We propose a method for adaptive waveguide bends using homogeneous, nonmagnetic, and isotropic materials, which simplifies the parameters of the bends to the utmost extent. The proposed bend has an adaptive and compac...

Ultrabroadband mid-IR continuum pulses can be detected on a single-shot basis using chirped-pulse upconversion. Converting the mid-IR pulse to the visible reduces the fractional bandwidth and enables use of a silicon ...
