Photonic chip based tunable and reconfigurable narrowband microwave photonic filter using stimulated Brillouin scattering
Stimulated scattering modulation Nonlinear optics integrated optics Radio frequency photonics
2015/8/7
We report the first demonstration of a photonic chip based dynamically reconfigurable, widely tunable, narrow pass-band, high Q microwave photonic filter (MPF). We exploit stimulated Brillouin scatter...
Semiconductor Laser White Noise Suppression by Optical Filtering with Ultra-Narrowband FBG
Semiconductor lasers Fiber Bragg gratings
2015/5/21
The white frequency noise of semiconductor lasers is attenuated significantly by optical filtering with an ultra-narrowband fiber Bragg grating. This noise reduction will improve carrier phase estimat...
Optimisation of narrowband optical filters for 10 Gbit/s directly modulated laser transmitters
directly modulated laser optical filtering dispersion tolerance dispersion penalty
2011/5/6
Filtering of the chirped signal from a directly modulated laser with the narrowband optical filter
with a high roll-off allows to in-crease the dispersion tolerance of the transmitter substantially. ...
