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 ...

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 ...

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 ...

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 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 ...

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 ...

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 ...

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 ...

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. ...

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 ...
