Chiyambi cha Edge Emitting Laser (EEL)
Kuti mupeze zotulutsa zamphamvu kwambiri za semiconductor laser, ukadaulo wapano ndikugwiritsa ntchito mawonekedwe am'mphepete. The resonator ya m'mphepete-emitting semiconductor laser amapangidwa ndi chilengedwe dissociation pamwamba pa semiconductor kristalo, ndi mtengo linanena bungwe limatulutsa kuchokera kumapeto kwa laser.The m'mphepete-emission mtundu semiconductor laser akhoza kupeza mphamvu kutulutsa mphamvu, koma zotuluka malo ake ndi elliptical, mtengo mtengo khalidwe ndi osauka, ndipo mawonekedwe a mtengo ndi modified mawonekedwe.
Chithunzi chotsatirachi chikuwonetsa mawonekedwe a laser semiconductor laser. Mphepete mwa kuwala kwa EEL ndi yofanana ndi pamwamba pa semiconductor chip ndipo imatulutsa laser m'mphepete mwa semiconductor chip, yomwe imatha kuzindikira kutulutsa kwa laser ndi mphamvu yayikulu, kuthamanga kwambiri komanso phokoso lochepa. Komabe, mtengo wa laser wopangidwa ndi EEL nthawi zambiri umakhala ndi gawo la mtanda wa asymmetric ndi kusiyana kwakukulu kwa angular, ndipo kugwirizanitsa bwino ndi fiber kapena zinthu zina zowoneka ndizochepa.

Kuwonjezeka kwa mphamvu ya EEL yotulutsa mphamvu kumakhala kochepa chifukwa cha kutentha kwa zinyalala m'dera logwira ntchito komanso kuwonongeka kwa kuwala pa semiconductor pamwamba. Ndi kuonjezera dera waveguide kuchepetsa zinyalala kutentha kudzikundikira m'dera yogwira kusintha kutentha kuziika, kuwonjezera kuwala linanena bungwe m'dera kuchepetsa kuwala mphamvu kachulukidwe wa mtengo kupewa kuwonongeka kuwala, mphamvu linanena bungwe la mpaka mazana angapo milliwatts chingapezeke mu umodzi yopingasa mode waveguide dongosolo.
Kwa 100mm waveguide, laser imodzi yotulutsa m'mphepete imatha kupeza ma Watts ambiri amphamvu, koma panthawiyi ma waveguide ali ndimitundu yambiri pa ndege ya chip, ndipo chiwongolero cha mtengo wotulutsa chimafikanso 100: 1, zomwe zimafunikira dongosolo lopanga mtengo.
Poganizira kuti palibe kutulukira kwatsopano muukadaulo wazinthu komanso ukadaulo wakukula kwa epitaxial, njira yayikulu yopititsira patsogolo mphamvu ya chipangizo cha semiconductor laser chip ndikuwonjezera m'lifupi m'lifupi mwa dera lowala la chip. Komabe, kuwonjezera Mzere m'lifupi kwambiri n'zosavuta kubala yopingasa mkulu-kuti mode oscillation ndi filamentlike oscillation, amene kwambiri kuchepetsa kufanana kwa linanena bungwe kuwala, ndi linanena bungwe mphamvu si kuwonjezeka molingana ndi m'lifupi Mzere, kotero linanena bungwe mphamvu ya Chip limodzi ndi zochepa kwambiri. Kuti apititse patsogolo kwambiri mphamvu zotulutsa, ukadaulo wa array umabwera. Ukadaulo umaphatikiza mayunitsi angapo a laser pagawo lomwelo, kotero kuti gawo lililonse lotulutsa kuwala limakhala ngati gulu limodzi loyenda pang'onopang'ono, bola ngati ukadaulo wodzipatula umagwiritsidwa ntchito kulekanitsa gawo lililonse lotulutsa kuwala, kuti zisasokoneze wina ndi mnzake, kupanga mawonekedwe amtundu wamitundu yambiri, mutha kukulitsa kuchuluka kwa mphamvu yophatikizika ya chipangizocho. Chip cha laser cha semiconductor ndi semiconductor laser array (LDA) chip, chomwe chimadziwikanso kuti semiconductor laser bar.
