<P>PROBLEM TO BE SOLVED: To provide an optical system which is easily adaptive to an optical communication system and has good manufacturing efficiency. <P>SOLUTION: Optical systems for producing modulated light beams are provided. A representative optical system incorporates an integrated package 120 that includes an optical source 130 and an electro-optic modulator 140. The optical source is operative to produce light that is received by the electro-optic modulator. The electro-optic modulator externally modulates the light so that a modulated light beam is emitted from the integrated package. Methods and other optical systems also are provided. <P>COPYRIGHT: (C)2004,JPO |
