Abstract

Generation of Optical pulses in order of picoseconds by modeling the Quantum Cascade Laser with two level rate equations and theoretical accounting of gain switching is reported.QCL is simulated with different inputs such as sinusoidal, tangential hyperbolic, square and trapezoidal. Analysis of parameters like FWHM, maximum power is done using the Golden Section Search and Parabolic Interpolation algorithms for maximum power and shortest FWHM. Sinusoidal input produce short pulse of 27.62ps, 49.2mW.Trapezoidal pulse generates 17ps, 122.1mW.Optical pulse of value 13.15ps, 178.3mW pertaining to tangential hyperbolic is obtained. An output pulse with maximum power is observed in tangential hyperbolic waveform. The shortest optical pulse is obtained with square pulse for power less than 0.5W.
