Abstract:
A method of precisely estimating the /spl alpha/ factor for electroabsorption-type optical-intensity modulators is described. This method takes into account the nonlinearity of extinction-ratio characteristics. It yields smaller /spl alpha/ factor values than the conventional method under linear extinction-ratio characteristics for large-signal modulation. InGaAs/InAlAs MQW modulators are consequently shown to have an /spl alpha/ factor of less than 1.0 under actual driving voltages.<>
