The field of 3D micro‐optics is rapidly expanding, and essential advances in femtosecond
laser direct‐write 3D multi‐photon lithography (MPL, also known as two‐photon or multi …

Abstract Two‐Photon Lithography, thanks to its very high sub‐diffraction resolution, has
become the lithographic technique par excellence in applications requiring small feature …

With the advent of femtosecond lasers in the early 1990s, ultrafast laser processing has
proven to be an imperative tool for micro/nano machining. Two-photon lithography (TPL) is …

Current lens systems are restricted in size, shape and dimensions by limitations of
manufacturing. Multi-lens elements with non-spherical shapes are required for high optical …

The flat endface of an optical fiber tip is an emerging light-coupled microscopic platform that
combines fiber optics with planar micro-and nanotechnologies. Since different materials and …

Micro-optics are widely used in numerous applications, such as beam shaping, collimation,
focusing and imaging. We use femtosecond 3D printing to manufacture free-form micro …
