ʻO ke koho kūponopuna laser: laser semiconductor hoʻokuʻu ʻia
1. Hoʻolauna
Semiconductor laserUa mahele ʻia nā ʻāpana i nā ʻāpana laser edge emitting (EEL) a me nā ʻāpana kūwaho kūwaho emitting laser chips (VCSEL) e like me nā kaʻina hana hana like ʻole o nā resonators, a ua hōʻike ʻia kā lākou mau ʻokoʻa kikoʻī kikoʻī ma ke Kiʻi 1. Ke hoʻohālikelike ʻia me ka ʻaoʻao o ka lua kupapaʻu e hoʻokuʻu ana i ka laser, lihi. ʻO ka hoʻomohala ʻana i ka ʻenehana laser semiconductor ʻoi aku ka makua, me kahi ākea ākea ākea, kiʻekiʻeelectro-opticalka pono o ka hoʻololi ʻana, ka mana nui a me nā pono ʻē aʻe, kūpono loa no ka hoʻoponopono laser, kamaʻilio optical a me nā māla ʻē aʻe.I kēia manawa, he ʻāpana koʻikoʻi nā lasers semiconductor edge-emitting o ka ʻoihana optoelectronics, a ua uhi kā lākou mau noi i ka ʻoihana, kelepona, ʻepekema, mea kūʻai aku, pūʻali koa a me ka aerospace.Me ka hoʻomohala ʻana a me ka holomua o ka ʻenehana, ua hoʻomaikaʻi maikaʻi ʻia ka mana, hilinaʻi a me ka hoʻololi ʻana i ka ikehu o nā laser semiconductor edge-emitting, a ʻoi aku ka nui o kā lākou noi noi.
Ma hope aʻe, e alakaʻi wau iā ʻoe e mahalo hou i ka nani kūʻokoʻa o ka ʻaoʻao-emittingnā laser semiconductor.
Kiʻi 1 (hema) ʻaoʻao e hoʻokuʻu ana i ka laser semiconductor a me (ʻākau) ka ʻaoʻao o ka lua kū pololei e hoʻokuʻu ana i ke kiʻi hoʻolālā laser.
2. Ka loina hana o ka semiconductor emission edgelaser
Hiki ke hoʻokaʻawale ʻia ke ʻano o ka laser semiconductor edge-emitting i ʻekolu mau ʻāpana: semiconductor active region, pump source and optical resonator.ʻOkoʻa mai nā resonators o nā lasers e hoʻoheheʻe ʻia i ka ʻaoʻao o ka lua kupapaʻu (ʻo ia ka mea i haku ʻia me nā aniani o luna a me lalo o Bragg), ʻo nā resonator ma nā ʻaoʻao laser semiconductor edge-emitting ka mea nui i nā kiʻiʻoniʻoni ma nā ʻaoʻao ʻelua.Hōʻike ʻia ke ʻano mea hana EEL maʻamau a me ke ʻano resonator ma ke Kiʻi 2. Hoʻonui ʻia ka photon i loko o ka mīkini laser semiconductor edge-emission e ke koho mode i ka resonator, a ua hoʻokumu ʻia ka laser ma ke ala e like me ka ʻili o ka substrate.Loaʻa i nā hāmeʻa laser semiconductor e hoʻokuʻu ana i ka ʻaoʻao i kahi ākea o nā nalu hana a kūpono i nā noi hana he nui, no laila ua lilo lākou i hoʻokahi o nā kumu laser kūpono.
Ua kūlike pū nā papa kuhikuhi loiloi hana o nā laser semiconductor edge-emitting me nā laser semiconductor ʻē aʻe, e like me: (1) ka lōʻihi o ka hawewe lasing laser;(2) ʻO ka paepae o kēia manawa Ith, ʻo ia hoʻi, ke au i hoʻomaka ai ka diode laser e hana i ka oscillation laser;(3) Iop hana i kēia manawa, ʻo ia hoʻi, ke kalaiwa hoʻokele i ka wā e hiki ai ka diode laser i ka mana hoʻopuka helu ʻia, ua hoʻohana ʻia kēia ʻāpana i ka hoʻolālā a me ka modulation o ke kaapuni kaʻa laser;(4) Pono ka pali;(5) ʻAmi ʻokoʻa kū pololei θ⊥;(6) ʻAkiʻi ʻokoʻa ʻākau θ∥;(7) E nānā i ka Im o kēia manawa, ʻo ia hoʻi, ka nui o kēia manawa o ka chip laser semiconductor ma ka mana hoʻopuka helu.
3. Ka holomua noiʻi o GaAs a me GaN e hoʻokuʻu ana i nā laser semiconductor
ʻO ka laser semiconductor e pili ana i nā mea semiconductor GaAs kekahi o nā ʻenehana laser semiconductor ʻoi loa.I kēia manawa, ua hoʻohana nui ʻia nā lasers semiconductor edge-emitting edge-emitting i kēia manawa, GAAS-based near-infrared band.ʻOiai ʻo ke kolu o ka hanauna semiconductor material ma hope o Si a me GaAs, ua hopohopo nui ʻo GaN i ka noiʻi ʻepekema a me ka ʻoihana ma muli o kāna mau waiwai kino a me nā kemika.Me ka hoʻomohala ʻana o nā mea hana optoelectronic e pili ana i ka GAN a me ka hoʻoikaika ʻana o nā mea noiʻi, ua hoʻomohala ʻia nā diodes kukui-emitting a me nā laser edge-emitting.
