Chirped gratings can be readily implemented in uniform-period waveguide Bragg gratings (WBGs) by adopting a tapered profile in the core patterning process. Based on our analysis, we have demonstrated that controlled linear chirps can be generated in WBGs with specifically designed core-taper profiles. By virtue of our established design and fabrication techniques, the measured center wavelengths,...
Wireless personal area networks (WPAN) systems for the communication in the indoor environment have been developed according to the growth of the ubiquitous technology. IEEE 802.15.4a is a standard which describes the indoor communication systems for the ultra-low complexity and power consumption. Implementation of PHY for IEEE 802.15.4a employs ultra-wide band (UWB) technologies which have the advantage...
Chirped waveguide Bragg gratings are fabricated by tapering the width of the core involving uniform grating. A residual dispersion (+170 ps/nm) in a 40-Gb/s transmission system is compensated by adjusting temperature gradients in the waveguide.
