Zvaunofanira kufunga nezvekugadziralaser ine simba guru re semiconductor
Chinyorwa chino chichanyatsotsanangura zvakarongeka nezvekufunga nezvekugadzira uye nzira dzekushandisa semiconductor ine simba guru.laserZvichibva pane pfungwa huru yekuti "kuwedzera muganho wepamusoro wesimba nekuwedzera huwandu hwechiedza, kugadzirisa nzira dzekushandura simba uye nzira dzekuparadza uku uchidzivirira kukuvara kwemaziso kwakakomba (COD)", ongororo yakadzama yakaitwa kubva pazvinhu zvipfumbamwe zvakakosha:
1. Nzvimbo yakafara yekuburitsa mweya: Nekushandisa chimiro chenzvimbo yakakura (sekuwedzera upamhi hwenzvimbo yekuburitsa mweya W kubva pama micrometer mashoma kusvika pama micrometer 50-200), simba guru rekuburitsa mweya rinogona kuwedzerwa zvakananga, inova ndiyo nzira huru yekuwana kubuda kwechubhu imwe chete padanho rewatt kana kunyange makumi ema watts, asi zvinoderedza kunaka kwemwaranzi.
2. Kureba kwenzvimbo: Kuwedzera kureba kwenzvimbo ndiyo kiyi yekuvandudza mashandiro emagetsi ekupisa uye kuwana mashandiro anoshanda nesimba rakawanda. Chinhu chikuru chayo chiri mukuderedza zvinobudirira kuramba kupisa uye kuramba kwemudziyo, nokudaro ichidzvinyirira kukwira kwekupisa kwenzvimbo inoshanda, kuderedza mhedzisiro yesimba, uye kuvandudza simba rinobuda uye kushanda zvakanaka.
3. Kupamhama kwemafungu uye maburi emaziso asina kuenzana: Nekuwedzera kugoverwa kwenzvimbo dzemagetsi (sekushandisa zvivakwa zvemagetsi zvisina kuenzana), kupindirana pakati penzvimbo dzemagetsi nenzvimbo dzinodonhedza mvura zvakanyanya kunogona kuderedzwa, zvichideredza zvakanyanya kurasikirwa kwemukati, kuvandudza kushanda kwequantum, uye kuderedza kugadzirwa kwekupisa. Panguva imwe chete, hunhu hwemwenje munzira yakatwasuka hunogonawo kuvandudzwa.
4. Chinozadza: Mumidziyo yebhawa, chinhu chinozadza (chiyero chehupamhi hwese hweyuniti inoburitsa chiedza nehupamhi hwese hwebhawa) ndicho chinhu chikuru chinoratidza kuenzana kwesimba rinobuda uye kuoma kwekutonga kupisa. Chinhu chinozadza zvakanyanya chinounza huwandu hwesimba rakawanda asi chinoda kupisa kwakanyanya, nepo chinhu chinozadza zvishoma chinobatsira zvikuru pakutonga kupisa uye chinovandudza kuvimbika.
6. Tekinoroji yekudzivirira kumeso: Kuvandudza muganhu wekukuvara kwegirazi remaziso (COMD) pamucheto wekumusoro ndiyo kiyi yekubuda mudambudziko remagetsi. Nyaya iyi inotsanangura matekinoroji matatu makuru:
6.1 Kunyungudutsa uye kuputira pamusoro pegomba: Nekuisa ma layers ekudzivirira uye kuputira mafirimu ekudzivirira kuratidzira zvakanyanya/anodzivirira kuratidzira, zvikanganiso zvepakona zvinonyungudutsa, kusanganiswa kwenon radiative kunodziviswa, uye chiyero cheCOMD chinovandudzwa zvakanyanya.
6.2 Tekinoroji yewindo risinganyudzi: Kushandisa quantum well hybridization nedzimwe nzira dzekugadzira nzvimbo yehwindo yakajeka kumucheto wekupedzisira kuderedza kunyudzwa kwechiedza uye kudzivirira COMD.
6.3 Tekinoroji yenzvimbo isina jekiseni pamusoro penzvimbo ine jekiseni: Isa nzvimbo isina jekiseni iri pedyo nepamusoro penzvimbo ine jekiseni kuti uderedze huwandu hwemutakuri uye kudzokororwa kwenzvimbo isina radiation pamusoro penzvimbo ine jekiseni.
7. Dhizaini yekupenya kwakanyanya: Nzira mbiri dzekuwana kupenya kwakanyanya dzinounzwa kugadzirisa dambudziko remhando isina kunaka yemwaranzi mu laser iri munzvimbo yakakura:
7.1. Maumbirwo ekoni: Kubatanidza "nzvimbo yembeu" ine waveguide iri kumberi uye "nzvimbo yekuwedzera cone" iri kumberi, kunaka kwedanda riri pedyo nemuganhu wekupararira kunochengetwa uku simba richiwedzerwa.
7.2 Kudzora Modhi: Kuunza ma microstructures ari munzvimbo dzakasiyana-siyana kuti zviwedzere kurasikirwa kwe higher-order transverse modes, nokudaro zvichivandudza kunaka kwe beam.
8. Kudzvanya kwequantum well uye kudzvanya kwestrain: Kuunza kudzvanya munzvimbo inoshanda yequantum well kunogona kugadzirisa chimiro chebhendi, kuwedzera gain differential, nokudaro kuderedza threshold current, kuvandudza kushanda, uye kuwedzera hunhu hwekupisa kwakanyanya. Tekinoroji yekudzvanya strain inodzivirira kuungana kwestrain uye zvikanganiso nekukura ma barrier layers ane reverse strain, zvichiita kuti zvinhu zvive zvakanaka.
9. Kutarisira kupisa kwepamusoro uye kurongedza kushoma: Mukupindura matambudziko ekupisa anokonzerwa nekuwanda kwesimba, chinyorwa chino chinoburitsa zvinhu zvitsva zvekupisa (zvakaita semadhaimani akabatanidzwa), ma microchannel coolers, uye matekinoroji ekupakata achishandisa zvinhu zve low stress interface kuti zviwane kugona kupisa kwakanyanya uye kuvandudza kuvimbika.
10. Distributed waveguide: Senzira yekutonga kupisa kwemukati mechip level, chimiro ichi chinopatsanura ridge waveguide kuita nzvimbo yekukurudzira uye nzvimbo yekupisa isingapindike pamwe chete nehurefu hwegomba, uye inovaka nzira yekupisa inochinjika mukati mechip kuti ibvise kupisa zvinobudirira, ichipfuura nepakati pemiganhu yenzira dzechinyakare dzekubvisa kupisa.
Pfupiso nemaonero zvinoratidza kuti dhizaini yemagetsi ane simba gurulaser ye semiconductoridambudziko rekugadzirisa zvinhu rine chinangwa chakawanda rinosanganisira magetsi, optics, thermodynamics, uye kuvimbika. Zvakakosha kuti pave nekuenzana kwakanakisa pakati pemagadzirirwo matatu ekutanga enzvimbo yakafara yekuburitsa mhepo, nzvimbo refu, uye waveguide yakafara, uye matekinoroji anotarisana nematambudziko matatu makuru ekutarisira kupisa, kukuvara kwechiso chekupedzisira, uye mhando yemwaranzi. Kuvandudzwa kwakawedzerwa kwekushanda mune ramangwana kuchaenderana nekugadzirwa kwezvinhu zvitsva, nzira itsva dzemuviri, uye maitiro matsva ekugadzira.
