Recent Developments on Optical Single Sideband Transmission Systems

Abstract

Optical single sideband (OSSB) modulation has been recently proposed to increase the spectral efficiency of next generation transmission systems. Contrary to other spectrally efficient optical modulations, simple electrical compensation techniques can be used together with OSSB to mitigate the impairment of fibre dispersion. In this paper, we present recent results on the use of electrical dispersion compensation (EDC) with OSSB modulation and assess ways to improve the EDC efficiency by using formats other than the conventional binary format. 1.

Optical single sideband modulation using fiber nonlinearity and injection locked technology in radio‐on‐fiber systems

“…For example, an axisymmetric geometry is often used for high-Q cavities, which strongly confine light by total internal reflection. These whispering gallery mode (WGM) resonators are shown to exhibit a very high Q in various configurations [1][2][3][4]. Photonic crystal (PhC) structures are widely used to realize a very small mode volume, which greatly increases the spectral spacing of the eigenmodes and enhances the Purcell factor [5][6][7].…”

“…The beating components between the carrier and two sidebands induce interference at the receiver. Over a long haul fiber transmission, radio frequency (RF) signal will cause severe power degradation due to chromatic dispersion . In order to overcome RF power degradation, optical single sideband (OSSB) modulation technique must be implemented.…”
