Zvikumbiro zvitsva zveElectro-Optic modulator yechikamu
Modulator yeLiNbO3Phase modulator chinhu chakakosha chinogona kudzora shanduko yechikamu chemafungu echiedza, uye chinoita basa guru mukutaurirana kwemaziso kwemazuva ano uye kunzwa. Munguva pfupi yapfuura, mhando itsva yemodulator yechikamuYakakwezva kutariswa kwevaongorori nemainjiniya, iyo inoshanda nemafungu matatu e780nm, 850nm uye 1064nm, ine bandwidths yekushandura inosvika 300MHz, 10GHz, 20GHz uye 40GHz.
Chinhu chinonyanya kukosha cheiyi phase modulator i high modulation bandwidth uye low insertion loss. Insertion loss zvinoreva kudzikira kwesimba kana simba re optical signal mushure mekupfuura nepakati pe modulator. Insertion loss yeiyi phase modulator yakaderera zvikuru, izvo zvinoita kuti chiratidzo chirambe chakasimba, kuitira kuti chiratidzo chigone kuchengetedza simba rakawanda mushure me modulation.
Pamusoro pezvo, phase modulator ine hunhu hwe low half-wave voltage. Half-wave voltage ndiyo voltage inofanirwa kuiswa kune modulator kuti ichinje phase yechiedza nemadhigirii 180. Low half-wave voltage zvinoreva kuti voltage yakaderera chete ndiyo inodiwa kuti pave neshanduko huru mu optical phase, izvo zvinoderedza zvakanyanya kushandiswa kwesimba remuchina.
Panyaya dzekushandisa, iyi phase modulator itsva inogona kushandiswa zvakanyanya mu optical fiber sensing, optical fiber communication, phase delay (shifter), uye quantum communication. Mu optical fiber sensing, phase modulator inogona kuvandudza sensitivity uye resolution ye sensor. Mu optical fiber communication, inogona kuvandudza communication speed uye data transmission efficiency. Mu phase delay (shifter), inogona kunyatso dzora direction yekupararira kwechiedza; Mu quantum communication, inogona kushandiswa kudzora uye kugadzirisa quantum states.
Zvose zviri zviviri, phase modulator itsva inotipa nzira dzinoshanda uye dzakarurama dzekudzora optical, izvo zvichaunza shanduko huru muminda yakawanda. Tinotarisira kuti tekinoroji iyi ichavandudzwa uye kugadziriswa mune ramangwana, ichitiratidza zvimwe zvakavanzika zve optical.
