2. Modulation Optimization for Noncoherent Optical Systems
Abstract : There has been a significant improvement in high-speed electronics and optical components over the past few years, and this is one of the key enabling factors for high data rate transmission. Moreover, multi- level modulation formats, which encode information onto the carrier’s amplitude and phase, are necessary to increase the spectral efficiency of communication systems. READ MORE

3. Multilevel modulation in short-range optical links
Abstract : Power and cost efficient short-range optical links are one of the technologies enabling large scale high-performance computers and data centers. Such links typically use directly modulated vertical cavity surface emitting lasers, multi-mode fiber, direct detection and on-off keying (OOK) modulation. READ MORE

4. Advanced modulation formats for short-range optical communications
Abstract : The demand for faster short range optical links is increasing and simple modulation techniques, such as on-o keying do not scale well to higher data rates, because of the limited bandwidth-distance product of the multimode ber. The industry has responded to this problem by aggregating multiple parallel links operating at lower bit-rate. READ MORE
