Low-light upconversion imaging at 1950nm using a PPLN waveguide

Low-light upconversion imaging at 1950nm using a PPLN waveguide
Low-light upconversion imaging at 1950nm using a PPLN waveguide
We report a low light infrared raster-scanning nonlinear imaging system that utilises a single-mode fiberized zinc-indiffused MgO:PPLN waveguide for upconversion via sum-frequency generation, permitting detection with an 850nm superconducting nanowire single-photon detector. The system operates with 1950nm illumination or pulsed 1571nm illumination, to generate upconverted images and time-of-flight upconverted images, respectively, at 870nm.

Abstract

We report a low light infrared raster-scanning nonlinear imaging system that utilises a single-mode fiberized zinc-indiffused MgO:PPLN waveguide for upconversion via sum-frequency generation, permitting detection with an 850nm superconducting nanowire single-photon detector. The system operates with 1950nm illumination or pulsed 1571nm illumination, to generate upconverted images and time-of-flight upconverted images, respectively, at 870nm.
