Piezoelectric MEMS Phase Modulator for Silicon Nitride Platform in the Visible Spectrum
Firehun T. Dullo, Paul C. Thrane, Nikhil Jayakumar +4
Active photonic integrated circuits (PICs) in the visible spectrum are essential for on-chip applications, requiring low-loss waveguides with broad transparency and efficient, low-…
Metasurface Polarimeter for Structural Imaging and Tissue Diagnostics
Paul Thrane, Chao Meng, Alexander Bykov +5
Histopathology, the study and diagnosis of disease through analysis of tissue samples, is an indispensable part of modern medicine. However, the practice is time consuming and labo…
Metasurface lens that is converging or diverging depending on transmission direction enables ultra-compact MEMS tunable reflective lens
Firehun Dullo, Jesil Jose, Gregory Bouquet +2
A conventional refractive lens surface can act as a positive (converging) or negative (diverging) lens, but the same surface cannot act as both. We show that a geometric phase meta…
MEMS-tunable dielectric metasurface lens using thin-film PZT for large displacements at low voltages
Christopher A. Dirdal, Paul C. V. Thrane, Firehun T. Dullo +3
Tunable focusing is a desired property in a wide range of optical imaging and sensing technologies but has tended to require bulky components which cannot be integrated on-chip and…
Dynamic MEMS-based optical metasurfaces
Chao Meng, Paul C. V. Thrane, Fei Ding +5
Optical metasurfaces (OMSs) have shown unprecedented capabilities for versatile wavefront manipulations at the subwavelength scale, thus opening fascinating perspectives for next g…
Towards High Throughput Large Area Metalens Fabrication using UV-Nanoimprint lithography and Bosch Deep Reactive Ion Etching
Christopher A. Dirdal, Geir Uri Jensen, Hallvard Angelskår +3
We demonstrate the fabrication of diffraction-limited dielectric metasurface lenses for NIR by use of standard industrial high throughput silicon processing techniques: UV Nano Imp…
