We study and demonstrate angle-cleaved fusion splicing between single mode fiber (SMF) and nested anti-resonant node-less fiber (NANF). First, we analyze the trade-off between the connection loss a…
We report parametric gain by utilizing χ(2) non-linearities in a semiconductor Bragg Reflection Waveguide (BRW) waveguide chip. Under the two-mode degenerate type II phase matching, it can be show…
End-to-end trained convolutional neural networks have led to a breakthrough in optical flow estimation. The most recent advances focus on improving the optical flow estimation by improving the arch…
A new device concept - the reflective spiral phase converter - is presented. The converter can be used for generation of ultrashort optical vortices and takes advantage of spiral phase plate to imp…
This paper provides a discussion and evaluation of presolving methods for mixed-integer semidefinite programs. We generalize methods from the mixed-integer linear case and introduce new methods tha…
