Title: Method for controlling refractive index of optical film using laser ablation and method for forming optical element
Inventor: OGOSHI MASAYUKI
IPC: C23C14/28
Filed: 2002-03-25
Abstract: <P>PROBLEM TO BE SOLVED: To form an optical element by depositing and laminating, without selecting a substrate material, a quality quartz glass (SiO<SB>2</SB>) film for which the film thickness and refractive index are controlled.  <P>SOLUTION: The depositing speed of the SiO<SB>2</SB>film is varied by the pulsed energy of a laser beam 5 that is adjustable outside a film deposition container 1, with the refractive index of the pure SiO<SB>2</SB>film continuously controlled in 10<SP>-2</SP>order. Since the depositing speed of the film is as low as 0.02-0.1 nm/pulse, the film thickness can be controlled in nanometer order by the integrated value of the laser pulse. This method is effective in manufacturing an optical waveguide element or the like. In addition, if deposited films need to have a larger difference in the refractive index mutually, the refractive index of the SiO<SB>2</SB>film can be continuously controlled by varying only the pressure of atmospheric oxygen gas inside the film deposition container 1. In this case, the refractive index can be controlled in 10<SP>-1</SP>order, which is effective in manufacturing photonic crystals, for example.  <P>COPYRIGHT: (C)2004,JPO
