Umugenzuzi w’Uburyo bwo Guhuza Ibiranga bya Ultra Compact DP-IQ Modulator
Ikiranga
•Itanga icyarimwe voltage esheshatu za automatic bias kuri modulators za Dual Polarization IQ
•Imiterere y'impinduka idashingiye ku buryo busanzwe:
SSB, QPSK, QAM, OFDM byemejwe.
• Komeka hanyuma ukinishe:
Nta gupima intoki bikenewe. Byose byikora ku buryo bwikora.
•I, Q arms: controll kuri Peak na Null modes Igipimo cyo kuzimira kinini:50dB max1
•Uruhande rwa P: kugenzura uburyo bwa Q+ na Q- Ubuziranenge: ± 2◦
•Uburebure buke: 40mm(W) × 29mm(D) × 8mm(H)
•Gutuza cyane: ishyirwa mu bikorwa ryuzuye rya digitale Byoroshye gukoresha:
•Gukoresha intoki ukoresheje mini jumper 2
Ibikorwa bya OEM byoroshye binyuze muri UART / IO
• Uburyo bubiri bwo gutanga voltages za bias: a. Kugenzura Bias Automatic b. Voltage ya bias igenwa n'umukoresha
Porogaramu
•LiNbO3 n'izindi modulators za DP-IQ
•Ihererekanyamakuru rihuza
1Igipimo cyo kurimbuka kinini gishingiye kandi ntigishobora kurenza 1 igipimo cyo kurimbuka ntarengwa cya modulator.
2Umurimo wa UART uboneka gusa kuri verisiyo imwe y'igikoresho cyo kugenzura.

1 MER yerekeza ku gipimo cy’irimbuka rya Modulator. Igipimo cy’irimbuka cyabonetse ubusanzwe ni igipimo cy’irimbuka rya modulator kivugwa mu rupapuro rw’amakuru rwa modulator.
2RekaVπ garagaza voltage ya bias kuri 180◦ naVP garagaza voltage nziza cyane ya bias kuri Quad points.
3Menya neza ko imbaraga z'urumuri zinjira zitavuga imbaraga z'urumuri ziri ku gice cyatoranijwe cya bias. Ni imbaraga ntarengwa z'urumuri modulator ishobora kohereza kuri controller iyo voltage ya bias iri hagati ya−Vπ kuri +Vπ .

1 Polar iterwa n'ikimenyetso cya RF cya sisitemu. Iyo nta kimenyetso cya RF kiri muri sisitemu, polar igomba kuba nziza. Iyo ikimenyetso cya RF gifite amplitude irenze urwego runaka, polar izahinduka kuva kuri nziza ijya kuri negative. Muri iki gihe, Null point na Peak point bizahindukana. Q+ point na Q- point bizahindukana. Polar switch ituma umukoresha ashobora guhindura

Ni byiza gukoresha photodiode igenzura mu igerageza rya laboratwari kubera impamvu ebyiri. Ubwa mbere, photodiode igenzura ifite ubwiza buhamye. Icya kabiri, biroroshye guhindura ubukana bw'urumuri rwinjiye. Niba ukoresha photodiode y'imbere ya modulator, nyamuneka menya neza ko umuvuduko w'urumuri rwa photodiode ujyanye neza n'imbaraga zinjiye.
