Monitoring Junction Temperature of RF MOSFET under Its Working Condition Using Fiber Bragg Grating
Micromachines, 2022 When a high-power radio frequency (RF) metal oxide semiconductor field effect transistor (MOSFET) works in low-efficiency situations, considerable power is dissipated into heat, resulting in an excessive junction temperature and a likely failure. In this

Flexible Multi-Thread Dynamic Bandwidth Allocation Algorithm in VPONs Based on LR WDM/TDM PON
IEEE Access, 2020 With the smooth upgrade of the access network, multiple tuning-time devices will coexist in the long-reach access network, and the subsequent problems of high round-trip time (RTT) and optical network unit (ONU) tuning delay need to be solved urgently ...

3 W average-power high-order mode pulse in dissipative soliton resonance mode-locked fiber laser
Nanophotonics, 2021 Recently high-order modes (HOMs) lasers have been extensively investigated due to their potential applications in mode-division multiplexing. In this paper, we present two schemes of generating HOMs from the mode-locked fiber lasers (MLFLs) in the ...
