Nondegenerate Four-Wave Mixing in a Dual-Mode Injection-Locked InAs/InP(100) Nanostructure Laser

Abstract

International audienceThe nondegenerate four-wave mixing (NDFWM) characteristics in a quantum-dot Fabry-Perot laser are investigated, employing the dual-mode injection-locking technique. The solitary laser features two lasing peaks, which provides the possibility for efficient FWM generation. Under optical injection, the NDFWM is operated up to a detuning range of 1.7 THz with a low injection ratio of 0.42. The normalized conversion efficiency (NCE) and the side-mode suppression ratio (SMSR) with respect to the converted signal are analyzed. The highest NCE of 17 dB associated with a SMSR of 20.3 dB is achieved at detuning of 110 GHz

Significantly Enhanced Third Harmonic Generation Using Individual Au Nanorods Coated With Gain Materials

“…The locally enhanced electromagnetic field near the plasmonic nanostructures can be used in various applications ranging from solar cells [1] to bio-probe based imaging [2], surface enhanced Raman scattering (SERS) [3], and cancer therapy [4]. In addition to the enhanced the local electronic field, researchers are currently devoting more attention to optical frequency upconversion based on LSPR, e.g., second harmonic generation [5]- [14], third harmonic generation (THG) [15]- [20], and four-wave mixing [21]- [23]. These optical upconversion effects by using LSPR can be widely applied in various fields.…”

Nonlinear conversion efficiency of InAs/InP nanostructured Fabry-Perot lasers

“…On the other hand, a laser cavity exhibits a reduced ASE through resonance and can thus provide a higher optical signalto-noise ratio (OSNR) with respect to SOAs. To this end, this paper aims at extending the study of NDFWM [11] to semiconductor laser diodes in order to show that further improvements in the NDFWM generation as well as to a higher optical signal-to-noise ratio (OSNR) can be achieved. Although the use of a DFB laser is simpler, given that its single lasing peak can be employed as pump wave, it has to be stressed that in this case the nonlinear efficiency remains strongly dependent on some complex additional DFB features such as the strength of the grating coefficient, facet phase effects or spatial hole burning, which are somewhat difficult to control from device to device [7][12] [13].…”

Non-degenerate four-wave mixing in an optically injection-locked InAs/InP quantum dot Fabry–Perot laser

“…11,16 To this end, in our previous work, the dual OIL configuration was used for generating efficient NDWFM in a U-band InAs/InP FP laser. 17 In this work, the dual injection scheme is reemployed with a 1550 nm InAs/InP QD FP laser operating within the stable-locking range. The NCE is found to vary from À25 dB to À60 dB for frequency detunings ranging from a few tens of GHz to several THz.…”
