“…stimulated, three and four wave mixing processes are a close relative of the spontaneous four wave mixing process studied in this paper so that our discussion, including the physics of parity and OAM conservation, of course is related to the similar effects observed classically [29]. In particular, recent work has addressed these issues for stimulated four wave mixing [30,31]. The quantum-mechanical treatment presented here is aimed at enabling the design of a new generation of fiber-based photon pair sources with hybrid entanglement in frequency and in transverse mode.…”

We present a theoretical and experimental study of the generation of photon pairs through the process of spontaneous four wave mixing (SFWM) in a few-mode, birefringent fiber. Under these conditions, multiple SFWM processes are in fact possible, each associated with a different combination of transverse modes for the four waves involved. We show that in the weakly guiding regime, for which the propagation modes may be well approximated by linearly polarized modes, the departure from circular symmetry due to the fiber birefringence translates into conservation rules which retain elements from azimuthal and rectangular symmetries: both OAM and parity must be conserved for a process to be viable. We have implemented a SFWM source based on a "bow-tie" birefringent fiber, and have measured for a collection of pump wavelengths the SFWM spectra of each of the signal and idler photons in coincidence with its partner photon. We have used this information, together with knowledge of the transverse modes into which the signal and idler photons are emitted, as input for a genetic algorithm which accomplishes two tasks: i) the identification of the particular SFWM processes which are present in the source, and ii) the characterization of the fiber used.

“…FWM is another nonlinear optical effect that has been used to perform IFM for microwave sensing applications [49][50][51]. Simultaneous wavelength conversion of two optical signals based on FWM has been demonstrated using the MSND [41]. As such, we can also expect to perform simultaneous IFM for at least two microwave signals.…”

“…Each of the modes can then be used to process a different signal; as such, a single multimode waveguide can support parallel (simultaneous) multi-channel operation, i.e., spatial modes are utilized rather than a dedicated nonlinear waveguide per processed signal. For example, by harnessing nonlinear optics based on mode selectivity, Ding et al demonstrated simultaneous four wave mixing (FWM)-based wavelength conversion of two wavelength channels [41] while we achieved simultaneous regenerative wavelength conversion of two wavelength channels using XPM [42]. Since photonic implementation of RFSA is based on XPM, we consider exploiting mode selective nonlinear optics to characterize simultaneously multiple ultrahigh repetition rate optical signals [43].…”

Microwave photonic (MWP) systems exploit the advantages of photonics, especially with regards to ultrabroad bandwidth and adaptability, features that are significantly more challenging to obtain in the electronic domain. Thus, MWP systems can be used to realize a number of microwave signal processing functions including, amongst others, waveform generation and radio-frequency spectrum analysis (RFSA). In this paper, we review recent results on fiber and integrated approaches for simultaneous generation of multiple chirped microwave waveforms as well as multi-channel RFSA of ultrahigh repetition optical rate pulse trains.

“…The most studied technology is wavelength conversion [4][5][6] via degenerate FWM, which requires highly nonlinear silicon waveguides with engineered group-velocity dispersion (GVD). More specifically, efficient FWM takes place when phase matching is satisfied, which requires an anomalous GVD to cancel the Kerr-induced nonlinear phase shift [7].…”

Abstract:We propose a silicon waveguide structure employing silica-filled vertical-dual slots for broadband wavelength conversion, which can be fabricated using simple silicon-on-insulator technology. We demonstrate group-velocity dispersion tailoring by varying the width of the core, the slots and the side strips, and put forward a method to achieve spectrally-flattened near-zero anomalous group-velocity dispersion at telecom wavelengths. A proposed structure provides a group-velocity dispersion parameter β 2 of −60 ps 2 /km with an effective mode area A eff of 0.075 µm 2 at 1550 nm. This structure is predicted to significantly broaden the bandwidth of wavelength conversion via four-wave mixing, which is validated with experimentally measured 3 dB bandwidth of 76 nm.
