Microcavity yakaoma lasers kubva kune yakarongedzerwa kuenda kune isina kurongeka nyika

Yakajairwa laser ine zvinhu zvitatu zvakakosha: pombi sosi, svikiro rekuwana iro rinokwidziridza mwaranzi inokurudzirwa, uye chimiro chegomba chinoburitsa resonance yemaziso. Kana iyo mhango saizi yelaseriri padyo neiyo micron kana submicron level, yave imwe yeazvino tsvagiridzo hotspots munharaunda yevadzidzi: microcavity lasers, iyo inogona kuwana yakakosha mwenje uye nyaya kupindirana mune vhoriyamu diki. Kubatanidza ma microcavities neakaomesesa masisitimu, senge kuunza zvisingaite kana kusagadzikana muganho, kana kuunza yakaoma kana isina kurongeka inoshanda midhiya mumamicrocavities, ichawedzera chiyero cherusununguko rwekubuda kwelaser. Iwo emuviri asiri-cloning maitiro eakavhiringidzika cavities anounza multidimensional kudzora nzira dzelaser paramita, uye inogona kuwedzera kugona kwayo kwekushandisa.

Masisitimu akasiyana siyanamicrocavity lasers
Mune iri bepa, zvisingaite microcavity lasers akaiswa kubva kwakasiyana mhango zviyero kekutanga. Musiyano uyu haungoratidzi chete yakasarudzika yekubuda hunhu hweiyo random microcavity laser mune akasiyana mativi, asi zvakare inojekesa zvakanakira saizi mutsauko weiyo random microcavity munzvimbo dzakasiyana-siyana dzekutonga uye dzekushandisa. Iyo yetatu-dimensional solid-state microcavity kazhinji ine diki modhi vhoriyamu, nekudaro inowana rakasimba mwenje uye nyaya kudyidzana. Nekuda kweiyo matatu-dimensional yakavharwa chimiro, iyo mwenje mwenje inogona kuve yakanyanya kugariswa munzvimbo nhatu, kazhinji ine yemhando yepamusoro chinhu (Q-factor). Aya maitiro anoita kuti ive yakakodzera kune yakakwirira-chaiyo sensing, photon chengetedzo, quantum ruzivo rwekugadzirisa uye mamwe epamusoro tekinoroji minda. Iyo yakavhurika maviri-dimensional yakaonda firimu system ipuratifomu yakanakira yekuvaka isina kurongeka planar zvimiro. Seyaviri-dimensional yakakanganiswa dielectric ndege ine yakabatanidzwa kuwana uye kuparadzira, iyo yakaonda firimu system inogona kushingaira kutora chikamu muchizvarwa cherando laser. Iyo planar waveguide effect inoita kuti laser coupling uye kuunganidza zvive nyore. Iine chiyero chegoviti chichiwedzera kuderedzwa, kubatanidzwa kwemhinduro uye kuwana midhiya mune imwe-dimensional waveguide inogona kudzvanya radial mwenje kupararira uku uchiwedzera axial mwenje resonance uye kubatana. Iyi nzira yekubatanidza pakupedzisira inovandudza kushanda kwelaser chizvarwa uye kubatanidza.

Kudzora maitiro easina kurongeka microcavity lasers
Zvizhinji zvinongedzo zvechinyakare lasers, senge kuwirirana, chikumbaridzo, nzira yekubuda uye polarization maitiro, ndiwo akakosha maitiro ekuyera kubuda kwe lasers. Kuenzaniswa neyakajairwa lasers ine yakagadziriswa symmetric cavities, iyo random microcavity laser inopa kushanduka kwakawanda muparameter regulation, iyo inoratidzwa mumiyero yakawanda inosanganisira nguva domain, spectral domain uye spatial domain, ichiratidza iyo yakawanda-dimensional controllability yerandom microcavity laser.

Maitiro ekushandisa easina kurongeka microcavity lasers
Kudzika kwepakati pekubatana, mode randomness uye kunzwa kune zvakatipoteredza zvinopa zvakawanda zvakanaka zvinhu zvekushandiswa kwe stochastic microcavity lasers. Iine mhinduro yekudzora modhi uye kutungamira kudzora kweasina kurongeka laser, iyi yakasarudzika mwenje sosi iri kuwedzera kushandiswa mukufungidzira, kuongororwa kwekurapa, kunzwa, kutaurirana ruzivo uye mamwe minda.
Seyakanganisirwa micro-cavity laser pamicro uye nano scale, iyo random microcavity laser inotarisana nekuchinja kwezvakatipoteredza, uye maitiro ayo eparametric anogona kupindura kune zvakasiyana-siyana zviratidzo zvinotarisa mamiriro ekunze, zvakadai sekushisa, humidity, pH, fluid concentration, refractive index, nezvimwewo, kugadzira chikuva chepamusoro chekuziva maapplication ekunzwa akanyanya. Mundima yekufungidzira, iyo yakanakalight sourceinofanira kunge iine high spectral density, yakasimba yekubuda kwegwara uye yakaderera spatial coherence kudzivirira kukanganisa kunokanganisa mhedzisiro. Vatsvakurudzi vakaratidza zvakanakira ma lasers emahara ekufungidzira emahara mu perovskite, biofilm, liquid crystal scatterers uye cell tissue carriers. Mukuongororwa kwechiremba, random microcavity laser inogona kutakura ruzivo rwakapararira kubva kune biological host, uye yakashandiswa zvakabudirira kuti ione akasiyana biological tishu, izvo zvinopa nyore kune kusiri-invasive kuongororwa kwekurapa.

Mune ramangwana, kuongororwa kwakarongeka kweakakanganisika microcavity zvimiro uye yakaoma laser chizvarwa masisitimu anozove akazara. Nekuenderera mberi kwekuenderera mberi kwesainzi yemidziyo uye nanotechnology, zvinotarisirwa kuti zvimwe zvakanaka uye zvinoshanda zvisina kurongeka microcavity zvimiro zvichagadzirwa, izvo zvine mukana mukuru mukusimudzira tsvakiridzo yekutanga uye inoshanda mashandisiro.
