By Igor Minin, Oleg Minin

In this e-book the authors current a number of examples of thoughts used to beat the Abby diffraction restrict utilizing flat and 3D diffractive optical components, photonic crystal lenses, photonic jets, and floor plasmon diffractive optics. The constructions mentioned can be utilized within the microwave and THz variety and in addition as scaled types for optical frequencies. Such nano-optical microlenses will be built-in, for instance, into latest semiconductor heterostructure structures for next-generation optoelectronic applications.

Chapter 1 considers flat diffractive lenses and leading edge 3D radiating constructions together with a conical millimeter-wave Fresnel sector plate (FZP) lens proposed for subwavelength focusing. In bankruptcy 2 the subwavelength focusing houses of diffractive photonic crystal lenses are thought of and it truly is proven that not less than 3 sorts of photonic crystal lens are attainable.

With the purpose of attaining subwavelength focusing, in bankruptcy three an alternate mechanism to supply photonic jets at Terahertz frequencies (terajets) utilizing 3D dielectric debris of arbitrary dimension (cuboids) is taken into account. A scheme to create a 2nd “teraknife” utilizing dielectric rods is additionally mentioned. within the ultimate bankruptcy the winning edition of free-space 3D binary phase-reversal conical FZPs for operation on floor plasmon-polariton (SPP) waves demonstrates that analogues of Fourier diffractive parts should be built for in-plane SPP 3D optics.<

Review

ing thought, modelling and scan, this publication might be a precious source for college students and researchers engaged on nanophotonics and sub-wavelength focusing and imaging.
