摘　　要：The temperature characteristics of monolithically integrated wavelength-selectable light sources are experimentally investigated.The wavelength-selectable light sources consist of four distributed feedback(DFB)lasers,a multimode interferometer coupler,and a semiconductor optical amplifier.The oscillating wavelength of the DFB laser could be modulated by adjusting the device operating temperature.A wavelength range covering over 8.0 nm is obtained with stable single-mode operation by selecting the appropriate laser and chip temperature.The thermal crosstalk caused by the lateral heat spreading between lasers operating simultaneously is evaluated by oscillating-wavelength shift.The thermal crosstalk approximately decreases exponentially as the increasing distance between lasers.
