Muminda yenanophooticuye biomonyicine, microdisklasersuye nanodisk lasers ave kuvimbisaZvigadzirwa zvechiedzauye probes. Muzviitiko zvakati wandei senge pa-chip Photonic kutaurirana, Biochemical Sensing, uye Quixum Phooter Ruzivo rwekugadzirisa Nekudaro, zvinoramba zvichinetsa kugadzirwa microdisk uye naneDisk lasers yeiyi chaiyo wave wave pane yakakura. Parizvino Nanefabrication Processes inosuma kusagadzikana kwe disc diamita, iyo inoita kuti zviome kuwana set waveOptoelectronic mushongaYakagadzira optochemical optochemical (pec) etching maitiro ayo anobatsira kunyatso tune iyo laser wavelength ye microdisk laser ine subnanometer chaiyo. Basa racho rinobudiswa muJernal advanced pototics.

Photchemical Etching
Sekureva kwemishumo, iyo nzira itsva yemusangano inogonesa kugadzirwa kweiyo micro-disk lasers uye nanedisk laser arrays neyechokwadi, yakafanorongerwa emendesion. Iyo kiyi yeiyi breakther ndeyekushandisa kwePEC etching, iyo inopa nzira inoshanda uye inokatyamadza yekuyevedza-tune iyo wavelength yeiyo microdisc laver laver laser laver. Mhedzisiro iri pamusoro, timu yakabudirira kuwana indium Gallium Arsenide phazhating microdisks yakafukidzwa neSilica pane indium phosphesi column chimiro. Ivo vakabva vatora laser wavelength yeiyi microdisks chaizvo kune kukosha kwakatemwa nekuita Photochemical etching mumhinduro yakadzvanywa yeSulfutic acid.
Vakaongororawo michina uye masimba emhando yeiyo chaiyo Photochemical (pec). Pakupedzisira, vakatamisa microducth-tuned microdisk array pane polydimethssihLysixane kuti vabudise yakazvimirira, vakasarudzika laser zvimedu zvakasiyana. Iyo microdisk inokonzeresa inoratidza ultra-wideband bandwidth yeLaser emission, nelaserpane iyo kirabhu isingasviki 0.6 nm uye iyo yakazvimiririra isingasviki 1.5 nm.

Kuvhura musuwo kune biomedical application
Mhedzisiro iyi inovhura musuwo kune akawanda matsva nanophotonics uye biomedical apportations. Semuenzaniso, kumira-oga microdisk lasers vanogona kushandira seyengoro-yedhishi yemhando dzechisimba, dzakadai sedzakarukwa. Nekudaro, mashoma mashoma marudzi echitokisi anogona kunyorwa panguva imwe chete. Kusiyana neizvi
Chikwata chakaedzwa uye chakabudirira kuratidzwa zvakanyatsonaka microdisk laser zvidimbu sevhu biommarkers, vachishandisa iyo yekurayiridzira yakajairika emazamu epithelial masero mcf10a. Nepo yavo Ultra-wideband Iyo tekinoroji yakavakirwa paPEC ECCHING inoratidza yakakura kufambira mberi mu microdisk lasers. Scalingafulation yenzira, pamwe neyenyanzvi yayo subnanometer
