    Language:English   Publisher:INSTITUTE OF PURE AND APPLIED PHYSICS  

    The photoluminescence (PL) characteristics of InAs quantum dots on a GaNAs buffer layer grown by metalorganic chemical vapor deposition were investigated. A maximum 60 nm redshift was observed for a nitrogen composition of less than 3% in the buffer layer with an increase in emission efficiency in comparison with a conventional GaAs buffer layer. A large intensity increase with a blueshift of PL was observed for a buffer layer of 3% nitrogen composition. These were due to a change in the dot morphology on the GaNAs buffer layer. The InAs supply and growth temperature dependences of PL properties were also examined in detail.

    The force of bow holding and the contact force between bow hair and string in violin playing were measured by a pressure measuring film for the first time. It was scientifically identified that relaxed bowing was important for achieving a good violin tone. The proposed measurement manner may be helpful for objective evaluation of the bowing skill of amateur violinists.

    We propose a hollow optical waveguide with metal coating or dielectric multilayer coating to achieve sufficient reflectivity at guiding walls. Low-loss and polarization-insensitive propagation characteristics are predicted. The propagation constant is independent of the temperature, resulting in temperature-insensitive photonic waveguide devices, such as optical filters and grating optical demultiplexers. We demonstrate a hollow optical waveguide with metal-coated walls on a GaAs substrate, which was fabricated using dry etching. The propagation loss including the coupling loss with an input fiber was 2.6 dB/cm and 7.3 dB/cm for transverse electric (TE) mode and transverse magnetic (TM) mode, respectively.

    A tunable laser is a key device for providing flexibility and functionality in future Wavelength Division Multiplexing networks. We propose a novel optically pumped tunable surface emitting laser. The lasing wavelength of the device can be varied by changing the photo-pumped position of a vertical cavity with a spatial gradient in the cavity length. A possibility of mode-hop-free wide wavelength tuning is presented over current existing tunable lasers. We fabricated a GaInAsP/InP short cavity and measured the resonant spontaneous emission of an optically pumped cavity with spatial gradient. The change of the resonance peak is as large as 40 nm. The obtained result shows the possibility of large continuous wavelength tuning.
