New dynamic model for multimode chirp in DFB semiconductor lasers - Optoelectronics [see also IEE Proceedings-Optoelectronics], IEE Proceedings J

چکیده
A new technique for modelling the dynamic spectral characteristics of DFB semiconductor lasers above threshold, which is based on the transmission-line laser model, is described. This includes the effects of index carrier dependence and longitudinal index variations. The timedomain responses and spectra of quarter-wave shifted grating devices are compared with unshifted devices under transient conditions. 1

New dynamic multimode model for external cavity semiconductor lasers - Optoelectronics [see also IEE Proceedings-Optoelectronics], IEE Proceedings J
1 Abstract: A new, dynamic, time-domain, numerical model for external cavity lasers, based on the transmission-line laser model (TLLM), is introduced. This is able to show the evolution of spectra from large-signal modulated devices, even when the modulation pulsewidth is less than the external cavity round-trip delay. The model is demonstrated using short and long dispersionless cavities. Resu...
متن کاملAnalysis of direct-discrimination of FSK modulated optical signal using injection-locked DFB lasers - Optoelectronics [see also IEE Proceedings-Optoelectronics], IEE Proceedings J
Direct discrimination of FM and FSK optical signals using injection-locked DFB semiconductor lasers is analysed. The demodulation eficiency is found to be independent of the optical injection level in the steady state. However, the optical injection level is important in determining the dynamic response. There exists an optimum optical injection rate to achieve the highest demodulation speed. T...
متن کاملStatistical analysis of nonlinear optical amplifier in high saturation - Optoelectronics [see also IEE Proceedings-Optoelectronics], IEE Proceedings J
In the work, analytic expressions describing the behaviour of a strongly saturated nonlinear optical amplifier are deduced. These expressions make possible the calculation of the mean and variance of the amplified light photon number. Results are compared with those obtained by the numerical resolution of the photon density matrix equation, and good accordance is observed in the strong saturati...
متن کاملMain resonances in directly modulated semiconductor lasers: effect of spontaneous emission and gain - Optoelectronics, IEE Proceedings-
Boundaries for the primary saddle-node bifurcations related to the main resonances in pump-modulated laser diodes are obtained via numerical simulation. The model explicitly contains the gain saturation and spontaneous emission terms and the authors focus on the effect that these terms have on the large signal modulation regime. It is found that the spontaneous emission term strongly modifies t...
متن کاملSEMICONDUCTOR AND INTEGRATED OPTOELECTRONICS (SIOE) Optimisation of distributed feedback laser biosensors
A new integrated optical sensor chip is proposed, based on a modified distributedfeedback (DFB) semiconductor laser. The semiconductor layers of different refractive indices that comprise a laser form the basis of a waveguide sensor, where changes in the refractive index of material at the surface are sensed via changes in the evanescent field of the lasing mode. In DFB lasers, laser oscillatio...
