Ukuthuthukiswa kanye Nezimakethe Zesimo se-Laser eguqukayo (Ingxenye Yesibili)

Ukusebenza komgomo weI-Laser ye-Tunble

Kunemigomo emithathu ecishe ibe yimikhawulo yokuthola i-laser wavelth tuning. Kakhuluama-lasers amathubaSebenzisa izinto zokusebenza ngemigqa ebanzi ye-fluorescent. Ama-resonators akha i-laser abe nokulahlekelwa okuphansi kakhulu ngaphezulu kobubanzi obuncane obukhulu kakhulu. Ngakho-ke, owokuqala ukushintsha i-wavengerth ye-laser ngokushintsha i-wavengength ehambelana nesifunda esiphansi sokulahleka kwe-resonator ngezinto ezithile (ezifana ne-grating). Okwesibili ukuguqula izinga lamandla wenguquko ye-laser ngokushintsha amapharamitha athile angaphandle (njengamandla kazibuthe, izinga lokushisa, njll.). Okwesithathu ukusetshenziswa kwemiphumela engahlukaniswanga ukufeza ukuguqulwa kanye nokuguqulwa kwe-wavengeth kanye nokuhleleka (bheka ama-nonlinear Optics, avuselelwa amaRama, imvamisa ye-Optical Frequency Okuphindaphindwe kabili, i-Optical Parametric Oscillation). Ama-lasers ajwayelekile emodi yokuqala yokuhlenga ama-lasers edayi, ama-chrysoberyl lasers, ama-lasers anemibala, ama-lasers asezingeni eliphakeme kakhulu wegesi kanye nama-lasesser amnandi.

I-Laser ye-Tuneble kusuka ngombono wobuchwepheshe bokuqaphelisisa ihlukaniswe kakhulu: Ubuchwepheshe bokulawula kwamanje, ubuchwepheshe bokulawula izinga lokushisa nobuchwepheshe bokulawula okwenziwe ngomshini.
Phakathi kwazo, ubuchwepheshe bokulawula nge-elekthronikhi ukufezekisa ukuguquguquka kwe-wavevethy ngokushintsha umjovo wamanje, nge-NS-Level tuning tuning technology ikakhulukazi i-SG-DBR (Supping DBR (Suppling DBR (I-AUxiling Grating Coupling Revalward Reclings). Ubuchwepheshe bokulawulwa kokushisa bushintsha i-wavexth ye-laser ngokushintsha inkomba ye-Laser active Region. Ubuchwepheshe bulula, kepha buhamba kancane, futhi bungashintshwa ngobubanzi bebhendi obuncane bokuphela okumbalwa. Okusemqoka kususelwa kubuchwepheshe bokulawula izinga lokushisaI-DFB laser(Impendulo esatshalaliswa) ne-DBR laser (isatshalaliswe i-Bragg Reflection). Ukulawulwa kwemishini kususelwa ikakhulu kuma-MEMS (ama-Micro-Electro-Mechanical System) Ukuqedela ukukhethwa kwe-wavelength, nge-bandwidth enkulu eguqukayo, amandla aphezulu okukhipha. Izinhlaka eziphambili ezisuselwa kubuchwepheshe bokulawula abasebenza ngemishini yi-DFB (Impendulo Esetshenzisiwe), ECL (I-Cavity Laser Laser) ne-Vcsel (Vertical Cavity Survity Surfaving Engittang Laser). Okulandelayo kuchazwa kulezi zinto zomgomo wama-lasers amathuba.

Isicelo sokuxhumana se-Optical

I-Laser ye-Tuneble iyithuluzi eliyisihluthulelo se-Optoelectronic esizukulwaneni esisha sohlelo olulodwa lwe-wavelength division oluningi kanye ne-Photon Exchange kunethiwekhi ye-Optical. Ukusetshenziswa kwayo kwandisa kakhulu umthamo, ukuguquguquka kanye nokukhubazeka kohlelo lokuhambisa i-fiber oplo
Izinkampani nezikhungo zokucwaninga emhlabeni wonke zithuthukisa ngenkuthalo ucwaningo kanye nokuthuthukiswa kwama-lasers amathuba, nenqubekela phambili entsha ihlala yenziwa kulo mkhakha. Ukusebenza kwama-lasers amathuba kuhlala kuthuthukiswa futhi izindleko zincishiswa njalo. Njengamanje, ama-lasers aguqukayo ahlukaniswe ngezigaba ezimbili: ama-leconductor ama-lasers ama-lasers nama-Iful I-fiber lasers.
I-Semiconductor LaserIngabe umthombo wokukhanya obalulekile ohlelweni lokuxhumana obonakalayo, onezimpawu zobukhulu obuncane, isisindo esikhanyayo, ukusebenza kahle kwamandla, ukulondolozwa kwamandla, njll., Futhi kulula ukufeza ukuhlanganiswa okukodwa kwe-chip optoelectronic namanye amadivaysi. Ingahlukaniswa ibe yimpendulo ye-APEMEBHA EBONAKALAYO EBONAKALAYO, isatshalaliswe i-Bragg Mirror Laser, i-Micromotor System Vertical Survity Survity ekhipha i-laser ne-cavity semicinductor laser.
Ukuthuthukiswa kwe-Internet ye-fiber laser njengokuthola okuphakathi kanye nokuthuthukiswa kwe-semiconductor laser diode njengomthombo wamaphampu kukhuthaze kakhulu ukuthuthukiswa kwama-lasers e-fiber lasers. I-laser yethuba isuselwa ku-bandwidth ye-80nm ye-fiber ethambekele, bese into yokuhlunga ingezwe ku-loop ukulawula i-wavelth ye-lasheth.
Ukuthuthukiswa kwe-semiconductor laser kukhuthele kakhulu emhlabeni, futhi intuthuko nayo iyashesha kakhulu. Njengama-ama-Liture Lasers afinyelela kancane kancane kancane ama-wavelength lasers ngokuya ngezindleko kanye nokusebenza, azosetshenziswa nakanjani ku-Systems Systems futhi adlale indima ebalulekile kumanethiwekhi wesikhathi esizayo.

Ithemba Lokuthuthuka
Kunezinhlobo eziningi zama-lasers amathuba, ezivame ukwakhiwa ngokungenisa ezinye izindlela ze-wavengeng ngesisekelo sama-laserser ahlukahlukene we-wavelength, kanti ezinye izinto zinikezwe emakethe emhlabeni jikelele. Ngaphezu kokuthuthukiswa kwama-lasers aqhubekayo ama-lasers aqhubekayo, ama-lasers amathuba aneminye imisebenzi ehlanganisiwe nawo kubikwe, njenge-laser amuncy modulator, futhi i-laser ihlanganiswe ne-amplifier ye-statical brang kanye ne-semicenductor yokuvuma.
Ngoba i-wavengethfung i-laser isetshenziswa kabanzi, i-laser eguqukayo yezakhiwo ezahlukahlukene ingafakwa ezinhlelweni ezahlukahlukene, futhi ngamunye unezinzuzo nobubi. I-laser yangaphandle ye-cavity semicenductor ingasetshenziswa njengomthombo wokukhanya okhanyayo we-ebanzi ekukhetheni amathuluzi wokuhlola ngokunemba ngenxa yamandla ayo aphezulu okuphuma kanye ne-wavelength eqhubekayo. Ngokombono wokuhlanganiswa kwe-Photon futhi uhlangabezana nekusasa le-All-Optical Network, i-Fratical PBR yesampula, ama-DBR aphezulu we-dbr kanye nama-ampleble ama-lasers ahlanganiswe nama-modulators nama-amplifiers kungenzeka athembisa imithombo yokukhanya ekhanyayo ye-Z.
I-langer ye-grating tusheble laser nge-cavity yangaphandle nayo iyindlela ethembisayo yomthombo wokukhanya, onesihlaka esilula, ububanzi be-fiber obuncane kanye nokuhlangana okulula kwe-fiber nokuhlangane okulula. Uma i-modulator ye-EA ingahlanganiswa e-cavity, ingasetshenziswa futhi njenge-speed isivinini esiphezulu se-optical soliton soliton. Ngaphezu kwalokho, ama-Life lasers ama-fiber asuselwa kuma-lasers e-fiber athuthuke kakhulu eminyakeni yamuva. Ingalindelwa ukuthi ukusebenza kwama-lasers amahle emithonjeni ekhanyayo yokukhanya okulula kuzothuthukiswa, futhi isabelo semakethe sizokhuphuka kancane kancane, ngamathemba wesicelo aqhakazile kakhulu.
