Controlling refractive index of transformation-optics devices via optical path rescaling
We present a general method of designing optical devices based on optical conformal mapping and
rescaling the optical path along a given bunch of rays. It provides devices with the same functionality
as those ...
Design and simulation of polarization transformers using transformation electromagnetics
In this paper we design polarization transformers using transformation electromagnetics
method. We introduce a new coordinate transformation that by compressing or expanding
the space, creates a desired delay ...
Non-reflecting non-magnetic homogeneous polarization splitter and polarization deflector design based on transformation electromagnetics
In this paper, a non-reflecting non-magnetic homogeneous polarization splitter and polarization deflector design method is proposed and investigated. Transformation electromagnetics is used as a powerful tool to achieve a ...
Reflectionless compact nonmagnetic optical waveguide coupler design based on transformation optics
The design of an optical waveguide coupler has several challenges, such as reflection losses at the interfaces of the coupler, material complexity for optical applications, and the coupling between arbitrary materials at ...
Design of reflectionless non-magnetic homogeneous polarization splitters with minimum anisotropy based on transformation electromagnetics
Design and realization of polarization splitting devices present several common challenges. Unwanted reflections from boundaries of the device and material anisotropy are among the major ones. We present a transformation ...
Reflectionless design of a nonmagnetic homogeneous optical waveguide coupler based on transformation optics
In this paper, we propose a reflectionless design of an optical waveguide coupler that is nonmagnetic and homogeneous. The coupler is designed using the linear coordinate transformation of triangles from virtual space to ...
Design of polarization splitting devices with ideal transmission and anisotropy considerations
In this paper, we introduce the generalized design of nonmagnetic homogeneous polarization splitting devices (polarization deflector/lateral shifter) based on linear area-preserving transformations for an arbitrary incident ...
Transformation optics for perfect two-dimensional non-magnetic all-mode waveguide couplers
Here, we demonstrate that transformation optics can be used to produce 2-D
non-magnetic waveguide couplers with no reflections. Our approach consists of using a scaling
function for reflection suppression and ...
Elliptical generalized Maxwell fish-eye lens using conformal mapping
A circular graded index lens is conformally transformed to an elliptical shape using a closed-form transformation. The proposed transformation is then employed to compress a Maxwell fish-eye and its generalized version. ...
Design of Nonmagnetic All-mode Waveguide Coupler with Perfect Transmission Using Transformation Optics
Using the transformation optics method together with the basic properties of Maxwell equations, a compact nonmagnetic waveguide coupler is designed that can ideally couple all TMn modes. Two compression functions are ...
