4. Matsayin aikace-aikacen na'urar laser semiconductor na gefuna
Saboda faffadan nisan zangonsa da babban iko, an yi nasarar amfani da na'urar laser semiconductor a fannoni da yawa kamar na mota, sadarwa ta gani da kumaLasermagani. A cewar Yole Developpement, wata mashahuriyar hukumar bincike ta kasuwa ta duniya, kasuwar Laser-gefen-emit za ta yi girma zuwa dala biliyan 7.4 a cikin 2027, tare da haɓaka haɓakar shekara-shekara na 13%. Wannan ci gaban zai ci gaba da gudana ta hanyar sadarwa na gani, kamar na'urori masu gani, amplifiers, da aikace-aikacen ji na 3D don sadarwar bayanai da sadarwa. Don buƙatun aikace-aikacen daban-daban, an haɓaka tsarin ƙirar EEL daban-daban a cikin masana'antar, gami da: Fabripero (FP) laser semiconductor lasers, Rarraba Bragg Reflector (DBR), Laser cavity na waje (ECL) laser semiconductor lasers, rarraba ra'ayi semiconductor lasers (Farashin DFB, Quantum Cascade semiconductor Laser (QCL), da kuma faffadan Laser diodes (BALD).

Tare da karuwar buƙatar sadarwar gani, aikace-aikacen ji na 3D da sauran fagage, buƙatun laser na semiconductor shima yana ƙaruwa. Bugu da kari, na'urorin da ke fitar da na'ura mai kwakwalwa da na'ura mai daukar hoto a tsaye suma suna taka rawa wajen cike kasawar juna a aikace-aikace masu tasowa, kamar:
