3. Product overview Description Intended for free space optical communication, the TILBA-R is TILBA-R is a Multi-Plane Light-Conversion (MPLC) based an optical device designed to improve the reliability of the optical spatial demultiplexer that decomposes a beam wave-front link at reception in the presence of atmospheric turbulence or profile into a limited number of spatial modes. -

Also, depending on the material used, you will be able to measure Step 4: Align the beam. Use the circulator on the fundamental either the crosstalk sum in real-time or only the maximum power. channel. The objective is to send light and to measure the Measuring the crosstalk helps, but an accurate alignment can power reflected by the mirror and demultiplexed in the same be done without it. -

5. Crosstalk and coupling efficiency calculation Data measured: • Input power, given by an array Pin(i) corresponding to the input power on channel i • Output power, given by a matrix Pi-j corresponding to the output power on channel j when the light is on input channel i Calculation of coupling efficiency Method... -
