Hybrid Fiber Amplifier [PDF]

open access: yes, 2012
The advent of telecommunications in 1870s completely revolutionized the world of communications. Metallic cables consisting of twisted wire cables, co-axial cables were the media of choice for many years. These could be used efficiently up to frequencies of 10MHz but the system performance degraded beyond this range. However, with the increasing demand

Multiple RF carrier distribution in a hybrid radio/fiber system employing a self-pulsating laser diode transmitter [PDF]

open access: yes, 2002
A self-pulsating laser diode is used to generate a multicarrier microwave optical signal for use in a hybrid radio/fiber system. The self-pulsation frequency of the laser is controlled by external light injection, and can be varied between 14-24 GHz. The

A hybrid mode locked laser as millimetre wave modulated data source for radio-over-fiber systems [PDF]

open access: yes, 2009
The paper presents a characterisation of a hybrid mode locked laser under external injection locking. It shows how such a system can be used to transmit baseband data without the requirement of an external ...

Remote downconversion scheme for uplink configuration in radio/fiber systems [PDF]

open access: yes, 2005
The authors present a novel technology for uplink transmission in radio over fiber (RoF) distribution systems. The technique employs remote downconversion of the uplink data to intermediate frequency (IF) in the base station (BS).

Improved performance of a hybrid radio/fiber system using a directly modulated laser transmitter with external injection [PDF]

open access: yes, 2002
A directly modulated laser diode with external light injection is used to generate microwave optical signals for a hybrid radio/fiber system. The external light injection greatly enhances the frequency response of the laser, and thus, significantly ...
