“…Usually ρ is about 10 −3 for an XFEL. The line-by-line laser pulse shaping technique developed recently (Jiang et al, 2007) might be helpful in the future to synthesize a uniform enough laser-field envelope containing an optical carrier for the laser undulator.…”

The use of infrared lasers to power optical-scale lithographically fabricated particle accelerators is a developing area of research that has garnered increasing interest in recent years. We review the physics and technology of this approach, which we refer to as dielectric laser acceleration (DLA). In the DLA scheme operating at typical laser pulse lengths of 0.1 to 1 ps, the laser damage fluences for robust dielectric materials correspond to peak surface electric fields in the GV/m regime. The corresponding accelerating field enhancement represents a potential reduction in active length of the accelerator between 1 and 2 orders of magnitude. Power sources for DLA-based accelerators (lasers) are less costly than microwave sources (klystrons) for equivalent average power levels due to wider availability and private sector investment. Due to the high laser-to-particle coupling efficiency, required pulse energies are consistent with tabletop microJoule class lasers. Combined with the very high (MHz) repetition rates these lasers can provide, the DLA approach appears promising for a variety of applications, including future high energy physics colliders, compact light sources, and portable medical scanners and radiative therapy machines.

“…Knowledge of the phase relationship between the various spectral lines is important both from a fundamental perspective and to allow manipulation of the time domain behavior, e.g., through programmable optical pulse shaping [20]. Recently, increasing interest has arisen in line-by-line shaping, in which the individual lines of a frequency comb are resolved and independently controlled [21][22][23][24][25]. Also termed optical arbitrary waveform generation, pulse shaping at the individual line level offers significant opportunities for impact both in technology (e.g., telecommunications, lidar) and ultrafast optical science (e.g., coherent control and spectroscopy).…”

We report, for the first time to the best of our knowledge, spectral phase characterization and line-by-line pulse shaping of an optical frequency comb generated by nonlinear wave mixing in a microring resonator. Through programmable pulse shaping the comb is compressed into a train of near-transform-limited pulses of ≈ 300 fs duration (intensity full width half maximum) at 595 GHz repetition rate. An additional, simple example of optical arbitrary waveform generation is presented. The ability to characterize and then stably compress the frequency comb provides new data on the stability of the spectral phase and

“…Another powerful solution is to further process the externally modulated CW laser frequency combs using spectral line-by-line pulse shaping [45]. Compared with passive AWG, the line-by-line shaper is an adaptive setup and can therefore offer complete gray-level control in terms of optical phase, amplitude and even polarization.…”

T he most useful wireless communication band is located in the frequency range of 0.3-3.5 GHz for reasons of compact antenna size, low propagation loss and good penetration through buildings [1]. However, wireless carrier frequencies are being pushed higher due to emerging high-bandwidth applications, which include next-generation smart cell phones [1] and wireless linking for three-dimensional super high-definition television [2]. As a result, the millimeter-wave (MMW) bands at 60 (V-band), 120 (D-band) and even higher than 300 GHz are beginning to attract attention due to their 'unlicensed' usage [2][3][4][5][6][7][8].Several key front-end components have been developed employing the already mature silicon-based complementary metal-oxide-semiconductor (CMOS) integrated-circuit (IC) technology for wireless communication in the V (50-75 GHz) and W (75-110 GHz) bands or even higher operating frequencies for wireless communication [9]. Recently, a 60 GHz CMOS transceiver module [10] and system comprised of antennas, 60 GHz power amplifiers, local oscillators and baseband ICs has been commercially developed by SiBEAM (USA). In addition, advanced InP-based high electron mobility transistors (InP-HEMTs) and heterojunction bipolar transistors have been used to develop some high-speed ICs and key components that operate at 125 GHz [11,12] or greater than 300 GHz [13,14] for >1 Gbit s -1 wireless communication systems.However, MMW signals suffer substantial propagation loss in free space [8]. This problem and their inherent straight-line path of propagation affect connections and synchronization between the different parts of the whole communication system [15]. A promising solution to overcome this problem is the radio-over-fiber (RoF) technique [3,4,16,17], in which the MMW local-oscillator signal and data are both distributed through a low-loss optical fiber and only radiated over the last mile to the end user. Figure 1 shows a schematic representation of this approach, illustrating the motivation and working principles of two MMW-over-fiber communication systems. Figure 1(a) shows the additional electrical-to-optical (E-O) and optical-to-electrical (O-E) conversion processes used in the central office and base station, respectively. The optical MMW signal is distributed remotely through a low-loss fiber from the central office to several base stations, effectively eliminating the huge propagation loss of the MMW signal that occurs in an electrical transmission line or free space.
