A good and efficient control of the focus point of a laser beam is essential in many fields such as laser processing and wielding, and confocal microscopy. The most common way of changing the focus position of a beam is to use lenses, usually in the form of a telescope. However, inertia imposes a limit to the frequency at which one can modulate the position of a mechanical element. Other techniques,...
Multi-Plane Light Conversion (MPLC) enables novel beam shaping devices, and in particular highly mode-selective spatial mode multiplexers. MPLC-based multiplexers can combine up to 10 spatial modes with cross-talk of −26dB and insertion loss below 4dB. These multiplexers are versatile and can be used in many applications, including long haul mode division multiplexing, short reach mode group division...
We report on a 6-mode spatial multiplexer based on multi-plane light conversion with 4.6dB insertion loss and −23dB mode-to-mode crosstalk, designed for few-mode fiber transmission systems that do not rely on complex electronic post-processing.
We present a spatial 6-mode multiplexer with low loss and high mode selectivity. We demonstrate 100Gbit/s error-free transmission over 20km for 6 modes and over 40km bi-directional transmission with 3 modes in each direction.
