چکیده
In article number 2006819, Chien-Chih Lai and co-workers report the first demonstration of a diode-pumped ultralow-threshold continuous-wave room-temperature perovskite laser, by coating MAPbI3 nanocrystallites onto high-quality yttrium aluminum garnet (YAG) crystal fiber. The atomically smooth fiber not only serves as perfect microcavity for ultralow-loss optical resonance but also facilitates heat dissipation toward robust laser devices, outperforming previously reported structures. This readies ground electrically driven lasers all-optical photonic integration.

Ultrafast photonic crystal lasers
We describe recent progress in photonic crystal nanocavity lasers with an emphasis on our recent results on ultrafast pulse generation. These lasers produce pulses on the picosecond scale, corresponding to only hundreds of optical cycles. We describe laser dynamics in optically pumped single cavities and in coupled cavity arrays, at low and room temperature. Such ultrafast, efficient, and compa...
متن کاملNanobeam photonic bandedge lasers.
We demonstrate one-dimensional nanobeam photonic bandedge lasers with InGaAsP quantum wells at room temperature from the lowest dielectric band of photonic crystal nanobeam waveguides. The incident optical power at threshold is 0.6 mW (effectively ~18 μW). To confirm the lasing from the dielectric bandedge, the polarization and the photoluminescent spectra are taken from nanobeams of varying la...

A novel type of nanolasers, which combines the advantages of photonic crystal lasers and microdisk lasers, has been demonstrated based on InAlGaAs/InGaAs quantum wells using pulsed optical pumping at room temperature. It incorporates the properties of small footprint, small mode volume, and submilliwatt threshold, and favors vertical emission. We believe that this type of laser acts as a promis...
متن کاملPhotonic quasi-crystal terahertz lasers
Quasi-crystal structures do not present a full spatial periodicity but are nevertheless constructed starting from deterministic generation rules. When made of different dielectric materials, they often possess fascinating optical properties, which lie between those of periodic photonic crystals and those of a random arrangement of scatterers. Indeed, they can support extended band-like states w...
متن کاملAntenna coupled photonic wire lasers.
Slope efficiency (SE) is an important performance metric for lasers. In conventional semiconductor lasers, SE can be optimized by careful designs of the facet (or the modulation for DFB lasers) dimension and surface. However, photonic wire lasers intrinsically suffer low SE due to their deep sub-wavelength emitting facets. Inspired by microwave engineering techniques, we show a novel method to ...
