Photonic Crystal Mikaelian Lenses and Their Potential Use as Transverse Focusing Elements in Microstructured Fibers

IEEE Photonics Journal, 2013
We numerically studied the focusing properties of a special type of graded index photonic crystal media, i.e., the so-called photonic crystal Mikaelian lenses (PCMLs). We considered PCMLs with a varying air hole diameter and with a varying air hole pitch

The Acousto-Optic Effect in Microstructured Optical Fibers [PDF]

1st Workshop on Specialty Optical Fibers and Their Applications, 2008
The acousto-optic effect has been successfully used since the early 80's in the design and construction of a variety of conventional optical fiber devices such as frequency shifters, couplers, filters and modulators. Acoustic waves can be employed to modulate the spectrum and switch the wavelength of conventional fiber Bragg gratings as well as for ...
