Pfupiso yekudiwa kweDFB laser

Pfupiso yekudiwa kweLaser yeDFB
(1) Pfungwa huru ye DFB laser
DFB continuous laser, inozivikanwawo se continuous wave distributed feedbacklaser ye semiconductor, inobatanidza chimiro chegrating chinogara kwenguva refu munzvimbo inoshanda yelaser. Nekushandisa mhedzisiro yemhinduro yakagoverwa yegrating, frequency selective resonance inowanikwa, uye laser inoburitswa nenzira inoenderera mberi uye isina kukanganiswa mukati memaitiro ese, pasina kukanganiswa kwepulse kana kushanduka kwesimba.
Kana tichienzanisa nema FP lasers akajairwa nema pulsed DFB lasers, zvakanakira zvikuru zvayakanakira ndezvekuti: chekutanga, ine kugadzikana kwakasimba kwewavelength, inogona kuwana kuburitsa kwakaringana kwemutsara wakamanikana, uye inodzivirira zvakanyanya kudonha kwekushisa kwezvakatipoteredza uye kupindirana kwekudengenyeka; Chechipiri, simba rekuburitsa rinoenderera mberi uye rakagadzikana, rine hunhu hwenzvimbo yepamusoro uye ruzha rwakaderera zvakanyanya; Chechitatu, ine kubatana kwakanaka, bandwidth yakakura yekushandura, uye yakakodzera kune akasiyana ma optoelectronic scenes ane madaro marefu, kunyatsojeka, uye kugadzikana kwakanyanya. Zvichienderana nekusiyana kwehunhu, ma pulsed DFB lasers anowanzo shandiswa pakutaurirana kwe ranges uye pulse, nepo ma DFB continuous lasers achitarisa pane high-end steady-state application scenarios, ane zvipingamupinyi zvepamusoro zvehunyanzvi uye kukosha kwekuwedzera kwechigadzirwa.
（2） Ruzivo rwezvinodiwa neindasitiri
1. Kukurukurirana kwemaziso nekukurumidza kwakonzera kudiwa kukuru
Network yepasi rose yemagetsi emakombiyuta, nzvimbo dzemagetsi dze5G/6G, nzvimbo dzedata, uye network dzemusana dziri kuvandudzwa kusvika padanho repamusoro-soro re200G/400G/800G. Malaser echinyakare haakwanise kusangana nezvinodiwa zvekutumira kure uye kutadza kwakaderera. Malaser anoenderera mberi eDFB, senzvimbo huru yechiedza che high-speed optical modules, ndiwo matipi ekutanga ekushanda kwakasimba kwemasisitimu ekukurukurirana e high-speed optical.
2. Kutsiviwa kwemasensa emhando yepamusoro muChina kuri kudiwa nekukurumidza
Minda ye fiber optic sensing, gas detection, LiDAR, petroleum exploration, aerospace precision detection, nezvimwewo ine zvinodiwa zvakasimba zve wavelength accuracy, stability, uye service lifetime yechiedza chelaserKwenguva yakareba, ma-laser eDFB anoramba achishandiswa zvakanyanya ave achivimba nekutenga zvinhu zvinotengeswa kunze kwenyika, uye kudiwa kwemuno kwekutonga kwakazvimirira kuri kuramba kuchiwedzera, zvichimanikidza budiriro yetekinoroji muchikamu cheindasitiri.
3. Kuramba kuchiwedzera mamiriro ekushandisa ari kubuda
Minda iri kusimuka yakadai sekurapa nelaser, kuongorora kwakanyatsojeka kwespectral, kuona tembiricha isingachinji yeindasitiri, uye kutaurirana kwequantum zviri kukura nekukurumidza. Matsime emwenje elaser asingachinji, ruzha rushoma, uye mwenje wakamanikana welaser unochinjika zvave zvakajairika munzvimbo iyi, zvichiramba zvichivhura nzvimbo inowedzera muindasitiri.
