A 1.3-μm directly modulated InGaAlAs-MQW DFB laser, incorporating an asymmetric corrugation-pitch-modulated (ACPM) grating, operating at 28 Gb/s at 55°C experimentally demonstrated high mask margin of 22% for the first time.
A modulator with an enhanced efficiency by cascaded microring resonators (MRRs), and a single-mode laser with a wavelength determined by a MRR wavelength filter were integrated on a Si chip to demonstrate for the first time wavelength-tuning-free 10-Gb/s modulation over a wide range of temperature.
A moving-magnet-type 2-axis MEMS scanner with a rotation angle detector has been developed. The fabricated MEMS scanner demonstrated a raster scan and 2-axis rotation angles detection with one Hall sensor.
A tunable LGLC laser monolithically integrated with dual-core SSC for tunable XFP modules has been developed. FWHMs of horizontal and vertical FFPs were narrowed to 20° and 25° under 0.5dB low excess loss in C-band.
We propose a new parameter obtained by three-fiber-based diffuse reflectance spectroscopy for nondestructive measurement, demonstrating a good linear correlativity of the parameter with the fruit sugar content by employing LEDs as light sources.
The dependence of the crystal orientation of YBa2Cu3O7-x deposited using an ArF pulsed laser on the post-deposition oxygen partial pressure during cooling was studied. The crystal orientation of films deposited in low oxygen partial pressure was found to change depending on the oxygen partial pressure during cooling after deposition, accompanied by solid phase regrowth. In order to investigate this...
