Lub koom haum Ferdinand-Braun-Institut, Leibnis-InstitutfürHöchstfrequenztechnik (FBH) yuav koom nrog hauv xov tooj cua
Lub rooj sib tham plaub-hnub coj los ua ke cov kws tshaj lij los ntawm kev yees duab yees duab, kho qhov muag, microsystemstechnology, thiabquantumtechnology.Cov kws tshawb fawb los ntawm Ferdinand-Braun-Institut yuav nthuav qhia lublatestresultsonhigh-powerdiodelasers, UVLEDs suav nrog cov kev cuam tshuam txog kev tiv thaiv kev tiv thaiv kab mob.
