Koho o ke kūlana kūponokumu laser: laser semiconductor hoʻokuʻu lihi
1. Hoʻolauna
Laser semiconductorUa māhele ʻia nā ʻāpana i nā ʻāpana laser emitting edge (EEL) a me nā ʻāpana laser emitting surface cavity vertical (VCSEL) e like me nā kaʻina hana hana like ʻole o nā resonators, a ua hōʻike ʻia ko lākou ʻokoʻa kūkulu kikoʻī ma ke Kiʻi 1. Ke hoʻohālikelike ʻia me ka laser emitting surface cavity vertical, ʻoi aku ka oʻo o ka hoʻomohala ʻana o ka ʻenehana laser semiconductor emitting edge, me kahi laulā wavelength ākea, kiʻekiʻeuila-ʻōpikoka pono o ka hoʻololi ʻana, ka mana nui a me nā pono ʻē aʻe, kūpono loa no ka hana laser, ke kamaʻilio optical a me nā kahua ʻē aʻe. I kēia manawa, he ʻāpana koʻikoʻi nā lasers semiconductor edge-emitting o ka ʻoihana optoelectronics, a ua uhi kā lākou noi i ka ʻoihana, ke kelepona, ka ʻepekema, ka mea kūʻai aku, ka pūʻali koa a me ka aerospace. Me ka hoʻomohala ʻana a me ka holomua o ka ʻenehana, ua hoʻomaikaʻi nui ʻia ka mana, ka hilinaʻi a me ka pono o ka hoʻololi ikehu o nā lasers semiconductor edge-emitting, a ua ʻoi aku ka laulā o kā lākou mau manaʻolana noi.
ʻO ka mea aʻe, e alakaʻi wau iā ʻoe e mahalo hou aku i ka ʻano hoʻohiwahiwa o ka hoʻokuʻu ʻaoʻaonā lasers semiconductor.

Kiʻi 1 (hema) ʻaoʻao e hoʻopuka ana i ka laser semiconductor a me (ʻākau) kiʻikuhi hoʻonohonoho laser e hoʻopuka ana i ka ʻili lua kū pololei

2. Kumu hana o ka semiconductor hoʻokuʻu lihilaser
Hiki ke hoʻokaʻawale ʻia ke ʻano o ka laser semiconductor edge-emitting i ʻekolu ʻāpana: ka ʻāpana hana semiconductor, ke kumu pump a me ka resonator optical. ʻOkoʻa mai nā resonators o nā lasers edge-emitting surface (i haku ʻia me nā aniani Bragg luna a me lalo), ʻo nā resonators i nā mea hana laser semiconductor edge-emitting i haku nui ʻia me nā kiʻiʻoniʻoni optical ma nā ʻaoʻao ʻelua. Hōʻike ʻia ke ʻano o ka mea hana EEL maʻamau a me ke ʻano resonator ma ke Kiʻi 2. Hoʻonui ʻia ka photon i loko o ka mea hana laser semiconductor edge-emission e ke koho ʻano i loko o ka resonator, a ua hana ʻia ka laser ma ke kuhikuhi e like me ka ʻili substrate. Loaʻa i nā mea hana laser semiconductor edge-emitting kahi ākea o nā nalu hana a kūpono no nā noi hana he nui, no laila lilo lākou i hoʻokahi o nā kumu laser kūpono.

ʻO nā ʻōkuhi loiloi hana o nā lasers semiconductor edge-emitting e kūlike pū me nā lasers semiconductor ʻē aʻe, me: (1) ka nalu laser lasing; (2) Ke au paepae Ith, ʻo ia hoʻi, ke au e hoʻomaka ai ka diode laser e hana i ka oscillation laser; (3) Ke au hana Iop, ʻo ia hoʻi, ke au hoʻokele i ka wā e hiki ai ka diode laser i ka mana hoʻopuka i helu ʻia, ua hoʻopili ʻia kēia parameter i ka hoʻolālā a me ka modulation o ke kaapuni hoʻokele laser; (4) Ka pono o ka pali; (5) Vertical divergence Angle θ⊥; (6) Horizontal divergence Angle θ∥; (7) E nānā i ke au Im, ʻo ia hoʻi, ka nui o ke au o ka chip laser semiconductor ma ka mana hoʻopuka i helu ʻia.

3. Holomua noiʻi o nā lasers semiconductor e hoʻopuka ana i ka lihi GaAs a me GaN
ʻO ka laser semiconductor e pili ana i ka mea semiconductor GaAs kekahi o nā ʻenehana laser semiconductor makua loa. I kēia manawa, ua hoʻohana nui ʻia nā lasers semiconductor edge-emitting band kokoke-infrared (760-1060 nm) e pili ana i ka GAAS ma ke kālepa. Ma ke ʻano he mea semiconductor hanauna ʻekolu ma hope o Si a me GaAs, ua pili nui ʻo GaN i ka noiʻi ʻepekema a me ka ʻoihana ma muli o kona mau waiwai kino a me ke kemika maikaʻi loa. Me ka hoʻomohala ʻana o nā mea optoelectronic e pili ana i ka GAN a me nā hana a nā mea noiʻi, ua hoʻomohala ʻia nā diode light-emitting e pili ana i ka GAN a me nā lasers e pili ana i ka ʻoihana.
