Near-field technology
The size of the devices have been reduced to nano-meter scale to meet the requirement using “nanotechnology. Optical near-field (ONF) has made it possible to reduce the size of photonic devices to the sub-wavelength scale or smaller. For further development of the photonics we are interested in the use of the unique properties of ONF, which are originated from the non-uniformity of the electric and/or magnetic field in nano-scale. Using the ONF, we realized unconventional photo-reaction, resulting the nano-scale device and sub-nanometer scale fabrication process.

Direct excitation of the carrier in the indirect bandgap

ONF could excite the interband transitions between different wave -vectors according to the uncertainty principle. .
