The design of application-specific integrated circuits (ASIC) is at the core modern ultra-high-speed transponders employing advanced digital signal processing (DSP) algorithms. This manuscript discusses motivations for jointly utilizing transmission techniques such as probabilistic shaping and sub-carrier multiplexing in coherent optical transmissions systems. First, we describe key-building blocks high-speed DSP-based working up to 800G per wave. Second, show benefits these methods terms...
The various topologies, traffic patterns and cost targets of optical networks have prevented the deployment end-to-end solutions across multi-domains, optimization network as a whole. consequent limitations in flexibility, scalability, adaptability will become increasingly important with new applications, such 5G/6G. Coherent transceivers based on digital subcarrier multiplexing (DSCM) are proposed to address these current constraints. In particular, DSCM allows (i) design high-capacity...
A photoionization detector (PID) is well known for its high sensitivity, large dynamic range, and non-destructive vapor detection capability. However, due to tardy response, which results from the relatively ionization chamber dead volume, application of PID in gas chromatography (GC) has been limited. Here, we developed a rapid, flow-through, highly sensitive microfluidic that was microfabricated directly on conductive silicon wafer. The significantly reduced volume only 1.3 μL, nearly 10...
Abstract This report concerns a benchtop prototype instrument containing gas chromatographic microanalytical system (μGC) designed for the selective determination of multiple airborne volatile organic compounds (VOCs) at concentrations in vicinity recommended occupational exposure limits.
