Efficiency-enhanced soliton optical parametric amplifier
We show that the pump–to–signal power conversion efficiency of parametric chirped-pulse amplifiers made with periodically poled materials operating with multicolor spatial solitons can be significantly enhanced by employing engineered quasi-phase-matching gratings. Applications include compact sources of high-energy ultrashort pulses in diffraction-limited high-quality beams. © 2002 Optical Soc...
متن کاملBroadly tunable carrier envelope phase stable optical parametric amplifier pumped by a monolithic ytterbium fiber amplifier.
In an effort to develop a robust and efficient front end for a chirped-pulse parametric amplification chain, we demonstrate a broadband difference-frequency converter driven by a monolithic femtosecond Yb-doped-fiber amplifier and emitting carrier-envelope-offset-free pulses with the energy of tens of nanojoules tunable in the wavelength range from 1200 nm to beyond 2 mum. Next to providing the...
متن کاملQuadrature demultiplexing using a degenerate vector parametric amplifier.
We report on quadrature demultiplexing of a quadrature phase-shift keying (QPSK) signal into two cross-polarized binary phase-shift keying (BPSK) signals with negligible penalty at bit-error rate (BER) equal to 10(-9). The all-optical quadrature demultiplexing is achieved using a degenerate vector parametric amplifier operating in phase-insensitive mode. We also propose and demonstrate the use ...
متن کاملDiscrete Time Parametric Amplifier based Dynamic clocked Comparator
A low gain discrete-time parametric amplifier (DTPA) [1] can sample, hold and amplify an input signal using the MOS varactor properties. The DTPA consumes ultra low power with very low noise. A DTPA exhibits a common-mode voltage shift at the output terminal. To nullify this common-mode voltage shift, [2] has proposed a complementary parametric amplifier (CDTPA). In a CDTPA, an nMOSDTPA and a p...
