Si surface cleaning for semiconductor circuits

  Abstract: A method is disclosed for the cleaning of a Si surface at low temperatures. Oxide on the Si surface is brought into contact with Ge, which then sublimates off the surface. The Ge contamination remaining after the oxide removal is cleared away by an exposure

Silicon Photonics Chip tested in Electro-Optic Test Station

Introduction to the Integrated Photonics Laboratory

Steady progress during half a century of development in Silicon integrated circuits has resulted in fabrication techniques that allow the large scale fabrication of billions of transistors in a single chip and their miniaturization to deep submicron dimensions. The realization

Dispersion in photonic crystals

Abstract: Investigations on the dispersive properties of photonic crystals, modified scattering in ring-resonators, monolithic integration of vertical-cavity surface-emitting lasers and advanced data processing techniques for the finite-difference time-domain method are presented.Photonic crystals are periodic mesoscopic arrays of scatterers that modify
