Investigation of Intensity and Phase FeedbackEffects on the Relative Intensity Noise in BlueLaser Diodes under High Frequency Modulation

摘要

The quantum noises in typical Blu-ray laser diodes have been modeled after thequantum Langevin formalism into three level rate equations. The required material parametershave also been extracted by using the multiband Hamiltonian for strained wurtzite crystals. Theresults reveal the existence of an optimum current modulation level to minimize the relativeintensity noise.
