We present all-optical tuning and switching of a microcavity inside a two-dimensional photonic crystal waveguide. The photonic crystal structure is fabricated in silicon-on-insulator using complementary metal-oxide semiconductor processing techniques based ...
An improved technique for chromatic dispersion measurements in single-mode fibers using phase-shift measurements is presented. The conventional experimental setup using a modulated light-emitting diode filtered by a monochromator as a light source, a fast ...
Permanent Bragg gratings in monomode optical fibers are obtained by irradiation through an interference pattern of an ultraviolet laser. The main parameters of such gratings, in particular the index modulation amplitude and their length, are precisely dete ...
Nanostencil lithography is a flexible, rapid and resistless patterning method based on a high-resolution shadow mask. It allows for a wide choice of materials and surfaces to be structured and on the contrary to deep-ultraviolet (DUV), x-ray, electron beam ...
After microelectromechanical systems (MEMS) devices have been well established, components of higher complexity are now developed. Particularly, the combination with optical components has been very successful and have led to optical MEMS. The technology o ...
