Rofea 'modulator kubogama yabugenewe yabugenewe kubushakashatsi bwa Mach- Zehnder kugirango barebe imikorere ihamye mubikorwa bitandukanye. Ukurikije uburyo bwuzuye bwuzuye bwo gutunganya ibimenyetso, umugenzuzi arashobora gutanga ultra ihamye imikorere.
Umugenzuzi atera inshuro nke, amplitude make yerekana ibimenyetso hamwe na bias voltage muri modulator. Ikomeza gusoma ibisohoka muri modulator ikanagena imiterere ya bias voltage hamwe nikosa rifitanye isano. Umuvuduko mushya wo kubogama uzakoreshwa nyuma yijambo ukurikije ibipimo byabanje. Muri ubu buryo, modulator yemerewe gukora munsi ya bias ikwiye.
