Abstract
A light generating modulecomprises a housinga semiconductor light-emitting devicea driving elementand a monitoring light-receiving deviceThe monitoring light-receiving deviceis optically coupled with the semiconductor light-emitting deviceThe driving elementdrives the semiconductor light-emitting deviceThe housingcontains the semiconductor light-emitting devicethe driving elementand the monitoring light-receiving deviceThese elementsandare disposed sequentially along a predetermined axis. The driving elementis disposed between the semiconductor light-emitting deviceand the monitoring light-receiving deviceThis configuration makes it possible to dispose the driving elementclose to the semiconductor light-emitting deviceso as to achieve a transmission rate of 10 Gbps without degrading the optical coupling between the semiconductor light-receiving deviceand the semiconductor light-emitting device
