A Novel Coherent Digital Sweep Oscillator with Extremely Low Sweep Rates and Harmonic Distortion
Harmonic distortion Sweep rate Digital sweep oscillators Look-up-table Fractional addressing Interpolation methods
2010/12/8
A novel technique to efficiently increase the resolution of coherent digital sweep oscillators based on look-up-table (LUT) methods is proposed. The increase in resolution measured in terms of sweep r...
Analysis of the Density of Electron-Hole Pairs for Minimal Pump Energy in a Laser Diode with Coherent Feedback
Density of electron-hole pairs laser diode coherent feedback minimal pump energy
2010/12/9
The average value in the time domain of the density of electron-hole pairs in a semiconductor laser with coherent feedback is calculated under conditions of minimal pump energy. This value is found to...
A Brief Note on Coherent Feedback in Semiconductor Lasers
Coherent Feedback Semiconductor Lasers
2010/12/15
Some aspects on coherent feedback in a laser diode are investigated. In particular, weak optical feedback is considered in the context of the feedback-induced frequency shift. In addition, the Lang-Ko...
