TL;DR: In this paper, a simple, rapid and inexpensive nanolithography technique is demonstrated that exploits nonlinear feedback mechanisms to tightly regulate the formation of nanostructures induced by femtosecond laser pulses.

TL;DR: In this paper, a tensile-strained Ge p-i-n photodetector with an extended detection spectrum of 650-1605 nm and a 3 dB bandwidth of 8.5 GHz measured at λ=1040nm is presented.

TL;DR: An all-fiber-integrated laser based on off-the-shelf components producing square-shaped, 1 ns-long pulses at 1.03 μm wavelength with 3.1 MHz repetition rate and 83 W of average power is demonstrated.

TL;DR: Laser-based fabrication of complex 3D structures deep inside silicon using 1-µm-sized dots and rod-like structures of adjustable length as basic building blocks are demonstrated, enabling the creation of numerous photonic devices.

TL;DR: F Fresnel holograms that form on-axis with full depth control without any crosstalk are demonstrated, producing large-volume, high-density, dynamic 3D projections with 1,000 image planes simultaneously, improving the state of the art for the number of simultaneously created planes by two orders of magnitude.
