We demonstrate 51.5625Gbps PAM4 transmission over ≥ 150 m next generation wide band MMF using SWDM TOSAs from 850 nm to 940 nm indicating an aggregated 206.25 Gb/s speed achievable on a single WBMMF.
We show that with simple spectral filtering, the Schmidt number for the transmitted photon-pairs (with 90% transmittance) which are produced via type-II parametric down-conversion in a KTP waveguide equals to unity to within 0.2%.
We present fabrication of 1.3-µm InAs QD-VCSELs and arrays. The output power of single VCSEL exceeds 1.2 mW. Modulation bandwidth of 2.65 GHz and 2.5 GHz are achieved for single-mode and multi-mode VCSELs. Maximum output power of 28 mW is demonstrated for VCSEL arrays with threshold current of 50 mA.
In this paper, we have proposed a framework of systems-on-chips clustering in application to complicated sensor networks. The framework can be applied to address the communication issues in distributed and large-scaled sensor nodes in wireless sensor network application. There are two communication categories under consideration, i.e. intra-nodes and inter-nodes. Due to the potentially higher frequency...
Motion estimation (ME) is one of the bottlenecks in terms of the computational cost in a video encoder system. In this paper, we present a cost-effective method to calculate the "Vector Edge" of the current frame. We store all the vectors' information within a frame and put them in the Laplacian of Gaussian edge detection operator. It is similar to the image edge detection but we need to...
Bandwidth is always one of the bottlenecks in system-on-a-chip (SoC) systems. In this paper, we propose an efficient architectural design in analyzing the bandwidth of each component in an H.264 design. We decompose the entire H.264 system bandwidths into several modules with predictable coefficients. The derived equations may help designers understand the real cost of each hardware component, thus...
