Femtosecond laser direct writing is a powerful technique for fabricating micro‐nano devices
as it can modify the interior of transparent optical materials in a spatially selective manner …

The interaction of intense femtosecond laser pulses with transparent materials is a topic that
has caused great interest of scientists over the past two decades. It will continue to be a …

Securely storing large amounts of information over relatively short timescales of 100 years,
comparable to the span of the human memory, is a challenging problem. Conventional …

Direct-write femtosecond laser nanostructuring of 300 nanometer thick a-Si: H films results in
space-variant functional metasurfaces with form birefringence of up to ne-no=–0.5 …

Skylight polarization is used for navigation by some birds and insects. Skylight polarization
also has potential for human navigation applications. Its advantages include relative …

Polarimetric cameras based on micropolarizer grids make it possible to design division of
focal plane (DoFP) polarimeters. However, the polarimetric estimation precision reached by …

Massively parallel femtosecond laser processing with more than 1000 beams was
demonstrated. Parallel beams were generated by a computer-generated hologram (CGH) …

Stable information of a sky light polarization pattern can be used for navigation with various
advantages such as better performance of anti-interference, no “error cumulative effect,” and …

Estimating the full Stokes vector with a linear division of focal plane (DoFP) camera and a
retarder requires at least two image acquisitions with different retarder settings. We …

Line-shaped femtosecond pulses are well-suited to large-area machining with high
throughput in laser cutting, peeling, and grooving of materials. First, we demonstrated the …
