Optical wireless communication (OWC) has attracted significant interest recently in industry and academia. In this talk, we will focus on LiFi networking which is high speed wireless networking with light. We will discuss the latest device technologies and system elements such as optical transceivers composed of massive transmitter and detector arrays. This talk will also review photovoltaic cells as high-speed data detectors towards energy self-sufficient optical wireless access.

Localized surface plasmon resonance is generally excited by light. However, more localized excitation is expected to be achieved by electron beam irradiation. In this study, we irradiated metal nanoparticles with an electron beam using a scanning electron microscope and measured their optical responses.

We present the modeling of an ultrahigh speed transverse-coupled-cavity (TCC) VCSEL, which shows the improvement of the optical feedback tolerance. The critical feedback level is increased with increasing the coupling strength, which enables an isolator-free operation of single-mode VCSELs for use in single-mode fiber transmissions.

We proposed a new beam steering method of a terahertz wave generated by the photomixing using difference in the chromatic dispersion between the single mode fiber (SMF) and the dispersion compensation fiber (DCF). We experimentally confirmed that the peak position of the terahertz waves shifts by 65 degrees.

We have developed live cell autofluorescence imaging system with DUV-SPR. We measured the intensity reflectance of the laser beam in the Kretschmann configuration for P and S-polarized light, and confirmed that the SPR was excited by P-polarized light. The autofluorescence of living HeLa cells was imaged using the excited DUV-SPR.

Single crystal diamond has been widely recognized as an outstanding material for optics, yet precision shaping and structuring has traditionally proven challenging due to hardness and chemical inertness. We here summarize our recent advances in micro- and nanostructuring techniques demonstrating high quality micro-optical components in single crystal diamond.

We report on fabrication of metallic nanostructures in dielectric materials by controlling polarization of the irradiating femtosecond laser. Formation of Laser-Induced Periodic Surface Structures via multiphoton absorption-induced photoreduction of silver ions is exploited to realize metallic nanostructures by changing polarization of the exciting laser. Possible formation mechanisms are outlined.
