network (). The capacitor-resistor network () allows the driver integrated circuit () to provide a bias current and a modulation current to the laser diode such that the laser diode is in an activated state. The capacitor-resistor network () realizes interface mating between the COB bonding laser diode and the driver integrated circuit (), thereby solving a problem that the interface mating cannot be easily achieved, reducing costs, and improving production efficiency.
