Electrically driven single microwire-based single-mode microlaser
文献摘要：
Engineering the lasing-mode oscillations effectively within a laser cavity is a relatively updated attentive study and perplexing issue in the field of laser physics and applications.Herein,we report a realization of electrically driven single-mode microlaser,which is composed of gallium incorporated zinc oxide microwire(ZnO:Ga MW)with platinum nanoparticles(PtNPs,d～130 nm)covering,a magnesium oxide(MgO)nanofilm,a Pt nanofilm,and a p-type GaN substrate.The laser cavity modes could resonate following the whispering-gallery mode(WGM)among the six side surfaces by total internal reflection,and the single-mode lasing wavelength is centered at 390.5 nm with a linewidth of about 0.18 nm.The cavity quality factor Q is evaluated to about 2169.In the laser structure,the usage of Pt and MgO buffer layers can be utilized to engineer the band alignment of ZnO∶Ga/GaN heterojunction,optimize the p-n junction quality and increase the current injection.Thus,the well-designed device structure can seamlessly unite the electron-hole recombination region,the gain medium,and optical microresonator into the PtNPs@ZnO∶Ga wire perfectly.Such a single MW microlaser is essentially single-mode regardless of the gain spectral bandwidth.To study the single-mode operation,PtNPs working as superabsorber can engineering the multimode lasing actions of ZnO∶Ga MWs even if their dimensions are typically much larger than that of lasing wavelength.Our findings can provide a straightforward and effective scheme to develop single-mode microlaser devices based on one-dimensional wire semiconductors.
