Journal ArticleDOI
Reformulation of the Fourier modal method with adaptive spatial resolution: application to multilevel profiles.
Tuomas Vallius,Marko Honkanen +1 more
TL;DR: The eigenvalue problem in homogeneous regions demanded in the original formulation of the Fourier modal method with adaptive spatial resolution is evade, using a slightly reformulated representation for the spatial coordinates.
Journal ArticleDOI
Rotating optical fields: experimental demonstration with diffractive optics
Pertti Pääkkönen,Jari Lautanen,Marko Honkanen,Markku Kuittinen,Jari Turunen,Svetlana N. Khonina,Victor V. Kotlyar,Victor A. Soifer,Ari T. Friberg +8 more
TL;DR: In this article, Lohmann-coded binary-phase diffractive elements with restricted amplitude recording are fabricated by electron beam lithography and reactive ion etching, and the experimental results are in good agreement with theory.
Journal ArticleDOI
Generation of rotating gauss—Laguerre modes with binary-phase diffractive optics
Svetlana N. Khonina,Victor V. Kotlyar,Victor A. Soifer,Marko Honkanen,Jari Lautanen,Jari Turunen +5 more
TL;DR: In this paper, the authors demonstrate the rotation of multimodel Gauss-Laguerre beams generated with a binary-phase diffractive element, which is designed with the use of an iterative procedure and quantized in two levels after adding a carrier frequency to the phase.
Journal ArticleDOI
Deterministic Diffractive Diffusers for Displays
Marko Parikka,Terho Kaikuranta,Pasi Laakkonen,Jari Lautanen,Jani Tervo,Marko Honkanen,Markku Kuittinen,Jari Turunen +7 more
TL;DR: A LCD backlighting device that uses a diffractive light extractor that illuminates the LCD uniformly by modulation of the diffractive structure as a function of position is used to control the output field of this extended planar light source.
Journal ArticleDOI
Tandem systems for efficient generation of uniform-axial-intensity Bessel fields
Marko Honkanen,Jari Turunen +1 more
TL;DR: In this article, a beam former and an aberration corrector combined with a nonlinear axicon are designed for the transformation of Gaussian beams into Bessel fields with uniform axial intensity over a specified line segment.
