Research Abstract |
I studied on realizing and fabricating a prototype device of an ultrafast all-optical switching of two-photon absorption type in wide wavelength range. Polarization dependences of two-photon absorption coefficient in InP were measured in wavelength range of 1640 nm to 1800 nm. The third-order susceptibility tensor of InP was calculated from the above results. Ridge waveguides of InP were fabricated by dry-etching, which had smooth etched surfaces and almost vertically etched side walls.
