Tapered oxide
WebJul 14, 2000 · We find that tapered oxides reduce diffraction loss through two separate physical phenomena: (1) a reduction in transverse confinement yielding a flatter phase front, and (2) an effective lens which acts to refocus the naturally diffracting wave front. WebAug 13, 1997 · Abstract: In summary, a tapered oxide layer positioned at a field null produces reduced optical confinement and optical loss, in spite of large thickness, and maintains efficient electrical confinement.
