Yethula i-electro-optic phase modulator ye-half-wave voltage ephezulu kakhulu

Ubuciko obunembile bokulawula imisebe yokukhanya:I-modulator yesigaba se-electro-optic se-half-wave voltage ephansi kakhulu

Esikhathini esizayo, yonke intuthuko ekuxhumaneni kwe-optical izoqala ngokusungulwa kwezingxenye eziyinhloko. Ezweni lokuxhumana kwe-optical okusheshayo kanye nezinhlelo zokusebenza ze-photonics ezinembile, ukulawulwa okunembile kwesigaba samaza okukhanya bekulokhu kuyisihluthulelo sokucindezela imingcele yobuchwepheshe. Ukulungiswa okucashile kwesigaba kuhlobene nomthamo, isivinini kanye nokwethembeka kokudluliselwa kolwazi. Kulokhu, sethula i-electro-optic ye-voltage ye-half-wave ephansi kakhulu ye-Rofea.i-modulator yesigaba.

Akuyona nje intoi-modulator, kodwa umlingani onekhono kuwe ukuze ufeze “ubuciko obucophelelayo” ezinhlelweni ze-photonic. Lolu chungechunge lwemikhiqizo luthatha isici salo se-voltage esiphansi kakhulu se-half-wave njengenzuzo yalo eyinhloko, okusho ukuthi ungafinyelela ukusebenza kahle kwe-phase modulation ephezulu kakhulu nge-voltage ephansi yokushayela, okunciphisa kakhulu ukusetshenziswa kwamandla esistimu kanye nobunzima bokuklama kwesekethe yokushayela.

Okwamanje, i-voltage ye-half-wave ephansi kakhului-electro-optic phase modulatorihlanganisa ukulahlekelwa okuphansi kokufakwa, i-bandwidth ephezulu yokuguquguquka kanye nomkhawulo womonakalo omkhulu, iqinisekisa ukuthi isignali igcina ubuqotho obuhle kakhulu kanye nomthamo wokuphatha amandla ngesikhathi senqubo yokuguquguquka ephumelelayo. Kungakhathaliseki ukuthi isetshenziselwa ukuphathwa kwe-optical chirp ezinhlelweni zokuxhumana ezisheshayo ukuthuthukisa ikhwalithi yokudlulisa isignali; Isakwazi ukufeza ukushintsha kwesigaba okunembile kokuxhumana okuhlangene; Kungakhathaliseki ukuthi ingakhiqiza amabhande aseceleni amsulwa ezinhlelweni ze-ROF noma icindezele ngempumelelo imiphumela engeyona eqondile ekuxhumaneni kwe-analog, ingasingatha izimo ezahlukahlukene zohlelo lokusebenza ezifunwa kakhulu kalula. Isetshenziswa kakhulu emikhakheni yokulawula i-optical chirp ezinhlelweni zokuxhumana ze-optical ezisheshayo, ukushintsha kwesigaba ezinhlelweni zokuxhumana ezihlangene, ukukhiqizwa kwebhande eliseceleni ezinhlelweni ze-ROF, kanye nokunciphisa ukusabalala kwe-Brillouin okushukumisayo (SBS) ezinhlelweni zokuxhumana ze-analog optical fiber.
