1. Selelekela
Lesetara ea semiconductorLi-chip li arotsoe ka li-chip tsa laser tse ntšang mahlakore a ka holimo (EEL) le li-chip tsa laser tse ntšang mahlakore a ka holimo a ka holimo a ka holimo (VCSEL) ho latela mekhoa e fapaneng ea tlhahiso ea li-resonator, 'me liphapang tsa tsona tse ikhethang tsa sebopeho li bontšitsoe ho Setšoantšo sa 1. Ha li bapisoa le laser e ntšang mahlakore a ka holimo a ka holimo a ka holimo, nts'etsopele ea theknoloji ea laser e ntšang mahlakore a ka holimo e holile haholoanyane, e nang le mefuta e mengata ea maqhubu a bolelele ba leqhubu, e phahameng.motlakase-opticalbokgoni ba phetoho, matla a maholo le melemo e meng, e loketse haholo bakeng sa ts'ebetso ea laser, puisano ea optical le masimo a mang. Hona joale, li-laser tsa semiconductor tse ntšang mahlakore ke karolo ea bohlokoa ea indasteri ea optoelectronics, 'me lits'ebetso tsa tsona li akarelitse indasteri, puisano ea mohala, saense, bareki, sesole le sefofane. Ka nts'etsopele le tsoelo-pele ea theknoloji, matla, ts'epo le bokhoni ba phetoho ea matla ba li-laser tsa semiconductor tse ntšang mahlakore bo ntlafalitsoe haholo, 'me menyetla ea ts'ebeliso ea tsona e pharaletse haholo.
Ka mor'a moo, ke tla u tataisa hore u ananele haholoanyane botle bo ikhethang ba ho ntša lintho tse lingli-laser tsa semiconductor.

Setšoantšo sa 1 (ka letsohong le letšehali) sa laser ea semiconductor e ntšang lehlakore le (ka ho le letona) setšoantšo sa sebopeho sa laser e ntšang bokaholimo bo otlolohileng

2. Molao-motheo oa ho sebetsa oa semiconductor ea mosi o tsoang moelinglaser
Sebopeho sa laser ea semiconductor e ntšang mahlakore se ka aroloa ka likarolo tse tharo tse latelang: sebaka se sebetsang sa semiconductor, mohloli oa pompo le resonator ea optical. Ho fapana le li-resonator tsa laser tse ntšang bokaholimo tse otlolohileng (tse entsoeng ka liipone tsa Bragg tse holimo le tse tlase), li-resonator tse sebelisoang lisebelisoa tsa laser tsa semiconductor tse ntšang mahlakore li entsoe haholo-holo ka lifilimi tsa optical mahlakoreng ka bobeli. Sebopeho se tloaelehileng sa sesebelisoa sa EEL le sebopeho sa resonator li bontšitsoe ho Setšoantšo sa 2. Photon e sesebelisoa sa laser ea semiconductor e ntšang mahlakore e matlafatsoa ke khetho ea mokhoa ho resonator, 'me laser e thehoa ka lehlakoreng le bapileng le bokaholimo ba substrate. Lisebelisoa tsa laser tsa semiconductor tse ntšang mahlakore li na le mefuta e mengata ea maqhubu a sebetsang 'me li loketse lits'ebetso tse ngata tse sebetsang, kahoo li fetoha e 'ngoe ea mehloli e loketseng ea laser.

Li-index tsa tlhahlobo ea ts'ebetso ea li-laser tsa semiconductor tse ntšang motlakase ka lehlakoreng le leng li lumellana le li-laser tse ling tsa semiconductor, ho kenyeletsoa: (1) bolelele ba leqhubu ba laser; (2) Khoeli ea Threshold Ith, ke hore, hona joale moo diode ea laser e qalang ho hlahisa ho sisinyeha ha laser; (3) Iop ea hona joale e sebetsang, ke hore, hona joale e khannang ha diode ea laser e fihla matla a tlhahiso a lekantsoeng, paramethara ena e sebelisoa ho moralo le modulation ea potoloho ea drive ea laser; (4) Bokhoni ba ho thella; (5) Angle ea ho fapana ka lehlakoreng le otlolohileng θ⊥; (6) Angle ea ho fapana ka lehlakoreng le otlolohileng θ∥; (7) Lekola Im ea hona joale, ke hore, boholo ba hona joale ba chip ea laser ea semiconductor matleng a tlhahiso a lekantsoeng.

3. Tswelopele ya dipatlisiso tsa GaAs le GaN based edge emitting semiconductor lasers
Laser ea semiconductor e thehiloeng holim'a thepa ea semiconductor ea GaAs ke e 'ngoe ea mahlale a laser ea semiconductor a hōlileng ka ho fetisisa. Hona joale, li-laser tsa semiconductor tse thehileng haufi le infrared band (760-1060 nm) tse sebelisang mahlakore a semiconductor li sebelisitsoe haholo khoebong. Jwalo ka thepa ea semiconductor ea moloko oa boraro kamora Si le GaAs, GaN e 'nile ea ameha haholo lipatlisisong tsa mahlale le indastering ka lebaka la thepa ea eona e ntle ea' mele le ea lik'hemik'hale. Ka nts'etsopele ea lisebelisoa tsa optoelectronic tse thehiloeng ho GAN le boiteko ba bafuputsi, li-diode tse sebelisang mabone tse thehiloeng ho GAN le li-laser tse sebelisang mahlakore a semiconductor li se li ntlafalitsoe.
