VCSEL, oo loo yaqaan 'Vertical Cavity Surface Emitting Laser' oo buuxa, waa nooc ka mid ah leysarka semiconductor.Hadda, VCSEL-yada intooda badani waxay ku salaysan yihiin gaAs semiconductors, iyo dhererka hirarka sii daaya inta badan waxay ku jiraan band mowjadaha infrared.
Sannadkii 1977-kii, Professor Ika Kenichi oo ka tirsan Jaamacadda Teknolojiyadda ee Tokyo ayaa markii ugu horreysay soo jeediyay fikradda leysarka dusha sare ee daloolka toosan.Maalmihii hore, waxa uu inta badan rabay in uu helo hal leyser oo ah qaab-dherer ah oo leh wax soo saar deggan isaga oo soo gaabinaya dhererka daloolka.Si kastaba ha ahaatee, dhererka faa'iidada hal-jidka ah ee nashqadan oo gaaban awgeed, waxa ay ahayd mid adag in la helo laysarka laysarka, sidaa awgeed cilmi-baadhistii hore ee VCSEL waa la sii dheeraaday.Laba sano ka dib, Professor Yihe Jianyi wuxuu si guul leh u xaqiiqsaday lasing lasing of GaInAsP lasers taxane at 77 K iyadoo la isticmaalayo teknoolajiyada dareeraha wajiga epitaxy (habka dareeraha-wejiga epitaxy si ay u soo dedejiso walxaha adag ee xal iyo iyaga ku shubaa substrate si ay u abuuraan lakabyo khafiif ah hal-crystal ).Sannadkii 1988-kii, VCSEL-yada taxanaha ah ee GaAs waxaa koray tignoolajiyada kaydinta uumiga kiimikada organic (OCVD) si loo gaadho hawlgal joogto ah oo heerkulka qolka ah.Iyadoo horumarinta joogtada ah ee tignoolajiyada epitaxial, qaab-dhismeedka semiconductor DBR oo leh milicsi sare ayaa la soo saari karaa, taas oo si weyn u dedejisa habka cilmi-baarista ee VCSEL.Dhammaadkii qarnigii 20-aad, ka dib markii hay'adaha cilmi-baaristu ay tijaabiyeen qaabab kala duwan, heerka caadiga ah ee VCSEL-ka xaddidan ee oksaydhka ayaa si aad ah loo dejiyay.Kadibna waxay u dhaqaaqday marxaladda qaan-gaadhnimada, halkaas oo waxqabadka si joogto ah loo hagaajiyay lana hagaajiyay.
Jaantuska qaybaha ee oksaydhisku xaddiday laser-ka sare ee sii daaya
Gobolka firfircooni waa qaybta muhiimka ah ee qalabka.Sababtoo ah godka VCSEL waa mid aad u gaaban, dhexdhexaadiyaha firfircoon ee godka wuxuu u baahan yahay inuu bixiyo magdhow dheeraad ah oo loogu talagalay habka lasinta.
Ugu horreyn, saddex shuruudood waa in si isku mar ah loo buuxiyo si loo soo saaro laysarka:
1) qaybinta rogan sideyaasha ee gobolka firfircoon ayaa la aasaasay;
2) dalool resonant ku habboon wuxuu u oggolaanayaa shucaaca la kiciyey in marar badan dib loo quudiyo si loo sameeyo oscillation laser;iyo
3) duritaanka hadda waa mid xoogan oo ku filan si ay uga dhigto faa'iidada indhaha ka weyn ama la mid ah wadarta khasaaraha kala duwan oo ay la kulanto shuruudo xaddidan oo hadda jira.
Saddexda xaaladood ee aasaasiga ah waxay u dhigmaan fikradda naqshadaynta qaab dhismeedka aaladda VCSEL.Gobolka firfircoon ee VCSEL wuxuu isticmaalaa qaab-dhismeedka ceelka tirada dhibban si loo dhiso aasaaska xaqiijinta qaybinta roganta gudbiyaha gudaha.Isla mar ahaantaana, dalool sanqadha leh oo leh milicsi habboon ayaa loo qaabeeyey si uu sawir-qaadayaasha la sii daayo u sameeyaan dhaqdhaqaaq isku xidhan.Ugu dambeyntii, hadda ku filan oo duritaanka ah ayaa la bixiyaa si ay awood ugu siiso sawir-qaadayaasha inay ka gudbaan khasaaraha kala duwan ee qalabka laftiisa si loo abuuro mid waara
Tani waa sida Shenzhen HDV Optoelectronic Technology Co., Ltd., shirkad isgaarsiin indhaha, sharaxay VCSEL.
