Herein, the optically induced operation of ZnO‐based laser structures is reported, fabricated with plasma‐assisted molecular beam epitaxy (PA‐MBE) on native ZnO substrate. ZnMgO is used both to confine the optical mode within ZnO waveguide and to form quantum barriers of ZnO quantum wells. The resonator of these devices is defined by reactive ion etching (RIE) with a chlorine/argon plasma. The lowest laser threshold is measured to be approximately 0.4 MW cm−2 at room temperature when excited via the third harmonic of a YAG:Nd (355 nm). It is observed that the mode spacing depends on both the resonator length and the excitation power density, which is explained by introducing plasmonic corrections to the waveguide refractive index.

“…To achieve electrically pumped random lasers, p-Mg 0.35 Zn 0.65 O∕n-ZnO core-shell nanowire heterostructures have been fabricated by depositing p-type Mg 0.35 Zn 0.65 O films onto the nanowires [30], and the core-shell nanowire heterostructures have been bonded together with the p-type diamond via a direct contact method by a clip. A schematic illustration of the structure is shown in Fig.…”

Electrically pumped lasing has been one of the most challenging issues for random lasers. Since holes are rare in most semiconductors, hole injection is necessary for electrically pumped lasers. Here in this article, by employing p-type diamond synthesized via a temperature gradient method under high-pressure and high-temperature conditions as a hole source, electrically pumped random lasing has been observed from p-Mg 0.35 Zn 0.65 O∕n-ZnO core-shell nanowire structures. The mechanism for the lasing can be attributed to the recombination of the electrons in the nanowires with the holes injected from the p-type diamond. Fig. 6. Room temperature EL spectra of the p-Mg 0.35 Zn 0.65 O∕ n-ZnO core-shell nanowire heterostructures with p-type diamond as the hole source layer under different injection currents. The inset shows the dependence of the integrated emission intensity of the device on the injection current.

[19][20][21][22] According to the difference in cavity structures of the electrically pumped nanolasers, the nanolasers can be classified into Fabry-Perot cavity based (FP-based) electrically pumped nanolasers, [23][24][25][26] whispering gallery mode based (WGM-based) electrically pumped nanolasers, [27][28][29][30] random Cavity based (RC-based) electrically pumped nanolasers, [31][32][33][34][35][36][37][38] photonic crystal cavity based (PCC-based) electrically pumped nanolasers, [39][40][41][42][43][44] and metallic cavity based (MC-based) electrically pumped nanolasers. [45][46][47][48] All these cavity structures can provide sufficient gain feedback for realizing the electrically pumped nanolasers emission.…”

Electrically pumped nanolasers have achieved many exciting achievements and display a wide range of potential application prospects in the fields of optoelectronic chips, information storage, and biosensing. However, there is lacking an in-depth and extensive review of the recent development of electrically pumped nanolasers. Herein, a detailed and comprehensive overview of the electrically pumped nanolasers is first given according to the device configurations, including electrically pumped single nanolaser, nanoarray lasers, nanobeam lasers, and plasmonic nanolasers with different cavity structures. Furthermore, some problems and challenges restricting the development of electrically pumped nanolasers are summarized, and the corresponding solutions and development directions are proposed. This review will provide valuable suggestions for optimizing the device structure of electrically pumped nanolasers with new high-gain semiconductor materials and particularly further promote their rapid application development.
