We have for the first time fabricated a hexagonal core fiber by soft glass in the core size of one micron. The supercontinuum generation from this fiber by the pump of picosecond pulse is demonstrated.
In this paper we present the design concept and experimental evaluation results of a newly developed DWDM Radio on Free Space Optics (RoFSO) system capable of transmitting simultaneously multiple RF service signals. The system performance is evaluated under effects of atmospheric turbulence over 1-km free-space transmission. Effectiveness of a proposed tracking scheme used to mitigate beam angle-of-arrival...
The authors present the design, dispersion calculations and tailoring, and parametric gain calculations for the composite tellurite fluorophosphate glass fiber. The authors show that it is possible to design the zero flattened dispersion fiber or the fiber providing two ZDWLs in the communication band, which in turn can generate broadband parametric amplification. The authors study the effect of dimensional...
Radio on Free Space Optical Link (RoFSO) has been developed to realize a cost effective and universal platform for heterogeneous wireless services as same as RoF. This paper proposes a new link loss model for RoFSOL based on a long-term experiment of RoFSO transmission and a total system design method for four types of wireless services.
With the increase of communication demand and the emergence of new services, various wireless technologies have been deployed recently. To achieve the goal of ubiquitous communication, however, a universal platform is necessary to connect all the network facilities and make them communicate together. The transmission of radio on fiber (RoF) has been realized as an attractive means to reach this target...
Radio on free space optics (RoFSO) is being developed to realize a cost effective and universal platform for heterogeneous wireless services as same as RoF. The developed RoFSO transceiver can directly transmit some RoF signals from an optical fiber and can receive an RoFSO signal from air into a fiber core. It can achieve an free space that is transparent for various types of wireless services in...
In a ubiquitous network society, a universal platform is necessary to satisfy customerspsila increased demand on communication at any-time, anywhere and any-situation. Radio on fiber (RoF) technologies can realize a cost effective universal platform for ubiquitous wireless services. RoF networks can also be extended to radio on free space optics (RoFSO) providing communication links for heterogeneous...
Transmission of modulated RF signal using FSO communications links is receiving a lot of research interest recently. We are developing a new advanced DWDM RoFSO link system capable of transmitting multiple RF signals. In this paper, we present results from analytical modeling reflecting on the design parameters of the RoFSO system to evaluate and predict its performance. The parameters of interests...
