Analysis of Modulation Response of a 450 nm True Blue Semiconductor Laser by Varying Differential Gain
Abstract: AbstractIn this work the analysis of modulation response of a 450 nm InGaN based multi-quantum well (MQW) true blue semiconductor laser have been presented. The internal designing of 450 nm blue laser has been done before. but the desired wavelength of 450 nm was obtained by adjusting the exact concentration of In0.211Ga0.789N/Al0.07Ga0.93N in this work. The effects on modulation response by varying the differential gain have been observed. Also, the …

Analysis of Saturation Power based on Device Structural Parameters of a 1550 nm Symmetrical MQW Semiconductor Optical Amplifier
Abstract: AbstractThis paper presents the effect of device structure parameters on the saturation power of a 1550 nm symmetrical Multi Quantum Well (MQW) Semiconductor Optical Amplifier (SOA) for a small signal amplifier gain of 30 dB. Expressions are given to assess this dependency and the results indicate that saturation power decreases with the increase of the number of wells, well thickness and length but increases with the increase of barrier thickness. …

Fourier Transform and Optical Analogy of the Sharply Pulsed E.P. Seismic Signals Propagating Through The Core of Earth
Abstract: AbstractLike light rays that encounter a water surface, seismic rays are governed by the laws of reflection and refraction. Eventually, there exist wave properties within these. Due to rigorous BIS (breakdown of integrated system) processes, severe consequences like earthquakes occur. The waves that are generated in an earthquake down into the interior of the earth are called earthquake waves or seismic waves. In the present paper, the author will consider …
