<p><P>PROBLEM TO BE SOLVED: To provide an optical system of which the dependence of wavelength on temperature is small. <P>SOLUTION: An optical system (10) for producing modulated light is provided. A representative optical system incorporates an electron emitter (150) and an electrical-to-optical converter (160). The electron emitter is operative to produce electrons. The electrical-to-optical converter is operative to receive electrons and convert the electrons into light. The optical system modulates the light so that modulated light is emitted. Methods and other optical systems also are provided. <P>COPYRIGHT: (C)2004,JPO</p> |
