Programmable photonic nanojets via phase-only time-reversal: a numerical study
Tobias Abilock Mikkelsen, Cristian Placinta, Jesper Glückstad +1
We present a phase-only time-reversal framework for steering photonic nanojets without mechanical motion or amplitude modulation. Time-reversed radiation by a synthetic source plac…
Photonic nanojets as emergent free-space power flux funnels
Mirza KaramehmedoviÄ, Cristian Placinta, Tobias Abilock Mikkelsen +1
A reduced local field model derived from full-wave electromagnetic simulations shows that photonic nanojet formation corresponds to an emergent mesoscopic funnel of propagating pow…
Gabor Holography Reinvented
Jesper Glückstad
This paper presents a "reinvention" of Gabor Holography that does not suffer optically from the inherent twin-image problem originating back to Gabor's original Nobel Prize awarded…
Rethinking photonic nanojets: a new definition and design paradigm
Mirza KaramehmedoviÄ, Kristoffer Linder-Steinlein, Jesper Glückstad
We propose a rigorous, physically interpretable, and quantifiable definition of the photonic nanojet (PNJ). This framework resolves longstanding ambiguities in measuring PNJ dimens…
Lensless and Lossless HoloVAM
Andreas Erik Gejl Madsen, Jesper Glückstad
We report the first successful fabrication of three-dimensional models using our fully lensless holographic volumetric additive manufacturing (HoloVAM) platform. In this configurat…
HoloTile RGB: Ultra-fast single-shot, discretized, full-color computer-generated phase-only holography
Andreas Erik Gejl Madsen, Jesper Glückstad
We demonstrate the first use of the HoloTile Computer-Generated Holography (CGH) modality on multi-wavelength targets. Taking advantage of the sub-hologram tiling and Point Spread…
