Experimental verification of the effect of depletion-region modulation on photoconductance lifetime measurements

Extended criterion for the modulation instability

“…The ELC requires neither Ω s =ω 0 nor the polynomial expansion of β(ω). It is consistent with all results reported in [27][28][29][30][31][32][33][34][35][36][37][38][39][40].…”

“…which is independent on SVEA and NLSE. The phase matching condition was used to study MI at ZDF [27,28] and FWM instability [36][37][38].…”

“…Parameter β 3 affects neither MI domain nor increment [25,26]. MI at ZDF [27][28][29] where β 2 =0 occurs if β 4 <0. The competition of a small b ¹ 0 2 and β 4 may result in a new instability [30], the so-called four wave mixing (FWM) instability.…”

Subsideband generation and modulational instability lasing in a fiber soliton laser

“…26,27 To explain this difference, we emphasize that the subsidebands observed in our experiment are in fact results of modulational-instability lasing. 28,29 This is different from the modulational instabilities in optical fibers, where the instability spectral lines are generated at the modulational-instability gain peaks, which therefore have exactly the same wavelength shifts.…”

Highly stabilized millimeter-wave generation by using fiber-optic frequency-tunable comb generator

“…A wide range of discrete emission spectrum with the equifrequency interval of of the fiber-optic frequency comb generator is obtained by seeding the pump lightwave modulated with RF frequency into a dispersion-shifted single-mode fiber, so-called DSF. This is due to the nonlinear four-wave mixing in the DSF, which is distinct from the super continuum optical spectrum [14] and the modulational instability [15]. The tunability of the frequency interval is obtained by changing the seeded sideband frequency of the pump lightwave.…”
