چکیده
Diffractive optical elements are components relying on the physical phenomena of diffraction and interference to control the propagation of light. Such elements are usually macroscopically planar microstructures, consisting of features with dimensions from a couple of wavelengths to a few tens of microns and being designed by advanced numerical algorithms based on rigorous diffraction theory. The progress in diffractive optics is closely related to the progress in microfabrication technology. As a result, researchers working in diffractive optics are now exploring structures with features below the wavelength such as resonant grating filters, photonic crystals, plasmonic structures and microcavities [1].

Raman Spectra of a PMMA Microstructured Optical Fibre and Direct Measurement of Its Gain Coefficient
A polymethylmethacrylate (PMMA) microstructured polymer optical fiber (mPOF) is fabricated and characterized. Using the cut-back technique the fiber loss is measured which is higher than the step-index silica fibers. Through a novel experimental scheme, the backward Stokes spectrum of the fabricated mPOF is recorded over a range exceeding 3000 cm‑1 during the cut-back method and compared ...

An effective surface equation, that encapsulates the detail of a microstructure, is developed to model microstructured surfaces. The equations deduced accurately reproduce a key feature of surface wave phenomena, created by periodic geometry, that are commonly called Rayleigh-Bloch waves, but which also go under other names, for example, spoof surface plasmon polaritons in photonics. Several il...
متن کاملFuture Directions for Microstructured Polymer Optical Fibres
Microstructured Polymer Optical Fibres [MPOF] were first made in 2001, and subsequent development has aimed at exploiting the material and design opportunities they present. Most effort has been focused on developing approaches for high bandwidth MPOF, and investigating the properties of multimode microstructured fibres. We also consider new applications in endoscopy and photonic interconnects,...
