Complex and informative luminescent spectra have been obtained by using visible sources for excitation of InGaAsP/InP double heterostructure diode wafers. The thin contact layer transforms the high energy exciting light to lower energy photons which can excite the active layer, although the InP confining layers are not transparent for primary exciting photon.

We present the first detailed account of kaleidoscope laser modes where the equivalent Fresnel number Neq and magnification M may assume arbitrary values. Properties of these linear fractal eigenmodes are explored through extensive numerical computations. Considerations are extended to demonstration and analyses of new contexts for spontaneous nonlinear optical fractals.

Nonlinear modes and switching characteristics of plasmonic directional couplers are studied. The structures are created by two neighbouring metal-dielectric-metal waveguides with the slots filled in a nonlinear dielectric material. The different nonlinear modes are calculated, and the FDTD numerical simulations are carried out to study the power transfer in such plasmonic couplers and evaluate the effect of optical losses on the coupler switching characteristics.

A vertical-cavity surface-emitting laser (VCSEL) based on (110) InGaAs/GaAs multiple quantum wells (MQWs) was fabricated and characterized. Circularly polarized lasing by optical pumping was demonstrated. A high degree of circular polarization, 0.94, was observed at 77 K, reflecting the long electron spin relaxation time in the (110) MQWs.

Device structures in high refractive index materials, notably semiconductors such as silicon, will form the basis for high-density integrated photonics. Nanometre-scale structuring - in conjunction with photonic crystal, photonic wire and plasmonic/metamaterial principles - will be required in order to realise the full potential for a variety of applications.

Solutions containing dsDNA fragments were irradiated with UV laser pulses. The produced damage was investigated using polyacrylamid gel electrophoresis. The intensity of cleavage in particular phosphodiester bond after hot alkali treatment of irradiated samples was shown to depend on base pair sequence. The damage of DNA fragments has occurred predominantly in the sites containing guanine clusters.
