Abstract

Temperature controlling is important for optoelectronic device's stable and reliable working, especially in poor circumstance or for long time. This article represents an active temperature control system used to control the temperature of a tunable narrow-linewidth external cavity semiconductor laser. A double deck cooling structure controlled by an intelligent driver is reported and the feature of the system is investigated.
