Kutambisa nheyo yeTunable semiconductor laser (tunable laser)

Tuning nheyo yeTunable semicononductor laser(Tunable laser)

Tunable Semiconductor Laser rudzi rwe laser iyo inogona kuramba ichichinja iyo wavelength ye laser inobuda mune imwe huwandu. Sunable Semiconductor Laser anotora kuora kuronga, magetsi ekutonga uye mhepo tuning kuti gadzirise kureba, grating kuratidzira spectrum, chikamu uye zvimwe zvinoshanduka kuti uwane wavelength tuning. Rudzi urwu rwe laser ine huwandu hwakawanda hwekushandisa mukukurukurirana kwepfungwa, spectroscopy, kunzwa, kurapwa uye mamwe minda. Mufananidzo 1 unoratidza kuumbwa kwekutanga kwe atunable laser, kusanganisira iyo mwenje uwane unit, iyo FP cavity inoumbwa nepamberi uye kumashure magirazi, uye iyo Optical Mode Sarudzo yechisimba faira. Pakupedzisira, nekugadzirisa urefu hwechiratidzo checlection, iyo Optical Mode faira inogona kusvika iyo wavelength section kubuda.

Nzira yekuita uye kubviswa kwayo

Nheyo yekudonha ye tunablesemiconductor lasersKunyanya zvinoenderana nekuchinja maratidziro epanyama eiyo laser resonator kuti ienderane nekuchinja kwekuenderera kana discrete kuchinjika mune iyo yekubuda laser wavelength. Iyi paramita inosanganisira, asi haina kungogumira, iyo index index, kureba kwekureba, uye kusarudzwa kwemo. Izvi zvinotevera zvinyorwa zvinowanzoitika nzira dzekutonga uye nheyo dzadzo:

1. Kutakura jekiseni kuridza

Kutakurisa jekiseni kuraswa index yekudzora kwezvinhu nekuchinja iyo yazvino kuiswa munzvimbo inoshanda yeiyo Semiconductor Laser, kuitira kuti uwane wavelength tuning. Kana iko kwazvino kuchiwedzera, kutakura kwekutakura munzvimbo inoshanda inowedzera, zvichikonzera shanduko muRextive Index, iyo inoshanduka inokanganisa laser wavelength.

2.. Shanduko mukudziya inokanganisa iyo indekisi yekudzora uye kukura kwemuviri kwechinyorwa.

3. Mechancal tuning mechanical tuning ndeyekuzadzisa wavelength tuning nekuchinja chinzvimbo kana angle yezvinyorwa zvekunze zveiyo laser. Zvakajairika michina ekutonga nzira dzinobatanidza nzira dzinosanganisira kuchinja kona yeiyo digraction yakarongedzwa uye inofambisa chinzvimbo chegirazi.

4 Electro-Optical Kuronga Electro-Optical Tuning inowanikwa nekushandisa munda wemagetsi kuenda kuMemiconductor Chinyorwa chekuchinja index yezvinyorwa, nekudaro anowana wavelength tuning. Iyi nzira inowanzo shandiswa mukatiElectro-Optical Modulators (Eom) uye electro-yakapamhama lasers lasers.

Mukupfupikisa, nheyo inosimbisa yeTunable Semiconductor Laser inonyanya kuongorora wavelength nekuchinja maratidziro epanyama emugadziri. Iyi parameter inosanganisira index yekudzora, kureba kweguva, uye kusarudzwa kwemo. Nzira dzechokwadi dzechiitiko dzinosanganisira kutakura jekiseni kuridza mhere, kupinza tuning, mechanic tuning uye Electro-Optical tuning. Nzira imwe neimwe ine chaiyo chaiyo yemuviri uye masvomhu emasvomhu, uye kusarudzwa kweiyo nzira yakakodzera yekubata inoda kufungidzirwa zvichienderana nezvinodiwa zvekushandisa, zvakadai sekumhanyisa, kugadzirisa uye kugadziriswa uye kugadzikana uye kugadzikana.
