Band structure calculations are performed by k·p theory on lattice-matched (LM) and strain-compensated (SC) interdiffused GaInAs(P)/GaInAsP quantum wells (QWs) designed for 1.55 μm wavelength response. The evolution of the in-plane band structures

We have investigated the temperature dependence of the fundamental absorption edge of a series of Hg1−xCdxTe alloys (with composition x ranging from 0.5 to 1). Analyzing our data in the light of the three‐dimensional theory of direct‐allowed ex

The uniaxial stress‐induced coupling of the optical ordinary and extraordinary modes in CdS is quantitatively investigated by analyzing, at room temperature, the transmitted light spectrum of a sample placed between two polarizers crossed along the

We provide a quantitative picture of the characteristics of a CdS coupled‐mode band‐pass optical filter. The operating principle of these coupled mode filters (CMF) is the energy exchange between the ordinary and extraordinary modes when the samp

Localized defects are investigated in p-CdTe:Cu doped by copper incorporation during Bridgman growth. The results of Hall measurements, admittance spectroscopy and photoluminescence (PL) are similar to those obtained from samples Cu-doped by ion-impl

The acoustic domain formation in semiconducting CdS crystals with with their c axis parallel to the applied electric field is discussed. For the first time the Brillouin scattering technique is used not only for on-axis phonons but for the whole spat

The spectral range of operation of optical coupled‐mode filters (CMF) is investigated. The CMF principle is based upon the stress‐induced energy transfer between orthogonal polarized optical modes, which occurs in birefringent materials at the is

Tunable narrow‐band optical filters over a wide spectral range are constructed. These use the efficient coupling of orthogonally polarized optical waves near the isotropic wavelength in graded‐composition mixed crystals of CdS1−x Sex and Zn1−
