Transmission Characteristics of Tuneable Optical Filters Using Optical Ring Resonator with PCF Resonance Loop
Optical Ring Resonator Photonic Crystal Fiber Tuneable Optical Filter Optical Fiber
2013/1/30
A theoretical analysis of a tuneable optical filter is presented by proposing an optical ring resonator (ORR) using photonic crystal fiber (PCF) as the resonance loop. The influences of the characteri...
Quantitative phase retrieval with a sub-100-nm resolution is achieved from micrographs of a zone plate based transmission x-ray microscope. A plastic zone plate containing objects of sizes from microm...
Experimental Demonstration of 16-QAM Transmission with a Single Dual-Drive Mach-Zehnder Modulator
Dual-Drive Mach-Zehnder Modulator 16-QAM Transmission
2015/5/15
10-Gbit/s 16-QAM transmission over 160 km with a single dual-drive Mach-Zehnder modulator was experimentally demonstrated. We achieved BER<10 -9 in a BtB condition and <10 -7 after the transmission. E...
