چکیده

We propose and demonstrate a simple method to generate ultrawideband (UWB) pulses in the optical domain using a chirped intensity modulator and an asymmetric Mach-Zehnder interferometer (AMZI). Polarity- and shape-switchable UWB Gaussian monocycle, doublet, and triplet pulses with fractional bandwidths of 158%, 134%, and 100% and center frequencies of 6.52, 9.78, and 10.1 GHz are experimentally generated by controlling the dc bias of the intensity modulator and adjusting the polarization controller in the AMZI.

In this paper a method for digitally recording four quarter-reference-wave-holograms (by CCD) in a Mach-Zehnder interferometer setup, and reconstructing the object wave-front by numerical method is presented. The terms of direct transmission, auto-correlation and conjugate wave in the four wave reconstruction are cancelled out and only one original object wave is left after overlapping. Reconst...

Analysis and Improvement of Mach–Zehnder Modulator Linearity Performance for Chirped and Tunable Optical Carriers

Photonic systems that use a variable or chirped optical wavelength and a single Mach–Zehnder modulator have been analyzed to determine the relation between optical bandwidth and spur free dynamic range. A novel wavelength insensitive biasing technique is proposed which significantly reduces the second-order distortion and increases the optical bandwidth.
