Abstract
Techniques that facilitate control of dual phase tuners are provided. In one example, a system includes a first phase tuner and a second phase tuner. The first phase tuner is driven to a first phase bias that is different than a desired phase bias for an interferometer. The second phase tuner is driven to a second phase bias. A combination of the first phase bias and the second phase bias corresponds to the desired phase bias.
Claims11
A system, comprising:
- a first phase tuner that is driven to a first phase bias that is different than a defined phase bias for an interferometer;
- and
- a second phase tuner that is driven to a second phase bias, wherein a combination of the first phase bias and the second phase bias corresponds to the defined phase bias, wherein the first phase tuner is driven to a third phase bias equal to zero in response to a determination that a phase shift value associated with the first phase tuner is above 180 degrees, and wherein the first phase tuner is driven to the third phase bias after the first phase tuner is driven to the first phase bias.
