“…The external cavity semiconductor lasers (ECSLs) [1][2][3][4][5][6][7][8][9][10][11] have many advantages such as narrow line width, simple configuration, low cost and so on, where the fiber grating external cavity semiconductor lasers (FGECSLs) have received special attention in recent years due to its potential applications in coherent optical communication, DWDM systems, micro-opto-electro-mechanical systems etc. At present, there are several traditional approaches to study the FGECSLs.…”

Based on the coupled mode theory, the transfer matrix approach is presented to investigate the fiber grating external cavity semiconductor lasers (FGECSL). As a result, the P-I curve, the lasing wavelength and the side-mode-suppressionratio (SMSR) have been investigated numerically in detail. With the length of the fiber grating increasing, the reflection spectrum of FGECSL changes obviously, the threshold current and threshold carrier density decreases, the mode distribution is irregular, and the output spectrum becomes complex. Moreover, the optical bistablility is also observed.

A theoretical analysis of the optical feedback from external reflector influence on the Frequency response of GaAs/Al 0.45 Ga 0.55 As triple quantum well Quantum Cascade Laser emitting at (λ=9 µm) is presented. The employed theoretical model was based on Schrodinger equation. To demonstrate the effects of external cavity, many of the external cavity parameters were controlled such as the length of the external cavity, the proportion of optical feedback and the relative phase difference.
