Title: Laser chip carrier and laser module
Inventor: KITAJIMA HIDEAKI
IPC: H01S5/022
Filed: 2002-09-25
Abstract: <P>PROBLEM TO BE SOLVED: To shorten a bonding wire for connecting a chip carrier with a wiring member.  <P>SOLUTION: The chip mounting face 12a of a chip carrier 12 is inclined to the bottom face of the chip carrier. A laser chip 10 is arranged at the center of the chip mounting face 12a. The height of an optical axis 5 of the laser chip is made different from the height of the edge 12d of the chip carrier. The height of the edge 12d is almost the same as the height of the upper face 20a of a wiring member 20. Thus, conductor patterns 12b and 12c of the chip mounted face 12a and conductor patterns 22a and 22b of the wiring member 20 are bonded with short wires 24a and 24b. The conductor pattern of the wiring member is connected to a signal input pin 26. A driving current signal can be supplied through the signal input pin to the laser chip. The bonding wire is short so that the inductance of a driving current path can be suppressed, and the deterioration of an output optical signal can be prevented.  <P>COPYRIGHT: (C)2004,JPO
