Recent research results on a green LED and solar cell based on ZnTe are reported. The wall plug efficiency of ZnTe LED has been improved to 0.15% by adopting a thin film structure, which is comparable to that of GaP-based green LED. The solar cell based on ZnTe with an efficiency of 1.42% has also been developed. The fundamental results on ZnTe solar cell provide a basis for future development of intermediate band solar cells based on ZnTe-related materials.

We demonstrate that in a tight focusing geometry circularly polarized femtosecond laser vortex pulses ablate material differently depending on the handedness of light. This allows one to control laser micromachining on a sub-wavelength scale.

We show how k-space spectroscopy distinguishes between the surface-plasmon (SP) and photon nonlinear interactions for SHG when metal films are excited in the Kretschmann-geometry, and confirm that two SP annihilate to create a second-harmonic photon.

We demonstrate for the first time stable self-trapping and self-induced transparency of light propagating in colloidal nano-suspensions with negative polarizabilities. Comparing to “polystyrene-water”-colloidal systems with positive polarizabilities, a fivefold increase in transmission ratio is achieved.
