Modulation instabilities in two-core optical fibers

Abstract: Modulation instability (MI) of cw states of a two-core fiber, incorporating the effects of coupling-coefficient dispersion (CCD), is studied by solving a pair of generalized, linearly coupled nonlinear Schrödinger equations. CCD refers to the property that the coupling coefficient depends on the optical wavelength, and earlier studies of MI do not account for this physics. CCD does not seriously affect the symmetric/antisymmetric cw, but can drastically modify the MI of the asymmetric state. Generally, new MI … Show more

“…The phenomenon of periodic optical power transfer between the two cores along a TCF [19] is widely used in many practical fiber-optic devices. Various aspects of the MI in a TCF have been studied [20][21][22]. The MI characteristics of the symmetric and antisymmetric CW states in a TCF are qualitatively similar to those in a conventional single-core fiber [20].…”

“…On the other hand, the spontaneous symmetry breaking in linearly coupled systems gives rise to asymmetric CW states in a TCF [23], which makes its MI characteristics qualitatively different from those of a single-core fiber [21]. In particular, the dispersion (or wavelength dependence) of the coupling coefficient between the two cores can drastically modify the MI bands of the asymmetric states in both the anomalous and normal dispersion regimes [22].…”

“…Among different types of fiber lasers, dual-core ring lasers have been receiving a widespread interest owing to their numerous applications in photonics [13][14][15][16][17][18][19]. Nonlinear directional couplers (NLDC) are one of important components of integrated optical devices and they deliver quite a few lightwave applications including switching (bright and dark) [20][21][22][23][24][25][26][27], logical operations [28,29], ultra-short pulse generation through modulational instability [30][31][32][33][34][35], and amplifiers [36,37]. In particular, Winful and Walton have proven that the asymmetric dual core fibers can act as a passive mode-locking fiber laser provided one of the dual-cores must be doped with rare earth-elements like erbium while the other core must be a passive one [3].…”
