Abstract
This paper presents a method to evaluate the impact of temperature characteristics on vertical cavity surface emitting laser (VCSEL) module. As one of the core modules in the optical communication system, the performance of VCSEL strongly influences the communication quality of the high-speed optical communication system. However, it is difficult to directly analyze the temperature change of VCSEL. In order to solve this problem, batches of laser sources have been integrated into the optical communication module, the physical properties of the laser beams then can be easily measured at different temperatures (low temperature −5 °C, room temperature 25 °C and high temperature 70 °C). By analyzing the wavelength, ext. ratio and the margin of eye diagram of these laser beams, we calculate the percentage value which referrers to an engineering experience standard value as the evaluator, to describe the quality of the optical communication system. The performance of communication quality is evaluated under different parameters, including amplitude, emphasis, mode and bias etc. Several tests have been preceded which all obtained the satisfactory results.
