Abstract

Disclosed herein is a duplicated light source module constructed so that rays of light emitted from two light sources pass through one lens and then enter one optical fiber through a birefringent element. This module is useful when a light source in an optical transmitter is intended to be duplicated or when a high-power pumping source in an optical fiber amplifier is required.
