Abstract
An optical converter is so arranged that light to be measured and probe light are made to interact with each other on a nonlinear element and that mixed light produced by the interaction is detected, which is characterized in that an energy amount of interacting signal light is kept as high as possible without spatial expansion of signal light, which could lower the SN ratio. For this, the time-space conversion function is achieved by a method for producing the probe light. Namely, the optical converter comprises (a) a nonlinear element for making two types of light interact with each other to cause the nonlinear optical effect, (b) a device for guiding light to be measured to the nonlinear element, and (c) a device for producing probe light crossing the light to be measured on the nonlinear element and changing a traveling direction of probe light with change of crossing time. A light waveform measuring apparatus or an optical serial-parallel converter may be attained by adding to the optical converter (d) a device for detecting mixed light produced by the interaction between the signal light and the probe light on the nonlinear element.
