Abstract
Optical methods for different type ultra-wideband (UWB) pulse
generation based on cross-polarization modulation (CPM) are proposed and demonstrated
in this paper. Two polarity-reverse pulses can be obtained by CPM and birefringence
time delay to form a monocycle pulse. A semiconductor optical amplifier (SOA)
is placed after the monocycle pulse process for doublet pulse generation.
These two kinds of pulses can be employed in single-band impulse radio UWB
(IR-UWB) systems. Two kinds of multi-band UWB pulses can be generated based
on monocycle pulse train with proper apodization profiles, realized by hybrid
photonic microwave filter and synchronous polarization modulation respectively.
Experimental results show that these pulses can be used in multi-band UWB
(MB-UWB) over fiber systems.
