Gabatarwa zuwa Edge Emitting Laser (EEL)
Domin samun babban ƙarfin wutar lantarki semiconductor Laser, fasaha na yanzu shine amfani da tsarin fitar da iska. The resonator na gefen-emitting semiconductor Laser ya hada da na halitta dissociation surface na semiconductor crystal, da kuma fitarwa katako da aka emitted daga gaban karshen Laser.The gefen-emitting nau'in semiconductor Laser iya cimma babban iko fitarwa, amma ta. Wurin fitarwa yana da elliptical, ingancin katako ba shi da kyau, kuma ana buƙatar gyara siffar katako tare da tsarin ƙirar katako.
Hoton da ke gaba yana nuna tsarin laser semiconductor mai fitar da baki. Ramin gani na EEL yana daidai da saman guntu na semiconductor kuma yana fitar da Laser a gefen guntu na semiconductor, wanda zai iya gane fitowar laser tare da babban iko, babban gudu da ƙaramar amo. Koyaya, fitarwar Laser ta EEL gabaɗaya yana da sashin giciye na katako mai asymmetric da babban bambance-bambancen angular, kuma haɓakar haɗakarwa tare da fiber ko wasu abubuwan haɗin gani yana da ƙasa.

Haɓaka ƙarfin fitarwa na EEL yana iyakance ta hanyar tara zafin sharar gida a cikin yanki mai aiki da lalacewar gani akan saman semiconductor. Ta hanyar haɓaka yankin waveguide don rage yawan tarawar sharar gida a cikin yanki mai aiki don inganta yanayin zafi, ƙara yawan hasken wutar lantarki don rage yawan ƙarfin wutar lantarki na katako don kauce wa lalacewa na gani, ƙarfin fitarwa har zuwa daruruwan milliwatts na iya. za a samu a cikin tsari guda ɗaya mai jujjuya waveguide.
Domin 100mm waveguide, guda gefen-emitting Laser iya cimma dubun watts na fitarwa ikon, amma a wannan lokacin da waveguide ne sosai Multi-yanayin a kan jirgin na guntu, da kuma fitarwa al'amari rabo kuma kai 100: 1, yana buƙatar tsarin tsarin ƙirar katako mai rikitarwa.
Dangane da cewa babu wani sabon ci gaba a cikin fasahar kayan abu da fasahar haɓaka epitaxial, babbar hanyar haɓaka ƙarfin fitarwa na guntu Laser na semiconductor guda ɗaya shine ƙara girman tsiri na yanki mai haske na guntu. Duk da haka, ƙara da tsiri nisa ma high ne mai sauki don samar da transverse high-oda yanayin oscillation da filamentlike oscillation, wanda zai ƙwarai rage uniformity na haske fitarwa, da kuma fitarwa ikon ba ya karu proportionally tare da tsiri nisa, don haka da fitarwa ikon. guntu guda yana da iyaka. Domin inganta ƙarfin fitarwa sosai, fasahar tsararru ta zo cikin kasancewa. Fasahar tana haɗa raka'o'in Laser da yawa akan ma'auni guda ɗaya, ta yadda kowace na'ura mai fitar da haske ta jera a jere a matsayin jeri mai girman fuska ɗaya a cikin sannu a hankali, muddin ana amfani da fasahar keɓewar gani don raba kowace na'ura mai fitar da haske a cikin tsararru. , don kada su tsoma baki tare da juna, samar da Multi-bude lasing, za ka iya ƙara da fitarwa ikon dukan guntu ta ƙara yawan hadedde haske emitting raka'a. Wannan guntu Laser guntu na semiconductor guntu ce ta Laser array (LDA), wanda kuma aka sani da sandar Laser semiconductor.
