Dynamic Characterization of Optical-Microwave Transducers
Optical-microwave transducers based on FET devices are investigated to determine their dynamic characteristics. It is observed that the result of the well known frequency response method differs from that of a combined ...
Microwave Characterization of High-Speed pin Photodiodes
Optical responsivity and electrical reflection of an ultra high-speed pin photodiode (PD) are measured in 20 GHz frequency range. The effect of PD bias voltage variation was investigated at different incident optical power ...
Interference Sensitivity of Digital Receivers in Fiber-Radio Distribution Networks
Fiber-radio distribution networks have been investigated by several authors recently. In such networks wideband access of several subscribers is provided with the advantage of easy installation and reduced maintenance costs ...
Numerical Model of Chromatic Dispersion Effects in Analogue IM/DD Optical Links
Transmission of microwave (uW) and millimeter-wave (mmW) carriers optically at 1.55 um wavelength has become an important task recently. A main field of potential applications is the optical transmission and wireless ...
Optical Link Simulation
Techniques for the modeling of analog and digital communication systems fall into two classes. Those based on component aspect, those based on system aspect. An approach of these techniques applied to optical fiber link ...
Radio-Node Upconversion in Millimeter-Wave Fiber-Radio Distribution Systems
Optical generation and distribution of millimeter waves have become an intensive research topic recently [1,2]. A main field of possible applications is the millimeter-wave (MMW) wireless distribution of broadband data in ...
Remote Upconversion in Microwave Fiber-Optic Links Employing an Unbalanced Mach-Zehnder Interferometer
We present a new technique for remote upconversion by inserting a passive all-optical device in the microwave (MW) fiber-optic link. Using a semiconductor laser directly modulated by two MW signals and an unbalanced ...
Optical Upconversion of 100 Mb/s BPSK Microwave Subcarrier Signals Using an Unbalanced Mach-Zehnder Interferometer
A new technique for remote upconversion of a 100 Mb/s BPSK microwave subcarrier signal is proposed and demonstrated. It is based on the insertion of an unbalanced Mach-Zehnder interferometer in a microwave fiber-optic link.
