Probability distribution of phase-induced intensity noise generated by distributed-feedback lasers.
Highly non-Gaussian, short-tailed photocurrent distributions due to laser-phase-induced intensity noise have been observed in fiber-optic systems employing distributed-feedback lasers and wideband receivers. This behavior, which has implications for the correct prediction of performance in systems containing intentional or spurious interferometers, results from the cosinusoidal nonlinearity int...

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
Intensity and phase noise in microcavity surface-emitting semiconductor lasers
The noise characteristics of vertical-cavity surface-emitting (VCSE) lasers are studied by using the Langevin rate equations modified suitably to include the enhanced spontaneous emission occurring in such microcavity lasers. The intensity and frequency noise spectra show the effects induced by suppression of relaxation oscillations. However, such a suppression depends on the output power as we...
متن کاملFeedback-induced chaos and intensity-noise enhancement in vertical-cavity surface-emitting lasers
We investigate numerically the effects of optical feedback on the intensity noise of vertical-cavity surfaceemitting lasers (VCSEL’s) under single-mode and two-mode operations. Our model includes transverse effects such as carrier diffusion and spatial hole-burning. Results indicate that the relative-intensity noise is relatively unaffected at low feedback levels except for a narrowing and enha...
متن کاملDesign of phase-shifted hybrid silicon distributed feedback lasers.
We present data on the design and performance analysis of phase shifted distributed feedback (DFB) lasers on the hybrid silicon platform. The lasing wavelength for various input currents and temperatures, for devices with standard quarter-wavelength, 60 μm and 120 μm-long phase shift are compared for mode stability and output power. The pros and cons of including a large phase shift region in t...
