Gabatarwa zuwa Edge Emitting Laser (EEL)

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 ne hada da na halitta dissociation surface na semiconductor crystal, da kuma fitarwa katako da aka emitted daga gaban karshen Laser.The gefen- watsi irin semiconductor Laser iya cimma babban iko fitarwa, amma ta fitarwa tabo ne elliptical, da katako ingancin ne matalauta, da katako siffar bukatar da za a modified da tsarin.
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, za'a iya samun ikon fitarwa har zuwa ɗaruruwan milliwatts da yawa a cikin tsari guda ɗaya mai jujjuyawa yanayin waveguide.
Domin 100mm waveguide, guda gefu-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 ya kai 100: 1, na bukatar hadaddun katako siffata tsarin.
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. Koyaya, ƙara girman tsiri da tsayi yana da sauƙi don samar da yanayin jujjuyawar yanayin yanayi mai jujjuyawa da oscillation kamar filament, wanda zai rage daidaituwar fitowar haske sosai, kuma ƙarfin fitarwa ba ya ƙaruwa daidai gwargwado tare da faɗin tsiri, don haka ikon fitarwa na guntu ɗaya yana da iyaka. Domin inganta ƙarfin fitarwa sosai, fasahar tsararru ta zo cikin kasancewa. The fasaha integrates mahara Laser raka'a a kan wannan substrate, sabõda haka, kowane haske emitting naúrar aka jeri a matsayin daya-girma tsararru a cikin jinkirin axis shugabanci, muddin da Tantancewar kadaici fasaha da ake amfani da su raba kowane haske emitting naúrar a cikin tsararru, sabõda haka, ba su tsoma baki tare da juna, forming Multi-bude lasing, za ka iya ƙara da guntu fitarwa ikon naúrar gaba daya. Wannan guntu Laser guntu na semiconductor guntu ce ta Laser array (LDA), wanda kuma aka sani da sandar Laser semiconductor.
