Method and system for multiple resonance interferometer

摘要

A multiple resonance interferometer structure includes an input port and a first arm coupled to the input port and including a first resonant structure. The multiple resonance interferometer also includes a second arm coupled to the input port and including a second resonant structure and an output port coupled to the first arm and the second arm.

1. A method of modulating a signal, the method comprising:
receiving an optical signal at an input port; splitting the optical signal into a first arm signal and a second arm signal; adjusting a DC bias phase of the first arm signal or the second arm signal using a first phase control element; introducing a first predetermined phase delay in the first arm signal using a first resonance structure, wherein:
the first predetermined phase delay is equal to +/−φ;the first predetermined phase delay is introduced using a second phase control element; andthe first resonance structure is a ring structure; introducing a second predetermined phase delay in the second arm signal using a second resonance structure, wherein:
the second predetermined phase delay is equal to −/+φ;the second predetermined phase delay is introduced using a third phase control element; andthe second resonant structure is a ring structure; combining the phase delayed first arm signal and the phase delayed second arm signal to provide a modulated signal; and transmitting the modulated signal at an output port.
