Modelocked semiconductor lasers are used widely in applications requiring picosecond optical pulses.
We study the frequency chirp properties of Graphene-on- Silicon electro-absorption modulators (EAMs).
Dynamic line broadening (chirping) of a single-frequency coupled- cavity semiconductor laser under direct current modulation is analyzed theoretically using a set of generalized rate equations.
Static and dynamic properties of InP-based Quantum Dashes of 1.55μm directly modulated lasers are reported.
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.
