Chii chinonzi asemiconductor optical amplifier
A semiconductor optical amplifier imhando ye optical amplifier inoshandisa semiconductor kuwana yepakati. Iyo yakafanana nelaser diode, umo girazi riri pamucheto wezasi rinotsiviwa nehafu-reflective coating. Chiedza chechiratidzo chinofambiswa kuburikidza ne semiconductor single-mode waveguide. Iyo yakachinjika dimension ye waveguide ndeye 1-2 micrometer uye kureba kwayo kuri pahurongwa hwe0.5-2mm. Iyo waveguide mode ine yakakosha kupindirana neiyo inoshanda (amplification) dunhu, iyo inopombwa neizvino. Ikozvino jekiseni inogadzira imwe yekutakura mutakuri mubhendi yekuitisa, ichibvumira shanduko yekuona yebhendi rekufambisa kune valence bhendi. Kuwana kwepamusoro kunoitika kana iyo photon simba iri shoma pane iyo bandgap simba. SOA Optical amplifier inowanzo shandiswa mumasevhisi ekufonera muchimiro chepigtails, ine yekushanda wavelength yakatenderedza 1300nm kana 1500nm, ichipa ingangoita 30dB yekuwana.
TheSOA semiconductor Optical amplifieriPN junction mudziyo une strain quantum tsime chimiro. Iyo yekunze yekumberi bias inodzosera kumashure nhamba ye dielectric particles. Mushure mekunge chiedza chekunze chekunze chapinda, mhepo inokurudzirwa inogadzirwa, ichiwana kukwidziridzwa kwezviratidzo zvemaziso. Ese matatu ari pamusoro ekufambisa simba maitiro aripo mukatiSOA Optical amplifier. Kukwidziridzwa kwezviratidzo zvemaziso kunobva pakusimudzirwa kwekubuda. Iyo inokurudzirwa yekunyura uye inokurudzirwa emission maitiro aripo panguva imwe chete. Kunyudzwa kwechiedza chepombi kunogona kushandiswa kukurumidzira kupora kwevatakuri, uye panguva imwe chete, pombi yemagetsi inogona kutumira maerekitironi kune yakakwirira simba (conduction band). Kana mwaranzi inongoerekana yawedzerwa, inozogadzira ruzha rwemwaranzi rwakasimudzwa. SOA Optical amplifier yakavakirwa pane semiconductor machipisi.
Semiconductor machipisi anoumbwa necompound semiconductors, akadai seGaAs/AlGaAs, InP/AlGaAs, InP/InGaAsP uye InP/InAlGaAs, nezvimwewo. Izvi zvakare zvinhu zvekugadzira semiconductor lasers. Iyo waveguide dhizaini yeSOA yakafanana kana yakafanana neye lasers. Musiyano uri pakuti ma lasers anofanirwa kuumba resonant mhango yakatenderedza yekuwana yepakati kugadzira uye kuchengetedza oscillation yechiratidzo chemaziso. Chiratidzo chemaziso chichawedzerwa kakawanda mugomba risati rabuda. InSOA amplifier(zvatiri kukurukura pano zvinongogumira kune anofamba mafungu amplifiers anoshandiswa mune akawanda maapplication), mwenje unongoda kupfuura nepakati pekuwana kamwe chete, uye kutarisisa kumashure kudiki. Iyo SOA amplifier structure ine nzvimbo nhatu: Nharaunda P, Nzvimbo I (inoshanda mutsara kana node), uye Nharaunda N. Iro rinoshanda rinowanzoumbwa ne quantum Wells, iyo inogona kuvandudza photoelectric kushanduka kwekugadzirisa uye kuderedza chikumbaridzo chezvino.
Mufananidzo 1 Fiber laser ine yakabatanidzwa SOA yekugadzira optical pulses
Inoshandiswa pakufambisa chiteshi
SOAs kazhinji haingoshandiswi pakukwidziridzwa chete: inogona zvakare kushandiswa mumunda we optical fiber kutaurirana, zvikumbiro zvinoenderana neasina mutsara maitiro senge saturation kuwana kana kuyambuka-phase polarization, iyo inoshandisa kusiyanisa kwemutakuri concentration muSOA optical amplifier kuti uwane akasiyana efractive indices. Izvi zvinogona kushandiswa kune chiteshi chekufambisa (wavelength kutendeuka), modulation format conversion, clock recovery, signal regeneration uye maitiro ekuzivikanwa, nezvimwewo mu wavelength division multiplexing systems.
Nekufambira mberi kwe optoelectronic integrated circuit tekinoroji uye kudzikiswa kwemitengo yekugadzira, iyo minda yekushandisa yeSOA semiconductor optical amplifier seyakakosha amplifiers, inoshanda optical zvishandiso uye subsystem zvikamu zvicharamba zvichikura.
