Direct CATV modulation and phase remodulated radio-over-fiber transport system.

A novel transport system, with directly modulating community antenna television (CATV) signal downstream and phase-remodulating radio-over-fiber (ROF) signal upstream, is proposed and experimentally demonstrated. By modulating multi-carriers CATV signal in amplitude domain and ROF signal in phase domain, a single optical wavelength is able to serve these two applications simultaneous. To be the...

Reflection-mode optical injection locking.

A novel model including the interference effect of master laser reflection is established for reflection-mode optical injection locking. This model sheds insight on the physical origin of some rather distinct but unexplained modulation characteristics of optical injection-locked vertical-cavity surface-emitting lasers (VCSELs), including data pattern inversion in on-off keying modulation, a lar...

Coded Modulation Techniques for Direct-Detection Optical Fiber Communication Systems with Optical Amplifiers

In this paper, we investigate spectrally efficient coded multilevel modulation for direct-detection optical fiber communication systems with optical amplifiers. The dominant noise in the received photocurrent is the beat noise of amplified spontaneous emission with signal and itself. Although the decision variables are higher-order Chi-square distributed, we approximate them by first-order Chi-...

DIRECT ADAPTIVE FUZZY PI SLIDING MODE CONTROL OF SYSTEMS WITH UNKNOWN BUT BOUNDED DISTURBANCES

An asymptotically stable direct adaptive fuzzy PI sliding modecontroller is proposed for a class of nonlinear uncertain systems. In contrast toother existing approaches of handling disturbances, the proposed approachdoes not require this bound to be known, only requiring that it exists.Moreover, a PI control structure is used to attenuate chattering. The approachis applied to stabilize an open-...

COMPARISON OF DIRECT AND EXTERNAL MODULATION FOR CATV LIGHTWAVE TRANSMISSION AT 1.5pm WAVELENGTH

The use of a high-power 1 . 5 ~ DFB laser and a linearised Ti : LiNbO, Mach-Zehnder modulator as a transmitter in a CATV lightwave system is reported. The performance is compared with directly-modulated l.5pm-wavelength DFB lasers in 60channel transmission over 16 km of conventional singlemode fibre. The transmission of 52 high-frequency channels is demonstrated (450-750 MHz) in anticipation of...
