Novel photonic radio-frequency Arbitrary Waveform generation based on photonic digital-to-analog conversion with pulse carving
2015 Conference on Lasers and Electro-Optics (CLEO), 2015Co-Authors: Jinxin Liao, Shangyuan Li, Hanyi Zhang, Boyu Chen, Xiao Yang, Xiaoping Zheng, Bingkun ZhouAbstract:We firstly propose a photonic radio-frequency Arbitrary Waveform Generator based on photonic digital-to-analog conversion with pulse carving, and demonstrate 10GS/s 4-bit resolution Arbitrary Waveform generations with 15GHz and 30GHz up-converting.

a time domain photonic Arbitrary Waveform Generator
Optics Express, 2012Co-Authors: Jinxin Liao, Hanyi Zhang, Xiaoping Zheng, He Wen, Bingkun ZhouAbstract:A time domain photonic Arbitrary Waveform Generator (PAWG) scheme based on multi-wavelength optical differential quadrature phase shift keying modulation in combination with differential detection is proposed and experimentally demonstrated. The time domain method shows advantages of large time-bandwidth product, good flexibility, fast Waveform refreshing rate, and high Waveform quality over the frequency domain method. In contrast with other proposed time domain PAWGs or photonic digital-to-analog converters, our PAWG proposal shows a greater dynamic range and a larger noise margin due to its bipolar output, and possesses good scalabilities both in resolution and sampling rate. Assisted with the integration technology, this PAWG presents a good prospect for broad range practical applications in future.

optical Arbitrary Waveform Generator applicable to pulse generation and chromatic dispersion compensation of a remote uwb over fiber system
Optics Express, 2011Co-Authors: Xin Zhou, Xiaoping Zheng, Hanyi Zhang, Bingkun ZhouAbstract:Optical Arbitrary Waveform Generator (OAWG), which can generate pre-distorted ultra-wideband (UWB) pulses to tolerate the chromatic dispersion (CD) of the fiber without any other CD compensation solutions, provides a good solution for the UWB over fiber system. In our paper, we experimentally demonstrate a new OAWG scheme based on multiple incoherent continuous wave lights by double side band with suppressed carrier (DSB-SC) modulation. UWB Gaussian monocycle and doublet pulses are generated and the chromatic dispersion of 20-km, 50-km and 100-km single-mode fiber (SMF) are compensated by the OAWG system without any other CD compensation solutions.

multichannel radio frequency Arbitrary Waveform generation based on multiwavelength comb switching and 2 d line by line pulse shaping
IEEE Photonics Technology Letters, 2012Co-Authors: Victor Torrescompany, Andrew J Metcalf, Daniel E Leaird, Andrew M WeinerAbstract:We demonstrate a multichannel time-multiplexed radio-frequency Arbitrary Waveform Generator. The system combines a switching scheme of multiwavelength optical frequency combs with a novel 2-D line-by-line pulse shaper featuring broad bandwidth operation over large temporal windows. Switching times within a clock period of 200 ps among the four channels is successfully achieved. With finer pulse shaper resolution, the number of channels can be scaled up without increasing the number of switching components.

nanosecond pulse shaping at 780 nm with fiber based electro optical modulators and a double pass tapered amplifier
Optics Express, 2016Co-Authors: C E Rogers, P L GouldAbstract:We describe a system for generating frequency-chirped and amplitude-shaped pulses on time scales from sub-nanosecond to ten nanoseconds. The system starts with cw diode-laser light at 780 nm and utilizes fiber-based electro-optical phase and intensity modulators, driven by an Arbitrary Waveform Generator, to generate the shaped pulses. These pulses are subsequently amplified to several hundred mW with a tapered amplifier in a delayed double-pass configuration. Frequency chirps up to 5 GHz in 2 ns and pulse widths as short as 0.15 ns have been realized.
