Mmalite dị mkpirikpi nke teknụzụ laser modulator

Okwu mmeghe dị mkpirikpi nke laserihe nhaziteknụzụ
Laser bụ ebili eletriki ugboro ugboro, n'ihi na ọ na-ejikọta nke ọma, dịka ebili eletriki ọdịnala (dịka eji eme ihe na redio na telivishọn), dị ka ebili eletriki ebu iji zipu ozi. A na-akpọ usoro nke itinye ozi na laser modulation, a na-akpọkwa ngwaọrụ nke na-eme usoro a modulator. N'ime usoro a, laser na-arụ ọrụ dị ka onye na-ebu ya, ebe a na-akpọ akara ugboro ugboro dị ala nke na-ebunye ozi ahụ akara modulated.
A na-ekewakarị mgbanwe laser n'ime modulation na mpụga ụzọ abụọ. Mgbanwe ime: na-ezo aka na mgbanwe n'usoro nke mgbanwe laser, ya bụ, site na ịgbanwe mgbaàmà ahụ iji gbanwee paramita oscillation nke laser, si otú a na-emetụta njirimara mmepụta nke laser. E nwere ụzọ abụọ nke mgbanwe ime: 1. Na-achịkwa ọkụ eletrik nke laser ozugbo iji gbanwee ike nke mmepụta laser. Site na iji mgbaàmà ahụ iji chịkwaa ọkụ eletrik laser, ike mmepụta laser nwere ike ịchịkwa site na mgbaàmà. 2. A na-etinye ihe nhazi na resonator, a na-achịkwa njirimara anụ ahụ nke ihe nhazi ndị a site na mgbaàmà, wee gbanwee paramita nke resonator iji nweta mgbanwe nke mmepụta laser. Uru nke mgbanwe ime bụ na arụmọrụ mgbanwe dị elu, mana ọghọm ya bụ na n'ihi na modulator dị n'ime oghere ahụ, ọ ga-eme ka mfu dị n'ime oghere ahụ dịkwuo elu, belata ike mmepụta, a ga-ejedebekwa bandwit nke modulator site na pasband nke resonator. Mgbanwe mpụga: pụtara na mgbe e guzobere laser ahụ, a na-etinye modulator ahụ n'okporo ụzọ anya dị n'èzí laser ahụ, a na-agbanwekwa njirimara anụ ahụ nke modulator ahụ site na iji akara modulated, mgbe laser gafere site na modulator ahụ, a ga-agbanwe paramita ụfọdụ nke ebili mmiri ọkụ ahụ. Uru nke mgbanwe mpụga bụ na ike mmepụta nke laser anaghị emetụta na bandwidth nke njikwa anaghị ejedebe site na pasband nke resonator. Ihe na-adịghị mma bụ obere arụmọrụ mgbanwe.
Enwere ike kewaa mgbanwe laser n'ime mgbanwe olu, mgbanwe ugboro ugboro, mgbanwe usoro na mgbanwe ike dịka njirimara mgbanwe olu ya si dị. 1, mgbanwe olu: mgbanwe olu bụ mgbanwe olu nke oke nke onye na-ebu ya na-agbanwe na iwu nke mgbaàmà agbanwere agbanwe. 2, mgbanwe ugboro ugboro: ịgbanwe akara ahụ iji gbanwee ugboro ugboro nke mgbanwe olu laser. 3, mgbanwe usoro: ịgbanwe akara ahụ iji gbanwee oge nke laser oscillation.

Ihe na-eme ka ike eletriki rụọ ọrụ
Ụkpụrụ nke mgbanwe ike electro-optic bụ ịghọta mgbanwe ike dịka ụkpụrụ nnyonye anya nke ìhè polarized si dị site na iji mmetụta electro-optic nke kristal. Mmetụta electro-optic nke kristal na-ezo aka na ihe na-eme ka index refractive nke kristal na-agbanwe n'okpuru ọrụ nke ubi eletrik mpụga, na-ebute ọdịiche nke usoro n'etiti ìhè na-agafe na kristal na ntụziaka polarization dị iche iche, nke mere na ọnọdụ polarization nke ìhè na-agbanwe.

Modulator nke oge elektrọnik
Ụkpụrụ nhazi usoro electro-optical: usoro nhazi usoro mgbanwe na-agbanwe akụkụ nke oscillation laser site na iwu nke nhazi usoro.

Na mgbakwunye na nhazi ike electro-optic na nhazi usoro electro-optic dị n'elu, enwere ọtụtụ ụdị modulators laser, dị ka transverse electro-optic modulator, electro-optic traveling wave modulator, Kerr electro-optic modulator, acousto-optic modulator, magnetooptic modulator, interference modulator na spatial light modulator.
