Electromagnetic wave chaos in gradient refractive index optical cavities.
Electromagnetic wave chaos is investigated using two-dimensional optical cavities formed in a cylindrical gradient refractive index lens with reflective surfaces. When the planar ends of the lens are cut at an angle to its axis, the geometrical ray paths are chaotic. In this regime, the electromagnetic mode spectrum of the cavity is modulated by both real and ghost periodic ray paths, which als...
متن کاملTailoring of refractive index profiles in LiNbO3 optical waveguides
Proton-exchange LiNbO3 planar optical waveguides have been irradiated with swift ions (Cl 30 MeV) at very low fluences in the range 5 × 1010 − 5 × 1012 cm−2. Large modifications in the refractive index profiles, and therefore in the optical performance, have been obtained due to the generation of amorphous nano-tracks by the individual ion impacts. Moreover, a fine tuning of the refractive inde...
متن کاملHigh temperature-gradient refractive index liquid crystals.
We have analyzed the physical origins of the temperature gradient of the ordinary refractive index ( dn(o) /dT) of liquid crystals. To achieve a large dn(o) /dT , high birefringence and low clearing temperature play crucial roles. Based on these simple guidelines, we formulated two exemplary liquid crystal mixtures, designated as UCF-1 and UCF-2, and compared their physical properties with a co...
متن کاملOptical fiber refractive index profile synthesis from near field
Abstract – A new and accurate refractive index profile synthesis method for optical waveguides is demonstrated using the transmitted near electric field data. This method is based on an inverse transmission line technique. From Maxwell’s equations, we derive a transmission line equivalent circuit for the refractive index profile of a cylindrical dielectric waveguide. We demonstrate how to use t...
متن کاملPorous Silicon Gradient Refractive Index Micro-Optics.
The emergence and growth of transformation optics over the past decade has revitalized interest in how a gradient refractive index (GRIN) can be used to control light propagation. Two-dimensional demonstrations with lithographically defined silicon (Si) have displayed the power of GRIN optics and also represent a promising opportunity for integrating compact optical elements within Si photonic ...
