Abstract
The present work deals with the performance investigation of bandwidth-efficient optical fiber communication systems. In this paper, novel 2-D orthogonal hybrid optical modulation techniques are proposed. In the proposed fiber optic communication system for dense wavelength-division multiplexing (DWDM), optical modulation techniques minimum shift keying (MSK) and pulse amplitude modulation (PAM) are simultaneously modulated at 100 GHz channel spacing with a minimum utilization bandwidth of 4.3 THz. The results show a significant advantage in using the proposed hybrid optical modulation techniques in offering high bandwidth optical signal-to-noise ratio with an acceptable quality factor.
