Title: Module for optical communication
Inventor: NONAKA TAKEHIRO
IPC: H01L31/0232
Filed: 2000-10-23
Abstract: PROBLEM TO BE SOLVED: To provide a module for optical communication which is superior in high-frequency characteristics and high in production efficiency. SOLUTION: By coupling an optical device 1 and a circuit board 11 by means of a flexible circuit board 10, the optical device 1 can be connected to the flexible circuit board without forming lead wires 2 of the optical device 1, and the production efficiency is increased. Since the optical device 1 can be connected to the flexible circuit board 10 with the lead wire side of the optical device 1 being nearly tightly adhered to the flexible circuit board 10, the length of the lead wires 2 can be the shortest to improve the high-frequency characteristics. The integral structure of the flexible circuit board 10 and circuit board 11 further increases the productivity.  An electronic device 7 such as transmission/reception IC is mounted on the light emitting device 1 side of the circuit board 11 or flexible circuit board 10, shortening the wire length between the light emitting device 1 and the electronic device 7 and thereby further improving the high-frequency characteristics.
