Digital-to-analog converter system and method of operation

Abstract

A digital-to-analog converter (DAC) system preferably includes one or more optical modulators and can optionally include one or more electronic DAC arrays. A method for digital-to analog conversion preferably includes receiving digital inputs and providing analog optical outputs. The method for digital-to analog conversion is preferably performed using the DAC system.

We claim: 
     
         1 . A method for digital-to-analog conversion, comprising:
 receiving a digital signal representative of a value;   based on the digital signal, generating a plurality of control signals, wherein the plurality of control signals cooperatively define a digital representation representative of the value;   providing a first control signal of the plurality as a first electrical input to a first segment of a microresonator;   providing a second control signal of the plurality as a second electrical input to a second segment of the microresonator; and   while providing the first and second control signals, generating an analog optical signal representative of the value, comprising filtering an optical input at the microresonator based on the first and second electrical inputs.
