Typical methods for optical vector analysis have tradeoffs among resolution, dynamic range, and bandwidth. The authors use an asymmetric optical probe signal generator and receiver to perform attometer resolution measurement over a THz of bandwidth while maintaining high dynamic range, aiming to characterize emerging optical devices.
