We numerically investigate the thermal crosstalk effects in an integrated InP multiwavelength laser. The multiwavelength laser under investigation consists of a number of Distributed Bragg Reflector lasers and an Arrayed Waveguide Grating. Each laser generates a fixed wavelength and the Arrayed Waveguide Grating collects the emitted wavelengths leading all of them in a common output waveguide. Temperature distribution and heat flow are obtained through thermal simulations. Our model predicts the thermal crosstalk between lasers in relation to: injected current, distance between lasers and number of lasers. The aim of this paper is to define guidelines to design low thermal crosstalk multiwavelength lasers.
