Mafambiro ebudiriro yelaser yakamanikana ine upamhi hwemutsara
Kushanduka kwemaitiro emhinduro yelaser mulaser ine upamhi hwemutsara wakamanikana ndiko kushanduka kwechimiro chelaser resonant cavity. Pazasi, tichatsanangura marongero akasiyana-siyana ematekinoroji elaser ane upamhi hwakamanikana zvichienderana nekushanduka kwelaser resonators.
1. Kurongeka kwegomba guru rimwe chete. Rudzi urwu rwelaser runogona kukamurwa kuita gomba rakatsetseka (kurongeka kwekare, chimiro chiri nyore uye chinoshanda) uye gomba rakatenderedzwa (kukunda kupisa kwegomba renzvimbo uye kushandisa nzvimbo yemafungu ekufamba). Non planar ring resonator (NPRO) inotaurwa zvakananga mu ring resonator, inova nzvimbo yemafungu ekufamba yakasarudzika uye yakasimba kwazvo.laserKubva pamaonero ehurefu hwegomba, rinogona kukamurwa kuita makomba mapfupi (ari nyore kushandisa single longitudinal mode SLM, asi nehupamhi hwemutsara wemukati wakafara uye ruzha rwakanyanya) uye makomba marefu (zvachoseupamhi hwemutsetse wakamanikana, asi kuita mashandiro eSLM idambudziko rehunyanzvi).
2. Kugadziriswa kwemhinduro yekunze kwemugodhi mumwe chete. Kugadziriswa uku kunokurudzirwa kugadzirisa matambudziko enguva pfupi yekudyidzana kwephoton uye kuoma kwekubvisa kubuda kwega kwega mugodhi guru rimwe chete, nekusefa nekudzosera maphoton kuburikidza negodhi rekunze kuti vamanikidze upamhi hwemutsara. Zvimiro zvekare zvaisanganisira magodhi ekunze emhando yeLittrow naLittman Metcalf vachishandisa magirati. Dambudziko rehunyanzvi rekugadzirisa uku riri mukufananidza phase pakati pegodhi guru negodhi rekunze.
3. Magadzirirwo maviri makuru emukati akabatanidzwa akavakirwa paBragg gratings:
Laser yeDFBconfiguration: Kusanganisa Bragg structure nenzvimbo inoshanda uye kuisa phase shift region, ine integration yakakura, kugadzikana uye kushanda, uye inovandudza wavelength drift yeDBR. Dambudziko rehunyanzvi riri mukugadzirisa grating (senge secondary epitaxial RGF-DFB uye surface etching SG-DFB methods dze semiconductor DFB).
Kugadziriswa kwelaser yeDBR: inotsiva magirazi echinyakare nemagadzirirwo eBragg asingashande nguva nenguva, ane hunhu hwekusefa uye ari nyore kushandisa SLM ine maburi mapfupi. Zvichienderana negain medium, inogona kukamurwa kuita semiconductor DBR (ine process compatibility yakanaka) uye fiber DBR (zvichienderana nefiber processing uye doping technology).
Kuti tiwedzere kudzvanya hupamhi hwemutsara wegomba guru repaburi pfupi (senge DFB/DBR), chimiro chegomba rekunze chakabatanidzwa chichashandiswa. Chimiro chegomba rekunze chakashanduka nekuvandudzwa kwetekinoroji:
Nzvimbo yekunze: mafomu makuru ekutanga, anosanganisira grating (Littrow/Littman) uye mafirita akasiyana-siyana e optical (akadai seFP standard).
Fiber optic external cavity: uchishandisa zvese zvishandiso zve fiber optic (senge fiber optic circuits, FBGs, fiber optic FP cavities, nezvimwewo), kubatanidzwa uye kugona kudzivirira kukanganiswa kwakasimba.
Kunze kwewaveguide cavity: Kugadziriswa kwe micro nano kwakavakirwa pazvinhu zve semiconductor zvakaita seSi neSi3N4, zvichiita kuti system ive diki uye yakagadzikana.
Pakupedzisira, chinyorwa chino chinosuma magadzirirwo ema lasers e optoelectronic oscillating, inova nzira yakakosha yekupa mhinduro, senge tekinoroji yePDH frequency stabilization. Nekushandisa mhinduro yemagetsi isina kunaka kuvharira frequency ye laser kune sosi yekutarisa yakasimba, kugadzikana kwema frequency kwakanyanya kunogona kuwanikwa. Zvisinei, sisitimu yacho yakaoma, inodhura, uye kuchinjika kwema wavelength kwakaganhurirwa.
