Abstract
Diffraction and truncation effects are the important effects that appear due to miniaturization of the external cavity tunable laser source ECTL. So in this paper presents the diffraction effects on the performance of an dual external cavity tunable laser source, whose external cavities are constructed by micro electro mechanical systems (MEMS). One of the main problems in these structures is the optical diffraction as the emitting surface of the laser diode is usually quite limited in the transverse directions. The emitted beam diffracts rapidly in the air and only a small amount of light is coupled back to the source that usually limits the tuning range of the source. The simulation results have shown that dual external cavity has large tuning range than single external cavity by using new expression. It is shown that multiple reflection has significant effect in our model. To get a better engineering for the dual ECTL dimensions, diffraction and Truncation effects must be taken into account.
