This review presents a reflection-type holographic memory using three-dimensional(3D) speckle-shift multiplexing. First, the schematic of the proposed memory system was described. Then, experimental d...
A two-span SDM system includes the first ROADM supporting spatial superchannels and the first cladding-pumped multicore-EDFA directly spliced to multicore transmission fiber.For 6 ×40 ×128-Gb/s SDM-WD...
We report fabrication of the first low-loss, broadband 37-cell photonic bandgap fiber.Exploiting absence of surface modes and low cross-talk in the fiber we demonstrate mode division multiplexing over...
In this paper, we analyze the impact of analog-to digital convertor (ADC) bandwidth and clipping ratio on the performance of a 1 Gb/s x 15 user CDM-over-fiber-PON (COF PON) system based on 16-QAM modu...
We experimentally demonstrate reconfigurable switching of four 10-Gb/s tributary channels of 40-Gb/s data using a programmable planar lightwave circuit and nonlinear wavelength conversion. Our device ...
We experimentally demonstrate optical multiplexing of 40-Gbit/s channels at different wavelengths onto a single 640-Gbit/s channel and subsequent 640-to-10-Gbit/s demultiplexing using cascaded nonline...
A 30Gbit/s 3 × 3 optical Mode Group Division Multiplexing system with Mode-Selective Spatial Filtering (MSSF) using single-mode fiber is demonstrated over 20m graded-index multimode fiber. Crosstalk a...
We realized mode-division multiplexing(MDM) transmission by using orthogonal LP modes with negligible modal crosstalk, for the first time. A 2x10Gbps MDM transmission was achieved over a 10km two-mode...
We propose a novel graph model for multiplexing optimization in optical networks and evaluate the performance of several multiplexing policies. Simulation shows that our advocated multiplexing policy ...
A time lens system synchronizes a 10G Ethernet asynchronous data frame to a local master clock and converts the NRZ-frame to an RZ-frame and multiplexes it into a 330 Gbit/s aggregated Optical TDM sig...
Specific fibre modes are deliberately excited in a few-mode and multimode fibre using holography. The same system is also used to demonstrate holography’s ability to detect and route individual fibre ...
We developed an ultra-broadband all-optical frequency multiplexing technique on asingle optical carrier using cross-phase modulation in nonlinear fibers, and demonstrated sequentially multiplex of mul...
Digital Subcarrier Multiplexing (DSM) allows simple direct detection of spectrally effi-cient multicarrier signals. We show through simulations that, by using DSM, the quality of DWDM transmission wit...
A symmetric WDM-PON architecture using an innovative overlapped-SCM scheme that maximizes the spectrum usage of a bandwidth-limited RSOA is demonstrated. Error-free operation is achieved using realist...
Fiber capacity increase by coherent mode multiplexing requires inline optical amplification for cost and energy efficiency. Erbium doped and distributed Raman fiber amplifier concepts are evaluated co...
