We tried to apply ab initio calculations oa large amorphous structrure to investigate the origine of the second harmonics generation from silica glass. We made (Ge doped) (poled) silica glass by molecular dynamics, then we calculated the change of the electronic structures of (Ge doped) (poled) silica glass under the external strong electric field. The changes of these electronic structures such as density of states and electron distribution, were small within our approximation.
