Journal ArticleDOI
Optical carrier supply module using flattened optical multicarrier generation based on sinusoidal amplitude and phase hybrid modulation
Masamichi Fujiwara,Mitsuhiro Teshima,Jun-ichi Kani,Hiro Suzuki,Noboru Takachio,Katsumi Iwatsuki +5 more
TL;DR: In this paper, an optical carrier supply module (OCSM) was proposed for superdense wavelength division multiplexing (SD-WDM) networks that utilize a large number of wavelengths with narrow channel spacing.

Multiwavelength simultaneous monitoring circuit employing arrayed-waveguide grating
TL;DR: In this paper, a multi-wavelength simultaneous monitoring circuit capable of precise discrimination of wavelengths of a WDM (Wavelength Division Multiplexed) signal including multiplexed wavelength waves, and suitable for optical integrated circuits having large resistance to vibration is presented.
Journal ArticleDOI
A WDM-based optical access network for wide-area gigabit access services
Jun-ichi Kani,Mitsuhiro Teshima,Koji Akimoto,Noboru Takachio,Hiro Suzuki,Katsumi Iwatsuki,M. Ishii +6 more
TL;DR: A WDM-based access network that directly connects end users over a wide area to the center node and provides guaranteed full-duplex Gigabit Ethernet access services to each of over 100 users is proposed and demonstrated.
Journal ArticleDOI
Performance of multiwavelength simultaneous monitoring circuit employing arrayed-waveguide grating
TL;DR: In this article, the authors proposed a multi-wavelength simultaneous monitoring (MSM) circuit that uses the wavelength crossover properties of an arrayed-waveguide grating (AWG).
Patent
Optical communication system, optical communication unit, and optical transceiving package
TL;DR: In this article, the authors proposed using spectrum-sliced modulated broadband light for transmitting upstream signals instead of using laser light in an optical communication system, which is applicable to wavelength-division multiplexing systems.
