Nano-Thin 2D Axicon Generating Nondiffracting Surface Waves

Hans Peter Herzig, Myun Sik Kim, Elsie Barakat, Richa Dubey

We investigate nondiffracting surface waves. On top of the Bloch surface wave platform, a 60-nm-thick TiO2 isosceles triangle serves as a 2D axicon. Scanning near-field microscopy measurements verify nondiffracting surface beam properties. ...

Observation of Axial Phase Evolution of Highly Confined Light Fields

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

Highly confined light fields demonstrate peculiar phase features, e.g., Gouy phase anomaly. Longitudinal-differential phase measurements by a high-resolution interference microscope are applied to investigate phase evolutions of confined light fields for p ...

Measurements of light fields emerging from fine amplitude gratings

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

High resolution amplitude and phase of light fields emerging from a 2-μm-period amplitude grating are measured for different wavelengths. The amplitude gratings lead to highly periodic patterns caused by the Talbot effect. Such patterns reach periodicities ...

Interferometric study on Gouy phase anomaly of microlens array

Hans Peter Herzig, Toralf Scharf, Wilfried Noell, Myun Sik Kim

We investigate the Gouy phase anomaly of light in the focus of refractive plano-convex microlens arrays by using longitudinal-differential (LD) interferometry and a finite-difference time-domain (FDTD) simulation. We put emphasis on determining the amount ...

Experimental and theoretical investigation on the misalignment tolerance of a micron-sized solid immersion lens tolerance of a micron-sized solid immersion lens

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We report an experimental and theoretical study on the alignment error tolerance of a 2 µm-size solid immersion lens (SIL) illuminated by different types of focused spots. Tightly confined focal spots are of great interest for improving the performance of ...

Generation of highly confined optical bottle beams by exploiting the photonic nanojet effect

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We report on the generation of photonic nanojets, which resemble optical bottle beams. They are realized by manipulating the illumination of dielectric microspheres. As illumination we use the outer region of deliberately truncated Bessel-Gauss beam or a f ...
