Subwavelength engineered structures for integrated photonics

2016 Progress in Electromagnetic Research Symposium (PIERS), 2016
We report our advances in development of subwavelength engineered structures for integrated photonics. This unique technology allows synthesis of an effective photonic medium with an unprecedented control of material properties, constituting a powerful tool for a designer of photonic integrated circuits.

Femtosecond Microfabrication of Subwavelength Photonic Structures

2006 European Conference on Optical Communications, 2006
The fabrication of sub-micron photonic structures beyond diffraction limit is demonstrated by means of tightly focused laser pulses. 25 mm long periodic structure with a pitch size of 260 nm is experimentally produced. Detailed numerical modelling is performed to establish mechanisms of such inscription.

Optical Elements with Subwavelength Structured Surfaces

Optical Review, 2003
Various optical elements with subwavelength structured surfaces have been developed. The periods of the subwavelength structures are too short to generate diffracted light waves. But the structures are equivalent to refractive index materials with form birefringence.

Reflective waveplate with subwavelength grating structure

Japanese Journal of Applied Physics, 2015
A reflective waveplate with subwavelength grating structure of the photoresist was fabricated using two-beam interference technology. From the optical measurement, it is found that the phase retardation of the fabricated reflective element (period: 400 nm, fill factor: 0.5, depth: 280 nm) was almost the same as that of the transmission waveplate with ...

Subwavelength-structured antireflective surfaces on glass

Thin Solid Films, 1999
Abstract The usability of porous sol–gel coatings and periodic or stochastic subwavelength surface-relief structures for low-cost broadband antireflective (AR) surfaces on glass and on plastics was studied experimentally. Porous sol–gel coatings were produced by dip-coating on glass.

Subwavelength structures for polarization manupulation

2011
In dieser Arbeit wird die Entwicklung von Subwellenlängenstrukturen für die Polarisationsmanipulation des Licht im sichtbaren Bereich untersucht. Die Erzeugung von radial polarisiertem Licht wird als die Hauptanwendung angesehen. Weiterhin werden sie zur Gestaltung eines polarisatorarrays für die Shearing-Interferometrie eingesetzt.
