Equivalent Circuit Of A Semiconductor Optical Amplifier Chip With The Bias Current Influence

Based on a diode-laser model, this paper presents the equivalent electrical circuit above and below the transparency condition for a chip (unpackaged) semiconductor optical amplifier. The modeling and parameters extraction were obtained as a function of the bias current, achieving good agreement between theoretical and experimental results in a wide frequency range, up to 40 GHz. © 2011 IEEE.852856Boers, P.M., Vlaardingerbroek, M.T., Danielsen, M., Dynamic behaviour of semiconductor lasers (1975) Electronics Letters, 11 (10), pp. 206-208. , May 15Mork, J., Mecozzi, A., Eisenstein, G., The modulation response of a semiconductor laser amplifier (1999) Selected Topics in Quantum Electronics, IEEE Journal of, 5 (3), pp. 851-860. , May/JunTucker, R.S., Pope, D.J., Microwave Circuit Models of Semiconductor Injection Lasers (1982) Microwave Symposium Digest, MTT-S International, 82 (1), pp. 104-106. , JunGallep, C.M., Conforti, E., Reduction of Semiconductor Optical Amplifier Switching Times by Pre-Impulse-Step Injected Current Technique (2002) IEEE Photonics Technology Letters, 14 (7), pp. 902-904Mork, J., Nielsen, M.L., Berg, T.W., The Dynamics of Semiconductor Optical Amplifiers: Modeling and Applications (2003) Optics and Photonics News, 14 (7), pp. 42-48Toazza, A.L., Guimaraes, M., Petersen, C.A.C., Gallep, C.M., Conforti, E., Experimental and theoretical analysis of packaging inductances and stray capacitances of a Semiconductor Optical Amplifier (2006) Telecommunications Symposium, 2006 International, pp. 63-66. , vol., no., 3-6 SeptTucker, R.S., Pope, D.J., Circuit modeling of the effect of diffusion on damping in a narrow-stripe semiconductor laser (1983) Quantum Electronics, IEEE Journal of, 19 (7), pp. 1179-1183. , JulTucker, R.S., Kaminow, I.P., High-frequency characteristics of directly modulated InGaAsP ridge waveguide and buried heterostructure lasers (1984) Journal of Lightwave Technology, 2 (4), pp. 385-393Katz, J., Margalit, S., Harder, C., Wilt, D., Yariv, A., The Intrinsic Electrical Equivalent Circuit of a Laser Diode (1981) IEEE J.
