Kushanda kwehunyanzvi kweSemiconductor Laser

Kushanda kwechokwadi kwesemiconductor laser

Chekutanga pane zvese, izvo paramende zvinodiwa zveSemiconductor Lasers vanounzwa, kunyanya kusanganisira zvinotevera zvinhu:
1.
2. Saizi reruvara: senge luminous size uye kurongeka, kubviswa kwekupedzisira tsanangudzo, saizi yekuisa uye saizi yehurukuro.
3.
4.
5. Simba uye voltage: Nekuyera simba, voltage uye zvazvino zveSemiconductor Laser pabasa, PV, PI uye iv, Pi Curves inogona kukwezva kuti vanzwisise maitiro avo ekushanda.

Basa rekushanda
1. Wana mamiriro ezvinhu: Iyo inversion kugovera kwekutakura vatakuri mukurasikirwa kwepakati (nharaunda inoshanda) inosimbiswa. MuSemiconductor, simba remagetsi rinomiririrwa nenhevedzano yeanenge achienderera mberi emagetsi mazinga. Naizvozvo, huwandu hwemagetsi pazasi peiyo Bhokisi bhendi mune yakakwira simba mamiriro anofanirwa kunge akakura kwazvo kupfuura huwandu hwemabhandi mune yakaderera simba mamiriro ezvikamu zviviri kuti uwane iyo inversion yenhamba yeiyo nhamba yeiyo nhamba yeiyo nhamba yeiyo nhamba yehuwandu hwenhamba. Izvi zvinowanikwa nekushandisa zvisina kunaka kusarudzika kune homojunction kana kujekesa vatakuri vanodiwa kuti vatevedzere veganda rekunakisa kubva kuSeal Energy Valence Band kune yakakwira simba rebhandi. Kana huwandu hukuru hwemagetsi mune dzidzo dzakatenderwa huwandu hwehuwandu hweHurumende nehombodo, dzakakurudzirwa emission inoitika.
2. Kuti vanyatso kuwana madhimoni akadzika, radiation yakakwenenzverwa inoumbwa neyekupedzisira Kune iyo FP Cavity (Fabry-Perot Cavity) Semiconductor Laser, iyo FP Cavity Inogona kuvakwa nyore nyore nekushandisa ndege yemusango pnpendicular kune iyo PN Junction ndege yekristaro.
(3. Izvi zvinofanirwa kuve neine yakasimba iripo jekiseni, ndiko kuti, pane yakakwana nhamba yenhamba yekutsamwa, iyo yakakwira mwero wehuwandu hwekutsamwa, iyo inowedzera kuwana, ndiko kuti, izvo zvinodikanwa zvinofanirwa kusangana neimwe chikumbaridzo. Kana iyo Laser inosvika chikumbaridzo, chiedza neyakasarudzika wavelength inogona kuiswa mumarara uye yakakwidziridzwa, uye pakupedzisira gadzira laser uye inoenderera mberi.

Performance zvinodiwa
1. Modulation Bandwidth uye chiyero: Semiconductor Lasers uye tekinoroji yavo inokosha mukukurukurirana kwechinhu chisina waya, uye bandwidt Yemukati Yakatemwa Laser (yakananga yakadudzirwa laser) Inokodzera minda dzakasiyana siyana mune Optical fiber kutaurirana nekuda kwekukurumidza kwekukurumidza kutumira uye mutengo wakaderera.
2..Dfb laser) vava sosi yakakosha yechiedza muOptical fiber kutaurirana uye nzvimbo yekukurukurirana kwekutaurirana nekuda kwehunhu hwavo hunokwanirisa uye hunhu hwezvinhu.
3. Mutengo uye kugadzirwa kwakawanda: Semiconductor Lasers inoda kuve nezvakanakira kuti zvibodzwa zvakaderera uye kugadzirwa kwakawanda kusangana nezvinodiwa mukugadzirwa kwakakura uye kushandiswa.
4. Simba Kuwedzerwa uye Kuvimbika: Mune zviitiko zvekushandisa senge matanho e data, Semiconductor Lasers inoda kuderera simba uye kuvimbika kwakareba kwekushanda kwenguva refu.
