Ule ụzọ maka arụmọrụ nkeelectrooptic modulator

1. Ọkara-ebili voltaji ule nzọụkwụ makaeletrọ-optic ike modulator

Na-ewere voltaji ọkara ebili mmiri na ọdụ RF dịka ọmụmaatụ, isi iyi mgbama, ngwaọrụ a na-anwale na oscilloscope jikọtara site na ngwaọrụ ụzọ atọ. Mgbe ị na-anwale voltaji ọkara ebili mmiri na ọdụ Bias, jikọọ ya dịka ahịrị nwere ntụpọ.

b. Gbanwuo isi iyi ọkụ na isi mgbaama, ma tinye mgbama ebili mmiri sawtooth (ugo nnwale a na-ahụkarị bụ 1KHz) na ngwaọrụ a na-anwale. Mgbama ebili mmiri sawtooth Vpp kwesịrị ịdị ukwuu karịa okpukpu abụọ nke voltaji ọkara.

c. Gbanwuo oscilloscope;

d. Mgbama mmepụta nke ihe nchọta bụ mgbama cosine. Dekọọ ụkpụrụ voltaji ebili mmiri sawtooth V1 na V2 dabara na ọnụ ọnụ ugwu na ọwa mmiri nke mgbama a. e. Gbakọọ voltaji ọkara ebili mmiri dịka Formula (3).

2. Nyochaa nzọụkwụ maka ọkara-efegharị voltaji nkeeletrọ-optic akụkụ modulator

Mgbe ejikọta usoro ule ahụ, ọdịiche ụzọ anya anya dị n'etiti ogwe aka abụọ nke na-emepụta ihe nhazi interferometer anya ga-adị n'ime ogologo oge. A na-ejikọta isi iyi mgbaàmà na ọdụ RF nke ngwaọrụ a na-anwale yana ọwa 1 nke oscilloscope site na ngwaọrụ ụzọ atọ. Mgbe ejikọta usoro ule ahụ, ọdịiche ụzọ anya anya dị n'etiti ogwe aka abụọ nke na-emepụta ihe nhazi interferometer anya ga-adị n'ime ogologo oge. A na-ejikọta isi iyi mgbaàmà na ọdụ RF nke ngwaọrụ a na-anwale yana ọwa 1 nke oscilloscope site na ngwaọrụ ụzọ atọ, na-edozi ọdụ ụgbọ mmiri nke oscilloscope ka ọ bụrụ ọnọdụ dị elu.

b. Gbanwuo laser na isi iyi mgbama, ma tinye mgbama ebili mmiri sawtooth nke otu ugboro (ụkpụrụ a na-ahụkarị 50KHz) na ngwaọrụ a na-anwale. Mgbama mmepụta nke ihe nchọta bụ mgbama cosine. Vpp nke mgbama ebili mmiri sawtooth kwesịrị ịdị ukwuu karịa okpukpu abụọ nke ọkara ebili mmiri, mana ọ gaghị agafe oke ntinye voltaji nke modulator akọwapụtara, nke mere na nsonaazụ cosine nke ihe nchọta na-egosi opekata mpe otu okirikiri zuru oke.

c. Dekọọ ụkpụrụ voltaji ebili mmiri sawtooth V1 na V2 dabara na ọnụ ọnụ ọnụ na mmiri mmiri nke mgbama cosine;

d. Gbakọọ voltaji ọkara ebili mmiri dịka Formula (3).

3. Ntinye ntinye nke igwe eletrọ-optic modulators

Nwalee nzọụkwụ

Mgbe ijikọsịrị isi iyi ọkụ na polarizer, gbanye isi ọkụ wee nwalee ike ntinye anya Pi nke ngwaọrụ n'okpuru ule na mita ike anya.

b. Jikọọ ngwaọrụ dị n'okpuru ule na sistemu nnwale, wee jikọta njedebe mmepụta nke ọkụ ọkụ a na-ahazi na ntụtụ 1 (GND) na 2 (Bias) nkemodulator(maka ụfọdụ batches nke modulators, pin 1 nke modulator kwesịkwara jikọọ na ụlọ).

c. Gbanwee voltaji mmepụta nke ọkụ a na-achịkwa ma nwalee ọgụgụ kachasị elu nke mita ike anya dị ka Pout.

d. Ọ bụrụ na ngwaọrụ a na-anwale bụ modulator usoro, ọ dịghị mkpa ịgbakwunye ọkụ eletrik na-eme ka ike dị ike. Enwere ike gụọ Pout ozugbo site na mita ike anya.

e. Gbakọọ mfu ntinye dịka usoro (1) siri dị.

a. Ntinye anya nke modulator electro-optic agaghị agafe uru nhazi na akụkọ nyocha; ọzọ, naEO modulatorga-emebi emebi.

b. Ntinye RF nke modulator electro-optic agaghị agafe uru ngbanwe dị na mpempe ule; ma ọ bụghị ya, EO modulator ga-emebi.

c. Mgbe ị na-edozi interferometer, enwere ihe achọrọ dị elu maka gburugburu ojiji. Ịma jijiji gburugburu ebe obibi na ịgbagharị eriri anya nwere ike imetụta nsonaazụ ule ahụ.
