Abstract :
A theoretical investigation of a novel multiwavelength laser diode based on cascading of distributed feedback lasers is presented with consideration of the optical and the thermal-induced interactions among the different lasing sections. The design criteria and conditions for stable continuous-wave operation are established by way of simulation. The possibility and mechanism for short pulse generation as a result of mode beating are demonstrated and discussed.
