4. Boemo ba tšebeliso ea li-lasers tsa semiconductor tse bohale
Ka lebaka la boholo ba eona bo pharaletseng ba maqhubu le matla a phahameng, li-lasers tsa semiconductor tse hlahisang moeli li sebelisitsoe ka katleho mafapheng a mangata a kang likoloi, puisano ea optical le.laserphekolo ea meriana. Ho ea ka Yole Developpement, setsi se tsebahalang lefatšeng ka bophara sa lipatlisiso tsa mebaraka, mmaraka oa laser-to-emit o tla hola ho $7.4 bilione ka 2027, ka sekhahla sa kholo ea selemo le selemo sa 13%. Khōlo ena e tla tsoela pele ho tsamaisoa ke puisano ea optical, e kang optical modules, amplifiers, le lisebelisoa tsa 3D sensing bakeng sa puisano ea data le mehala ea puisano. Bakeng sa litlhoko tse fapaneng tsa kopo, merero e fapaneng ea meralo ea sebopeho sa EEL e entsoe indastering, ho kenyelletsa le: Fabripero (FP) semiconductor lasers, Distributed Bragg Reflector (DBR) semiconductor lasers, external cavity laser (ECL) semiconductor lasers, distributed feedback semiconductor lasers (DFB laser), li-laser tsa quantum cascade semiconductor lasers (QCL), le li-laser diode tsa sebaka se sephara (BALD).
Ka tlhokahalo e ntseng e eketseha ea puisano ea optical, likopo tsa 3D sensing le likarolo tse ling, tlhokahalo ea li-lasers tsa semiconductor le eona ea eketseha. Ho feta moo, li-laser tsa semiconductor le li-laser tsa vertical-cavity surface-emitting semiconductor le tsona li phetha karolo ea ho tlatsa mefokolo ea e mong lits'ebetsong tse hlahang, tse kang:
(1) Lefapheng la puisano ea optical, 1550 nm InGaAsP/InP Distributed Feedback ( (DFB laser) EEL le 1300 nm InGaAsP/InGaP Fabry Pero EEL hangata li sebelisoa libakeng tsa phetisetso ea 2 km ho isa ho 40 km le litefiso tsa phetisetso ho fihla ho 40 Gbps Leha ho le joalo, ka 60 m ho 300 limithara phetiso bohole le lebelo le tlase la phetisetso, li-VCsels tse thehiloeng ho 850 nm InGaAs le AlGaAs li atile.
(2) Li-lasers tse otlolohileng tsa "vertical cavity surface-emitting lasers" li na le melemo ea boholo bo bonyenyane le bolelele bo moqotetsane, kahoo li 'nile tsa sebelisoa haholo' marakeng oa lisebelisoa tsa elektroniki tsa bareki, 'me khanya le melemo ea li-laser tsa semiconductor li bula tsela bakeng sa lisebelisoa tsa ho lemoha tse hole. ts'ebetso ea matla a phahameng.

5. Tsoelo-pele ea ka moso
The Edge emitting semiconductor laser e na le melemo ea ts'epo e phahameng, miniaturization le matla a phahameng a khanyang, 'me e na le tebello e pharaletseng ea ts'ebeliso ea puisano ea optical, liDAR, bongaka le likarolo tse ling. Leha ho le joalo, leha ts'ebetso ea tlhahiso ea li-lasers tsa semiconductor e se e holile haholo, e le ho fihlela tlhoko e ntseng e hola ea limmaraka tsa indasteri le bareki bakeng sa li-lasers tsa semiconductor tse sa feleng, hoa hlokahala ho tsoela pele ho ntlafatsa theknoloji, ts'ebetso, ts'ebetso le tse ling. likarolo tsa li-lasers tsa semiconductor tse nang le moeli, ho kenyelletsa le: ho fokotsa sekhahla sa sekoli ka har'a sephaphatha; Fokotsa mekhoa ea ts'ebetso; Theha mahlale a macha a ho nka sebaka sa lebili le silang la setso le lits'ebetso tsa ho seha ka lehare tse tloaetseng ho hlahisa liphoso; Ntlafatsa sebopeho sa epitaxial ho ntlafatsa katleho ea laser e ntšang moeli; Fokotsa litšenyehelo tsa tlhahiso, joalo-joalo Ho phaella moo, hobane khanya e hlahisoang ke laser e ka thōko ho lehlakoreng la semiconductor laser chip, ho thata ho finyella liphutheloana tse nyenyane, kahoo mokhoa o amanang le ho paka o ntse o lokela ho ba teng. ho feta ho phunyeletsoa.
