Abstract : Two Section Single Cavity semiconductor lasers have received a lot of attention with regard to being suitable sources for coherent transmitters or as local oscillators in coherent fiber-optic systems, where the tuning and FM response of such lasers is important. The two sections are driven by currents I1 and I2 which are independent but the resulting current densities interact optoelectronically. TSSC Fabry-Perot Lasers exhibit contours of constant power in the I1,I2 plane and whose threshold contour closely resembles the non-linearity typical of electrical multiplexers.
