Ray-optical transformation optics with ideal thin lenses makes omnidirectional lenses
Optics Express, 2018 We present the theory of ray-optical transformation optics (RTO) with ideal thin lenses and show that ideal-thin-lens RTO devices are omnidirectional lenses.

Transformation-optics modeling of 3D-printed freeform waveguides. [PDF]
Optics Express, 2022 Multi-photon lithography allows us to complement planar photonic integrated circuits (PIC) by in-situ 3D-printed freeform waveguide structures. However, design and optimization of such freeform waveguides using time-domain Maxwell's equations solvers ...

Gain-assisted transformation optics
Optics Express, 2011 Loss severely degrades the cloaking effect of the device designed by traditional transformation. In this letter, we propose gain-assisted transformation optics to overcome the loss problem by introducing gain media into a spherical cloak. The gain media, which can amplify the electromagnetic fields, is controlled precisely to compensate the inherent ...

Broadband continuous supersymmetric transformation: a new paradigm for transformation optics
eLight, 2022 Transformation optics has formulated a versatile framework to mold the flow of light and tailor its spatial characteristics at will. Despite its huge success in bringing scientific fiction (such as invisibility cloaking) into reality, the coordinate ...

Transformational Plasmon Optics [PDF]
Nano Letters, 2010 Transformation optics has recently attracted extensive interest, since it provides a novel design methodology for manipulating light at will. Although transformation optics in principle embraces all forms of electromagnetic phenomena on all length scales, so far, much less efforts have been devoted to near-field optical waves, such as surface plasmon ...
