The results of studies of quantum-cascade laser with a surface emission through a grating formed in the layers of the top cladding of the waveguide by ion beam milling are presented. The active region of the QCL heterostructure was formed based on a heteropair of In0.53Ga0.47As / Al0.48In0.52As solid alloys with two-phonon resonance design. It is shown that lasing at room temperature close to 7.9 µm is demonstrated for a laser with a ring diameter of 191 µm. The mode spacing corresponds to whispering gallery modes.

AbstractThe manipulation of light emitted by two-dimensional semiconductors grounds forthcoming technologies in the field of on-chip communications. However, these technologies require from the so elusive out-of-plane photon sources to achieve an efficient coupling of radiated light into planar devices. Here we propose a versatile spectroscopic method that enables the identification of the out-of-plane component of dipoles. The method is based on the selective coupling of light emitted by in-plane and out-of-plane dipoles to the whispering gallery modes of spherical dielectric microresonators, in close contact to them. We have applied this method to demonstrate the existence of dipoles with an out-of-plane orientation in monolayer WSe2 at room temperature. Micro-photoluminescent measurements, numerical simulations based on finite element methods, and ab-initio calculations have identified trions as the source responsible for this out-of-plane emission, opening new routes for realizing on-chip integrated systems with applications in information processing and quantum communications.

Photodiodes developed in the GaSb-InAs system were first used for investigation the spectral characteristics of single and coupled disk lasers emitting on whispering gallery modes at 2.2–2.3 µm. The capacity of the photodiodes with a diameter of photosensitive area of 2.0 mm was C=520 pF at U=−2 V, which corresponds to a time constant of tau=53 ns. It is shown that the parameters of the developed photodiodes make it possible to detect the emission of quantum-sized disk lasers at room temperature and not to use cryogenic cooling.

We fabricated and characterized record small microdisk resonators in thin (210 nm) 3C-SiC film grown on Si (100) substrate. It was found to support high quality factor whispering gallery modes at visible wavelengths. We demonstrated room temperature coupling of these modes to the intrinsic photoluminescence of 3C-SiC at room temperatures and identified their polarization. Finally, we discussed applications for quasi-phasematched second harmonic generation from infrared visible wavelengths.
