4. Boemo ba ts'ebeliso ea li-laser tsa semiconductor tsa bohale-mosi
Ka lebaka la mefuta e mengata ea maqhubu a eona le matla a eona a phahameng, li-laser tsa semiconductor tse ntšang mahlakore li sebelisitsoe ka katleho masimong a mangata a kang a likoloi, puisano ea mahlo lelaserkalafo ea bongaka. Ho ea ka Yole Developpement, setsi se tummeng sa lipatlisiso tsa 'maraka sa machaba, 'maraka oa laser o ka pele ho emit o tla hola ho fihlela ho $7.4 bilione ka 2027, ka sekhahla sa kholo ea selemo le selemo sa 13%. Kholo ena e tla tsoela pele ho tsamaisoa ke puisano ea mahlo, joalo ka li-module tsa mahlo, li-amplifier, le lits'ebetso tsa ho lemoha tsa 3D bakeng sa puisano ea data le puisano ea mohala. Bakeng sa litlhoko tse fapaneng tsa ts'ebeliso, merero e fapaneng ea moralo oa sebopeho sa EEL e ntlafalitsoe indastering, ho kenyeletsoa: li-laser tsa semiconductor tsa Fabripero (FP), li-laser tsa semiconductor tsa Distributed Bragg Reflector (DBR), li-laser tsa semiconductor tsa external cavity laser (ECL), li-laser tsa semiconductor tse ajoang ka maikutlo (Lesetara ea DFB), li-laser tsa semiconductor tsa quantum cascade (QCL), le li-diode tsa laser tsa sebaka se seholo (BALD).

Ka tlhoko e ntseng e eketseha ea puisano ea mahlo, lits'ebetso tsa ho lemoha tsa 3D le masimo a mang, tlhoko ea li-laser tsa semiconductor le eona ea eketseha. Ho phaella moo, li-laser tsa semiconductor tse ntšang mathōko le li-laser tsa semiconductor tse ntšang mathōko holim'a metsi tse otlolohileng le tsona li bapala karolo ea ho tlatsa mefokolo ea e mong le 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 li sebelisoa hangata libakeng tsa phetisetso tsa 2 km ho isa ho 40 km 'me sekhahla sa phetisetso se fihla ho 40 Gbps. Leha ho le joalo, libakeng tsa phetisetso tsa 60 m ho isa ho 300 m le lebelo le tlase la phetisetso, li-VCsel tse ipapisitseng le 850 nm InGaAs le AlGaAs li atile.
(2) Li-laser tse ntšang bokaholimo bo otlolohileng li na le melemo ea boholo bo bonyenyane le bolelele ba maqhubu bo bonyenyane, kahoo li 'nile tsa sebelisoa haholo' marakeng oa lisebelisoa tsa elektroniki tsa bareki, 'me melemo ea khanya le matla a li-laser tsa semiconductor tse ntšang bohale li bula tsela bakeng sa lits'ebetso tsa ho lemoha hole le ts'ebetso ea matla a phahameng.
(3) Li-laser tsa semiconductor tse ntšang mathōkong le li-laser tsa semiconductor tse ntšang mathōkong a otlolohileng li ka sebelisoa bakeng sa liDAR tse khutšoane le tse mahareng ho fihlela lits'ebetso tse itseng tse kang ho lemoha libaka tse sa boneng le ho tloha tseleng.

5. Nts'etsopele ea nakong e tlang
Laser ea semiconductor e ntšang mahlakore e na le melemo ea ho tšepahala ho hoholo, ho fokotsa matla le ho ba le matla a mangata a khanyang, 'me e na le menyetla e mengata ea ts'ebeliso puisanong ea optical, liDAR, bongaka le mafapheng a mang. Leha ho le joalo, leha ts'ebetso ea tlhahiso ea li-laser tsa semiconductor tse ntšang mahlakore e se e hōlile haholo, e le ho fihlela tlhoko e ntseng e hola ea limmaraka tsa indasteri le tsa bareki bakeng sa li-laser tsa semiconductor tse ntšang mahlakore, ho hlokahala hore ho ntlafatsoe theknoloji, ts'ebetso, ts'ebetso le likarolo tse ling tsa li-laser tsa semiconductor tse ntšang mahlakore, ho kenyeletsoa: ho fokotsa bongata ba sekoli ka har'a wafer; Fokotsa mekhoa ea ts'ebetso; Ntlafatsa mahlale a macha ho nkela mekhoa ea setso ea ho seha lebili la ho sila le la blade wafer e kotsing ea ho hlahisa liphoso; Ntlafatsa sebopeho sa epitaxial ho ntlafatsa katleho ea laser e ntšang mahlakore; Fokotsa litšenyehelo tsa tlhahiso, jj. Ho feta moo, hobane leseli la tlhahiso ea laser e ntšang mahlakore le ka lehlakoreng la chip ea laser ea semiconductor, ho thata ho fihlela sephutheloana sa chip se senyenyane, kahoo ts'ebetso e amanang le sephutheloana e ntse e hloka ho rarolloa haholoanyane.
