Parallel Recording of Single Quantum Dot Optical Emission Using Multicore Fibers
Single Indium Arsenide Quantum Dot emission spectra have been recorded using a four-core, crosstalk-free, multicore fiber placed at the collection arm of a confocal microscope. We developed two different measurement set-ups depending on the relative configuration of the excitation and collection spots. In the single-matched mode, the emission from the excited area is collected by a single core in the multicore fiber, whereas the three remaining cores capture the emission from neighboring, non-excited areas. This procedure allows for the recording of the Quantum Dot emission from carrier diffusion between sample positions separated by more than 6 μm. In the multiple-matched mode, the ex…
1 Tb/s·km WDM transmission over multimode fibre link
We demonstrate 1 Tb/smiddotkm WDM error-free transmission (highest reported value to our knowledge) over a MMF link by a combination of low-linewidth lasers and central launch.
