چکیده

We experimentally determine the lasing mode(s) in optically pumped semiconductor nanowire lasers. The spatially resolved and angle-resolved far-field emission profiles of single InP nanowire lasers lying horizontally on a SiO2 substrate are characterized in a microphotoluminescence (μ-PL) setup. The experimentally obtained polarization dependent far-field profiles match very well with numerical simulations and enable unambiguous identification of the lasing mode(s). This technique can be applied to characterize lasing modes in other type of nanolasers that are integrated on a substrate in either vertical or horizontal configurations.

Size reduction of a semiconductor nanowire laser using metal coating

We explore the possibility of coating semiconductor nanowires with metal (Ag) to reduce the size of nanowire lasers operating at photon energies around 0.8–2 eV. Our results show that the material gain of a typical III-V semiconductor in nanowire may be sufficient to compensate Joule losses of such metal as Ag. The most promising mode to achieve lasing seem to be TM01 near its cutoff. To calcul...

Tailoring the lasing modes in semiconductor nanowire cavities using intrinsic self-absorption.

Understanding the optical gain and mode-selection mechanisms in semiconductor nanowire (NW) lasers is key to the development of high-performance nanoscale oscillators, amplified semiconductor/plasmon lasers and single photon emitters, and so forth. Modification of semiconductor band structure/bandgap through electric field modulation, elemental doping, or alloying semiconductors has so far gain...

Ultra-high quality factor optical resonators based on semiconductor nanowires.

We propose a platform to achieve ultra-high Quality factor (Q) optical resonators based on semiconductor nanowires. By defining onedimensional photonic crystal at nanowire ends and engineering the microcavity pattern, cavities with Q of 3 x 10(5) and mode volume smaller than 0.2(lambda/n)(3) have been designed. This represents an increase of almost three orders of magnitude over the Quality fac...

Semiconductor nanowire ring resonator laser.

Nanowires of the wide band-gap semiconductor gallium nitride (GaN) have been shown to act as room-temperature uv lasers. Recent advances in nanomanipulation have made it possible to modify the shape of these structures from a linear to a pseudoring conformation. Changes to the optical boundary conditions of the lasing cavity affect the structure's photoluminescence, photon confinement, and lasi...
