Abstract:
1. A method of synthesizing an optical signal, the method comprising steps of: generating a multi-bit digital representation of a desired optical E-field, the multi-bit digital representation having a resolution of N1-bits, where N1 is an integer greater than 2; synthesizing at least two analog drive signals based on the multi-bit digital representation, each analog drive signal having a resolution of M-bits, where M is an integer greater than 2; driving an electrical-to-optical (E/O) converter using the analog drive signals; detecting an error between an output optical E-field at an output of the E/O converter and the desired complex E-field waveform; and adjusting at least one parameter so as to minimize the detected error; wherein the step of detecting an error between the output optical E-field and the desired optical E-field comprises steps of:
