Abstract
A system is provided, the system including at least one integrated optical circuit (IOC) formed from at least one material, and a support-structure configured to support the at least one IOC to couple light between other components. A performance of the at least one IOC is improved by treatment with at least one selected gas.
Claims20
A system comprising:
- at least one integrated optical circuit (IOC) formed from a lithium-niobate-based material, wherein a bandgap of the at least one IOC is increased by exposure to at least one selected fill gas as compared to an IOC operated in a vacuum;
- and
- a support-structure configured to support the at least one IOC to couple light between other components;
- and
- a sealed enclosure enclosing the at least one IOC and the at least one selected fill gas;
- wherein the at least one selected fill gas includes one of:
- nitrogen oxide (NO);
- nitrogen dioxide (NO2);
- sulfur dioxide (SO2);
- nitrous oxide (N2O);
- ammonia (NH3);
- or
- trimethylphosphine (PMe3).

A gyroscope system comprising:
- at least one phase modulator formed from a lithium-niobate-based material, wherein a bandgap of the at least one phase modulator is increased by exposure to at least one selected gas as compared to a phase modulator operated in a vacuum;
- and
- a sealed enclosure in which the at least one phase modulator is enclosed, wherein at least one of the at least one selected gas is enclosed in the enclosure with the at least one phase modulator, wherein the at least one selected gas enclosed in the enclosure with the at least one phase modulator includes one of:
- nitrogen oxide (NO);
- nitrogen dioxide (NO2);
- sulfur dioxide (SO2);
- nitrous oxide (N2O);
- ammonia (NH3);
- or
- trimethylphosphine (PMe3).
