Ntinye nkenke nke lasermodulatorteknụzụ
Laser bụ ebili mmiri eletrọnịkụlụ dị elu, n'ihi ịdị mma ya, dị ka ebili mmiri elektrọnik ọdịnala (dị ka eji na redio na telivishọn), dị ka ebili mmiri na-ebufe ozi. Usoro ntinye ozi na laser ka a na-akpọ modulation, na ngwaọrụ na-arụ usoro a ka a na-akpọ modulator. N'ime usoro a, laser na-arụ ọrụ dị ka onye na-ebu ya, ebe mgbama dị ala nke na-ebufe ozi a na-akpọ mgbama modulated.
A na-ekewakarị modul laser n'ime modulation na mpụta modulation ụzọ abụọ. Mgbanwe nke ime: na-ezo aka na mgbanwe mgbanwe na usoro nke laser oscillation, ya bụ, site n'ịgbanwe mgbaàmà iji gbanwee paramita oscillation nke laser, si otú ahụ na-emetụta njirimara mmepụta nke laser. Enwere ụzọ abụọ nke ime mgbanwe n'ime: 1. Jikwaa ngwa ngwa mgbapụta ọkụ nke laser iji dozie ike nke mmepụta laser. Site n'iji mgbaama na-achịkwa ọkụ ọkụ laser, ike mmepụta laser nwere ike ijikwa akara ngosi. 2. A na-etinye ihe ndị na-agbanwe agbanwe na resonator, na njirimara anụ ahụ nke ihe ndị a na-eme ka a na-achịkwa ihe mgbaàmà ahụ, mgbe ahụ, a na-agbanwe paramita nke resonator iji nweta mgbanwe nke mmepụta laser. Uru nke ime mgbanwe n'ime ime bụ na arụmọrụ modulation dị elu, ma ọ dịghị mma bụ na n'ihi na modulator dị n'ime oghere ahụ, ọ ga-eme ka ọnwụ dị na oghere ahụ dịkwuo elu, belata mmepụta ike, na bandwit nke modulator ga-adịkwa. ejedebere site na passband nke resonator. Mgbanwe nke mpụga: pụtara na mgbe emechara laser, a na-edobe modulator n'okporo ụzọ anya n'èzí laser, a na-agbanwe njirimara anụ ahụ nke modulator site na mgbama a gbanwere, na mgbe laser gafere modulator, otu oke. a ga-agbanwe nke ebili mmiri ọkụ. Uru nke modulation mpụga bụ na ike mmepụta nke laser adịghị emetụta na bandwit nke njikwa anaghị ejedebe site na passband nke resonator. Ọdịmma ya bụ arụmọrụ modulation dị ala.
Enwere ike kewaa modulation laser n'ime njupụta modulation, mgbanwe ugboro ugboro, modulation nke oge na ike ike dị ka njirimara modulation ya siri dị. 1, amplitude modulation: amplitude modulation bụ oscillation na njupụta nke ebu na-agbanwe na iwu nke mgbama modulated. 2, mmụgharị ugboro ugboro: iji megharịa mgbaama iji gbanwee ugboro ole oscillation laser. 3, modul modul nke oge: iji megharịa mgbaama iji gbanwee akụkụ nke laser oscillation laser.

Electro-optical ike modulator
Ụkpụrụ nke ngbanwe nke ike electro-optic bụ ịghọta mgbanwe mgbanwe ike dị ka ụkpụrụ nnyonye anya nke ìhè polarized si dị site na iji mmetụta electro-optic nke crystal. Mmetụta electro-optical nke kristal na-ezo aka n'ihe na-eme na ntụgharị ntụgharị nke kristal na-agbanwe n'okpuru ọrụ nke eletrik eletrik dị n'èzí, na-eme ka ọdịiche nke oge dị n'etiti ìhè na-agafe kristal n'ụzọ dị iche iche polarization, nke mere na polarization. ọnọdụ nke ìhè na-agbanwe.

Electro-optic frasi modulator
Ụkpụrụ modulation nke electro-optical: A na-agbanwe akụkụ akụkụ nke oscillation laser site n'iwu nke na-emegharị mgbaama.

Na mgbakwunye na ngbanwe nke ike electrooptic dị n'elu na mgbanwe usoro electro-optic, enwere ọtụtụ ụdị modulators laser, dị ka transverse electro-optic modulator, electrooptic traveling wave modulator, Kerr electro-optic modulator, acousto-optic modulator. , magnetooptic modulator, nnyonye anya modulator na oghere ọkụ modulator.
