WebPhase-inserted fiber gratings (PI-FGs) refer to those gratings where there exist a number of the phase-shifts (spatial spacing) among different sections (or local periods) of the gratings themselves. All the PI-FGs developed to date can mainly be divided into three categories: phase-shifted gratings, phase-only sampled gratings, and phase-modulated gratings, of …

Did you know?
WebOptical feedback from an external reflector is a wellknown mechanism for inducing dynamical effects in semiconductor lasers. The behavior that results depends on many factors, such as the laser architecture and operating conditions, the external cavity length and configuration, and the strength of the feedback. WebSep 22, 2015 · Abstract: We theoretically analyze the use of fully integrated high-Q ring cavities (intrinsic Q ~ 1 million) with widely tunable semiconductor lasers to realize narrow linewidth lasers. Different configurations are studied, including cases where the high-Q cavity is external to the laser cavity and provides filtered optical feedback to the laser …
WebSep 10, 2024 · Wall-stabilized arcs dominated by nozzle–ablation are key elements of self-blast circuit breakers. In the present study, high-current arcs were investigated using a model circuit breaker (MCB) in CO2 as a gas alternative to SF6 (gas sulfur hexafluoride) and in addition a long polytetrafluoroethylene nozzle under ambient conditions for … WebA narrow-linewidth single-frequency photonic-microwave-generation scheme using an optically injected semiconductor laser with a filtered optical feedback has been proposed. The filtered feedback comes from a single feedback loop, which includes a narrow bandpass filter. With the filtered feedback, the linewidth of the generated microwave …
WebThe behavior of a semiconductor laser subject to filtered optical feedback is studied in dependence on the width of the filter. Of special interest are pure frequency oscillations where the laser intensity is practically constant. We show that frequency oscillations are stable in a large region of intermediate values of the filter width, where the dispersion of … WebFeb 1, 2004 · Filtered optical feedback is a much simpler approach towards perturbing both intensity and phase dynamics. Optical feedback using band-pass filter was demonstrated by Fischer et al. [47]. Band ...
WebMar 10, 2024 · Upon a further increase in the optical feedback ratio, the linewidth increases again. This variation trend is different from that in the DFB laser and VCSEL [28,35] but is similar to that in the DFB laser with filter feedback at some frequency detuning . The relationship between the phase noise and the feedback ratio is similar to that of the ...
