| Abstract(in English) | To realize an optical packet switch operating with high speed and low power consumption, we have investigated an optical digital-to-analog converter (ODAC) type label processor. It converts serial bits of label into a single pulse with multi-level amplitude. So multiple label signals can be recognized by one step process, and reduction of power consumption and the number of optical devices can be expected. Moreover, the integration of the ODAC on semiconductors is important for downsizing. We have reported 2-bit digital-to-analog conversion with a semiconductor integrated ODAC. However, output power fluctuation with phase difference, frequency chirping and extinction ratio are technical issues. In this report, we estimate the influence of chirping in a semiconductor ODAC which causes output power fluctuation, and analyze the operation tolerance of phase, chirping, intensity, and extinction ratio of an ODAC by calculating the BER of output signal. The results indicate the operable conditions of label recognition with the semiconductor ODAC. |
