4. Matsayin aikace-aikacen lasers na semiconductor mai fitar da hayaki daga gefe
Saboda faɗin zangon tsayinsa da ƙarfinsa mai yawa, an yi amfani da na'urorin laser na semiconductor masu fitar da gefuna a fannoni da yawa kamar su mota, sadarwa ta gani da kumalaserMaganin lafiya. A cewar Yole Developmentpement, wata hukumar bincike a kasuwa da ta shahara a duniya, kasuwar laser mai gefe-zuwa-ƙasa za ta karu zuwa dala biliyan 7.4 a shekarar 2027, tare da karuwar ci gaba a kowace shekara da kashi 13%. Wannan ci gaban zai ci gaba da faruwa ne ta hanyar sadarwa ta gani, kamar na'urorin gani, amplifiers, da aikace-aikacen ji na 3D don sadarwa da sadarwa. Don buƙatun aikace-aikace daban-daban, an ƙirƙiri tsare-tsaren ƙira na tsarin EEL daban-daban a masana'antar, waɗanda suka haɗa da: Lasers na semiconductor na Fabripero (FP), Lasers na semiconductor na Bragg Reflector (DBR), Lasers na semiconductor na waje (ECL), Lasers na semiconductor na ra'ayin ra'ayi (Laser DFB) , na'urorin laser na semiconductor cascade (QCL), da kuma na'urorin laser masu faɗi (BALD).

Tare da ƙaruwar buƙatar sadarwa ta gani, aikace-aikacen gano abubuwa ta 3D da sauran fannoni, buƙatar lasers na semiconductor yana ƙaruwa. Bugu da ƙari, lasers na semiconductor masu fitar da gefuna da lasers na semiconductor masu fitar da ramuka a tsaye suma suna taka rawa wajen cike gibin juna a aikace-aikacen da ke tasowa, kamar:
(1) A fannin sadarwa ta gani, ana amfani da EEL mai girman 1550 nm InGaAsP/InP (DFB laser) da EEL mai girman 1300 nm InGaAsP/InGaP Fabry Pero EEL a nisan watsawa na kilomita 2 zuwa 40 da kuma saurin watsawa har zuwa 40 Gbps. Duk da haka, a nisan watsawa na mita 60 zuwa 300 da kuma ƙarancin saurin watsawa, VCsels bisa ga InGaAs da AlGaAs mai girman 850 nm suna da rinjaye.
(2) Lasers masu fitar da saman ramin tsaye suna da fa'idodin ƙaramin girma da kuma kunkuntar tsawon rai, don haka an yi amfani da su sosai a kasuwar kayan lantarki na masu amfani, kuma haske da fa'idodin wutar lantarki na lasers masu fitar da gefen suna buɗe hanya don aikace-aikacen gano nesa da sarrafa wutar lantarki mai ƙarfi.
(3) Ana iya amfani da lasers na semiconductor masu fitar da gefen da kuma lasers na semiconductor masu fitar da saman rami a tsaye don gajere da matsakaici don cimma takamaiman aikace-aikace kamar gano tabo a makafi da kuma tashi daga layi.

5. Ci gaba a nan gaba
Laser ɗin semiconductor mai fitar da gefen yana da fa'idodin babban aminci, ƙarancin aiki da kuma yawan ƙarfin haske, kuma yana da fa'idodi masu yawa na amfani a fannin sadarwa ta gani, liDAR, likitanci da sauran fannoni. Duk da haka, duk da cewa tsarin kera lasers masu fitar da gefen ya kasance mai girma, domin biyan buƙatun kasuwannin masana'antu da masu amfani da shi don lasers masu fitar da gefen, ya zama dole a ci gaba da inganta fasaha, tsari, aiki da sauran fannoni na lasers masu fitar da gefen, gami da: rage yawan lahani a cikin wafer; Rage hanyoyin aiwatarwa; Haɓaka sabbin fasahohi don maye gurbin hanyoyin yanke ƙafafun niƙa da wafer na gargajiya waɗanda ke iya haifar da lahani; Inganta tsarin epitaxial don inganta ingancin laser mai fitar da gefen; Rage farashin masana'antu, da sauransu. Bugu da ƙari, saboda hasken fitarwa na laser mai fitar da gefen yana gefen gefen guntu na laser semiconductor, yana da wuya a cimma ƙaramin marufi na guntu, don haka har yanzu ana buƙatar ƙarin warware tsarin marufi mai alaƙa.
