Umgomo wokushuna we-Tunable semiconductor laser (Tunable laser)

Umgomo wokushuna weI-laser ye-semiconductor etholakalayo(Tunable laser)

I-laser semiconductor tunable iwuhlobo lwe-laser olungashintsha ngokuqhubekayo ubude begagasi be-laser okukhiphayo ebangeni elithile. I-laser ye-semiconductor ye-tunable yamukela ukushuna okushisayo, ukulungisa ugesi kanye nokushuna kwemishini ukuze kulungiswe ubude be-cavity, i-grating reflection spectrum, isigaba nokunye okuguquguqukayo ukuze kuzuzwe ukushunwa kwe-wavelength. Lolu hlobo lwe-laser lunohlu olubanzi lwezinhlelo zokusebenza zokuxhumana nge-optical, spectroscopy, sensing, medical and other fields. Umfanekiso 1 ubonisa ukwakheka okuyisisekelo kwe-ai-laser ephathekayo, okuhlanganisa iyunithi yokuzuza ukukhanya, imbobo ye-FP eyakhiwe izibuko zangaphambili nezangemuva, kanye neyunithi yesihlungi sokukhetha imodi yokubona. Ekugcineni, ngokulungisa ubude bomgodi wokubonisa, isihlungi semodi yokubona singafinyelela ekuphumeni kokukhetha ubude beza.

Indlela yokulungisa nokutholakala kwayo

Umgomo wokushuna we-tuningi-semiconductor laserskuncike kakhulu ekuguquleni amapharamitha aphathekayo we-laser resonator ukuze kuzuzwe izinguquko eziqhubekayo noma ezihlukene kubude beza beza be-laser okukhiphayo. Lezi zinhlaka zihlanganisa, kodwa azikhawulelwe, inkomba ye-refractive, ubude bomgodi, nokukhetha imodi. Lokhu okulandelayo kuchaza izindlela ezimbalwa ezivamile zokushuna nezimiso zazo:

1. Ukulungiswa komjovo wenkampani yenethiwekhi

Ukushuna komjovo wenkampani yenethiwekhi ukushintsha inkomba ye-refractive yento ngokushintsha yamanje ejovwe endaweni esebenzayo ye-semiconductor laser, ukuze kuzuzwe ukushuna kwe-wavelength. Uma ukwanda kwamanje, ukugxila kwenkampani yenethiwekhi kuyanda, okuholela ekushintsheni kwenkomba ye-refractive, okubuye kuthinte ubude be-laser.

2. Ukushuna okushisayo Ukushuna okushisayo ukushintsha inkomba ye-refractive kanye nobude bembobo yento ngokushintsha izinga lokushisa lokusebenza le-laser, ukuze kuzuzwe ukushuna kwe-wavelength. Ukushintsha kwezinga lokushisa kuthinta inkomba ye-refractive kanye nosayizi womzimba wento.

3. Ukushuna ngomshini Ukushuna kwemishini iwukuzuza ukushuna kwe-wavelength ngokushintsha indawo noma i-Engeli yezinto zangaphandle zangaphandle ze-laser. Izindlela ezivamile zokulungisa imishini zihlanganisa ukushintsha i-engeli ye-diffraction grating nokuhambisa indawo yesibuko.

4 Ukushuna kwe-Electro-optical Ukushuna kwe-electro-optical kufinyelelwa ngokusebenzisa indawo kagesi kumpahla ye-semiconductor ukushintsha inkomba ye-refractive yento, ngaleyo ndlela kuzuzwe ukushunwa kwe-wavelength. Le ndlela isetshenziswa kakhulu kuama-modulators e-electro-optical (I-EOM) kanye namalaser ashunwe nge-electro-optically.

Kafushane, umgomo wokushuna we-laser ye-semiconductor eguqulekayo ikakhulukazi ibona ukushuna kwe-wavelength ngokushintsha amapharamitha aphathekayo we-resonator. Le mingcele ihlanganisa inkomba ye-refractive, ubude be-cavity, nokukhetha imodi. Izindlela zokulungisa eziqondile zifaka ukushunwa komjovo wenkampani yenethiwekhi, ukulungisa okushisayo, ukushuna komshini kanye nokushuna kwe-electro-optical. Indlela ngayinye inomshini wayo othize obonakalayo kanye nokuphuma kwezibalo, futhi ukukhethwa kwendlela yokushuna efanele kudingeka kucatshangelwe ngokuvumelana nezidingo ezithile zohlelo lokusebenza, njengobubanzi bokushuna, isivinini sokushuna, ukulungiswa nokuzinza.
