Power-Efficient Photonic BPSK Coded Ultrawideband Signal Generation
Fiber optics optical communications Radio frequency photonics
2015/5/22
We experimentally demonstrate a power-efficient BPSK coded ultrawideband(UWB) signal generator. The 2.5 Gb/s BPSK coded signal is achieved through optical switching based on two intensity modulators d...
Novel Optical Generation of Ultrawideband (UWB) Signals Using Quadratic Nonlinear Interactions Seeded By Normal/Dark Pulses
Optical Ultrawideband (UWB) Quadratic Nonlinear Seeded Normal/Dark Pulses
2015/7/17
We report two approaches to generate optical ultrawideband (UWB) signals using quadratic nonlinear interactions in periodically poled lithium niobate (PPLN) seeded by either normal or dark pulses. Pai...
