We demonstrate that the use of an optimized bielectrode reflective semiconductor optical amplifier as remote modulator reduces the chirp therefore the penalties for transmission from 6 to 4.5 dB on
The chirp induced by saturated quantum dot SOA is carefully studied. It is demonstrated that circular dots allow for 50 km of transmission at 10 Gb/s, even upon saturation.
We experimentally demonstrate that the frequency chirp in sinusoidal-phase-modulated Ï/2 alternate-phase pulses can be greatly reduced by optical filtering.
The frequency chirp of semiconductor lasers of directed modulated laser is investigated.
A technique enabling 10 Gbps data to be directly modulated onto a monolithic sub-THz dual laser transmitter is proposed.
The spectral and modulation characteristics of injection locked distributed feedback lasers operating at 1.5micrometer wavelength have been investigated.
The small form factor chirp-managed laser (CML) source at 1550 nm was used in conjunction with postdetection electronic signal processing to successfully achieve transmission over 1200 km of nonzer
We demonstrate a simple way of generating chirped and alternate-chirp return-to-zero signals of various duty cycles by means of a sinusoidally driven dual-drive Mach-Zehnder modulator.
A new and simple chirped return-to-zero transmitter is proposed and successfully used in 8 x 10Gbit/s transmission over 2000km of standard singlemode fibre with 80km amplifier span.
We present a detailed analysis of positively and negatively chirped return-to-zero differential phase-shift keyed (CRZ- DPSK) signals that are generated using a single Mach-Zehnder modulator at the
