Abstract

In this paper, the effect of external optical feedback (EOF) on the turn-on time delay (ton) of uncooled semiconductor laser diode (SLD) is investigated theoretically. The effects temperature of operation (T) and EOF on ton are calculated according to their effect on threshold carrier density (Nth). The temperature dependence (TD) of Nth is calculated according to the TD of laser cavity parameters and not by the well-known Parkove relationship. Simulation results show that ton increases as T increases due to increasing of Nth. In addition, ton decreases as external reflectivity (rext) increases when the phase of reflected light is coherent. While at incoherent reflected light, ton increases sharply around specified value of r ext where this leads to inoperable case for SLD.
