We measure characteristics of a transmitted WDM signal in an 80 km-long SMF under bi-directionally pumped DRA with incoherent-forward and coherent-backward pumps. The signal shows OSNR of 50.0 dB and RIN less than -140 dB/Hz.

Conference on Lasers and Electro-Optics.
A flexible metamaterial device consisting of metal split rings embedded in a transparent polymer film is demonstrated. The device is useful to construct three-dimensional metamaterial systems to develop novel terahertz- and photonic applications.

We analyzed two types of Mach-Zehnder plasmonic modulators on a silicon-on-insulator platform with a different furan-thiophene chromophore electro-optic polymer to compare to other reports. The metal-taper coupling structure and the metal-insulator-m

The in-plane and interlayer waveguide-type couplers between crystalline Si and amorphous-Si:H wire waveguides, for 2D/3D hybrid-material integration are presented in this paper. The in-plane–type coupler achieves stable coupling between two wavegui
