Umgomo wokulungisa we-Tunable semiconductor laser (i-Tunable laser)

Isimiso sokulungisaI-laser ye-semiconductor elungisekayo(I-laser elungisekayo)

I-laser ye-semiconductor elungisekayo uhlobo lwe-laser olungashintsha njalo ubude be-wavelength yokukhishwa kwe-laser ebangeni elithile. I-laser ye-semiconductor elungisekayo isebenzisa ukulungiswa kokushisa, ukulungiswa kukagesi kanye nokulungiswa kwemishini ukulungisa ubude be-cavity, i-grating reflection spectrum, isigaba kanye nezinye izinto eziguquguqukayo ukuze kufezwe ukulungiswa kwe-wavelength. Lolu hlobo lwe-laser lunezinhlobo eziningi zezicelo ekuxhumaneni kwe-optical, i-spectroscopy, i-sensing, i-medical kanye neminye imikhakha. Isibalo 1 sibonisa ukwakheka okuyisisekelo kwe-ai-laser elungisekayo, kufaka phakathi iyunithi yokuzuza ukukhanya, umgodi we-FP owakhiwe yizibuko zangaphambili nezangemuva, kanye neyunithi yesihlungi sokukhetha imodi yokukhanya. Okokugcina, ngokulungisa ubude bomgodi wokubonakalisa, isihlungi semodi yokukhanya singafinyelela umphumela wokukhetha ubude be-wavelength.

Indlela yokulungisa kanye nokutholakala kwayo

Umgomo wokulungisa we-tunableama-laser e-semiconductorikakhulukazi kuncike ekushintsheni amapharamitha angokwenyama e-laser resonator ukuze kufezwe izinguquko eziqhubekayo noma ezihlukile kubude be-laser obuphumayo. La mapharamitha afaka, kodwa awagcini lapho, inkomba yokubuyisa, ubude be-cavity, kanye nokukhethwa kwemodi. Okulandelayo kuchaza izindlela eziningana ezivamile zokulungisa kanye nezimiso zazo:

1. Ukucushwa komjovo wenkampani yokuthwala

Ukulungiswa komjovo wenkampani yokuthwala ukushintsha inkomba yokubuyisa yento ngokushintsha umsinga ofakwe endaweni esebenzayo ye-laser ye-semiconductor, ukuze kufezwe ukulungiswa komsinga. Lapho umsinga ukhula, ukuhlushwa komthwali esifundeni esisebenzayo kuyanda, okuholela ekushintsheni kwenkomba yokubuyisa, okubuye kuthinte ubude bomsinga we-laser.

2. Ukulungiswa kwe-thermal Ukulungiswa kwe-thermal ukushintsha inkomba yokubuyisa kanye nobude besikhala sento ngokushintsha izinga lokushisa lokusebenza kwe-laser, ukuze kufezwe ukulungiswa kwe-wavelength. Izinguquko ekushiseni zithinta inkomba yokubuyisa kanye nosayizi obonakalayo wento.

3. Ukulungisa ngomshini Ukulungisa ngomshini ukufeza ukulungiswa kwe-wavelength ngokushintsha indawo noma i-engela yezinto zangaphandle ze-optical ze-laser. Izindlela ezivamile zokulungisa ngomshini zifaka phakathi ukushintsha i-engela ye-diffraction grating kanye nokuhambisa indawo yesibuko.

4 Ukulungiswa kwe-Electro-optical Ukulungiswa kwe-electro-optical kufezwa ngokusebenzisa insimu kagesi ezintweni ze-semiconductor ukushintsha inkomba yokukhanya kwezinto, ngaleyo ndlela kufezwe ukulungiswa kwe-wavelength. Le ndlela ivame ukusetshenziswa ku-ama-modulators e-electro-optical (I-EOM) kanye nama-laser alungiswe ngogesi.

Ngamafuphi, isimiso sokulungisa se-laser ye-semiconductor elungisekayo ngokuyinhloko siqaphela ukulungiswa kwe-wavelength ngokushintsha amapharamitha angokwenyama e-resonator. Lawa mapharamitha afaka i-refractive index, ubude be-cavity, kanye nokukhethwa kwemodi. Izindlela ezithile zokulungisa zifaka phakathi ukulungiswa kwe-carrier injection, ukulungiswa kwe-thermal, ukulungiswa kwe-mechanical kanye nokulungiswa kwe-electro-optical. Indlela ngayinye inendlela yayo ethile yomzimba kanye nokutholwa kwezibalo, futhi ukukhethwa kwendlela efanele yokulungisa kudinga ukucatshangelwa ngokuya ngezidingo ezithile zohlelo lokusebenza, njengobubanzi bokulungisa, isivinini sokulungisa, isixazululo kanye nokuzinza.
