A physical model is established to describe the kinetic process and the laser amplification mechanism of a diode side pumped alkali vapor laser MOPA system. The pump energy distribution inside the vapor cell is displayed. Taking into consideration the amplification saturation effect, the influences of the parameters, such as the temperature, cell length, and pump power on the output performance, a...

Near-ultraviolet nitride-based light-emitting diodes (LEDs) were prepared on GaN nanorod arrays (NRAs). Transmission electron microscopy results show that the NRAs partially block threading dislocation propagation from the GaN template. Compared with conventional LEDS, the output power of the prepared LED using GaN NRAs with an injection current of 20 mA was enhanced by a factor of 1.67. View full abstract»

The small signal gain and phase and polarization distortions of laser radiation have been investigated theoretically and experimentally in end-pumped Yb:YAG thin-disk and Yb:YAG/YAG composite active element under nonlasing conditions. Comparison of experimental data with calculation results reveals an additional heat release whose negative influence is three times stronger than that of amplified s... View full abstract»

Recent experimental work has demonstrated that the light extraction enhancement due to scattering by a metallic nano-grating in an InGaN/GaN quantum well (QW) structure can be improved significantly by burying the grating in a dielectric, such as polyvinyl alcohol (PVA). In this paper, we employ the fluctuational electrodynamics method to investigate the origin of this improvement and to provide g... View full abstract»

We investigate numerically the synchronization of two multimode semiconductor ring lasers (SRLs) and demonstrate its potential in chaos-based communication. The extent of the SRL's chaos regime under external optical feedback is evaluated in terms of bifurcation diagram and the optimal feedback strength range for reliable chaotic communication is discussed as well. Under proper conditions, the rec... View full abstract»

| | PDF (2718 KB) | HTML

The gain saturation factor describes the proportionality between the real and imaginary parts of the optical susceptibility associated with the circulating optical field in the laser cavity. This factor depends on where the laser operates relative to the gain peak. The effects of the gain saturation factor on the characteristics of the nonlinear phenomena induced by optical injection are studied t... View full abstract»

An AlGaN deep ultraviolet laser diode design exploiting AlN substrates is presented, featuring an inverse-tapered p-waveguide layer. The 2-D optoelectronic simulation predicts lasing at 290 nm. Spatial balancing of the lasing mode to minimize optical loss in the p-Ohmic metallization is achieved through the use of a narrow bandgap yet transparent n-waveguide layer. Several electron blocking layer ... View full abstract»

We perform a rigorous analysis of the temperature dependence of the spontaneous emission factor, β, in subwavelength semiconductor lasers. The analysis combines a recent formulation of the Purcell effect in semiconductor nanolasers with finite-element modeling and established theoretical models for temperature-dependent emission spectra. While the method is general, we apply it to a subwave... View full abstract»

A method to synthesize a fiber Bragg grating (FBG) providing a desired, arbitrary stationary power/field distribution along the grating length is proposed and numerically demonstrated. In the proposed method, starting from the desired stationary power/field distribution or its differential at the Bragg wavelength, the forward and the backward propagation modes are derived for a uniform-period FBG ...
