Ultra High Precision MZM modulator Bias Igenzura Automatic Bias Controller

Ibisobanuro bigufi:

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.

Umubare ntarengwa wa DC

Muri ubu bushakashatsi, nta kimenyetso cya RF cyakoreshejwe kuri sisitemu.Ibipimo bya DC byuzuye byapimwe.
1. Igishushanyo cya 5 cyerekana imbaraga za optique zo gusohora modulator, mugihe modulator igenzurwa kuri Peak point.Irerekana 3.71dBm mu gishushanyo.
2. Igishushanyo cya 6 cyerekana imbaraga za optique zo gusohora modulator, mugihe modulator igenzurwa kuri Null point.Irerekana -46,73dBm mu gishushanyo.Mubigeragezo nyabyo, agaciro karatandukanye -47dBm;na -46.73 nigiciro gihamye.
3. Kubwibyo, igipimo gihamye cyo kuzimya DC cyapimwe ni 50.4dB.

Ibisabwa ku kigereranyo cyo kuzimangana

1. Modulator ya sisitemu igomba kuba ifite igipimo kinini cyo kuzimira.Ibiranga sisitemu modulator ihitamo igipimo ntarengwa cyo kuzimangana gishobora kugerwaho.
2. Polarisiyasi yumucyo winjiza urumuri igomba kwitabwaho.Abayobora bumva polarisiyasi.Gukwirakwiza neza birashobora kunoza igipimo cyo kuzimangana hejuru ya 10dB.Mubigeragezo bya laboratoire, mubisanzwe umugenzuzi wa polarisiyasi arakenewe.
3. Abashinzwe kubogama neza.Mu igeragezwa ryacu rya DC kuzimangana, 50.4dB yo kuzimangana byagezweho.Mugihe datasheet ya modulator ikora urutonde 40dB gusa.Impamvu yiri terambere nuko modulator zimwe zigenda vuba cyane.Rofea R-BC-BURUNDU abayobora kubogama bavugurura bias voltage buri segonda 1 kugirango barebe igisubizo cyihuse.
