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.

A unique combination of microlens and pillar on the facet of single mode fiber is proposed and examined to achieve high coupling efficiency to small spot size of silicon photonics. Pillar and microlens are fabricated by Self-Written Waveguide (SWW) method and dipping method, respectively using UV-curable resin.

We experimentally demonstrated the plasmonic color modulation by dynamically controlling the interparticle distance of the crystalline Ag nanocube monolayer on the stretchable substrate. The transmitted light color modulated from magenta, orange to yellow by stretching of the substrate under random polarization incidence.

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.
