This paper presents the results of a study of silicon multilayered structures in the near-infrared region (wavelength range 0.8–1.7 µm). The quasi-periodic layered systems are created when two different layers with alternative high (H) and low (L) refractive index are arranged according to the following relations: equation, where x= mλ/4, (m-1,2 …)- is the effective optical thickness of the arbitrary...
We present the theoretical analysis of resonance quantum cascade photodetector based on GaN/AlGaN compound. Calculation of reflection, transmission spectra and optical quantum efficiency was made by semianalytical methodic.
In this work, the simulation of the 980 nm InGaAs intracavity-contacted oxide-confined vertical-cavity surface-emitting lasers (ICOC VCSELs) with separated triplets of quantum wells (STQW) is presented. We analyze the thermal, electrical and optical properties of such devices. Results of simulations show the larger optical power efficiency and higher modulation bandwidth for devices with included...
The model for description of one-dimensional anisotropic photonic crystals based on anisotropic porous silicon is proposed. The finite difference technique is applied for the scattering matrix parameter computation. Reflectance spectra for two orthogonal polarizations of the incident plane wave are calculated. The dependence of the shift of the spectral position of the photonic band gap edges on the...
