Generation and delivery of 1-ps optical pulses with ultrahigh repetition-rates over 25-km single mode fiber by a spectral line-by-line pulse shaper

Abstract

A spectral line-by-line pulse shaper is used to experimentally generate and deliver ~1 ps optical pulses of 31~124 GHz repetition-rates over 25.33 km single-mode fiber without dispersion-compensating fiber. The correlation of such delivery capability to temporal Talbot effect is experimentally demonstrated. Incorporating shaper periodic phase control, the repetition-rates of these~1 ps optical pulses are further multiplied up to 496 GHz and delivered over 25.33 km single-mode fiber.

Coherence revivals in two-photon frequency combs

“…Considering the recently reported fourfold analogy [27] that connects the space-time and quantum-classical domains and recalling that similar Talbot phenomena have been reported with two-photon [21] as well as with classical pseudothermal light [28,29], it is not difficult to envision a similar situation with classical statistically stationary Gaussian light. On the other hand, in the context of classical frequency combs, it has recently been proposed that this effect can be used to transmit frequency standards through optical fibers [30]. Taking into account the facts that two-photon frequency combs may be produced in compact microresonators [15] and these can be locked to an external reference [31], the results presented in this paper open exciting possibilities to remotely transfer frequency standards embedded on ultracompact quantum light sources while circumventing the need for dispersion cancellation.…”

Millimeter-wave photonic wireless links for very high data rate communication

“…Utilizing this setup, ~1 ps optical pulse trains with 31-496 GHz repetition rates suitable for remote high-modulation-depth photonic MMW generation have been demonstrated [48]. Compared with the use of pure optical sinusoidal waveforms as the photonic MMW source, short optical pulse excitation could offer a ~7 dB enhancement in the resulting MMW power given the same average operation photocurrent.…”

“…In addition, a higher maximum saturation current is obtained due to reduced device heating [22]. Furthermore, the line-by-line shaper can simultaneously provide the dispersion pre-compensation required for delivering short optical pulses for remote (>25 km) MMW signal generation without the need for additional dispersion management within the fiber link [48].…”

“…A thin p-type In 0.52 Al 0. 48 As charge layer in the InP-based collector layer experiences most of the externally applied electric field due to the higher breakdown field compared with that of InP. Based on equation (1), the higher electron drift velocity in the NBUTC photodiode suggests that these devices could offer superior SCBP performance compared with UTC photodiodes.…”

Enhanced Performance of Narrowband Millimeter-Wave Generation Using Shaped-Pulse-Excited Photonic Transmitters

“…Optical pulses from one branch of the fiber laser enter the pulse shaper from 1041-1135/$26.00 © 2011 IEEE a circulator through a polarizing beam splitter. Individual frequency components of the input pulses are diffracted by an 1100 l/mm grating and collimated by a 500 mm focal length lens onto the back focal plane of the lens, where a 640-channel liquid crystal modulator (LCM, CRI SLM-640-D-NM) and a mirror are located [8]. The LCM functions as a reconfigurable slit mask that selects a number of specific wavelengths of a fixed spectral width.…”
