| Abstract: | A passively athermal photonic system including a photonic circuit having
a substrate and an optical cavity defined on the substrate, and passive
temperature-responsive provisions for inducing strain in the optical
cavity of the photonic circuit to compensate for a thermo-optic effect
resulting from a temperature change in the optical cavity of the photonic
circuit. Also disclosed is a method of passively compensating for a
temperature dependent thermo-optic effect resulting on an optical cavity
of a photonic circuit including the step of passively inducing strain in
the optical cavity as a function of a temperature change of the optical
cavity thereby producing an elasto-optic effect in the optical cavity to
compensate for the thermo-optic effect resulting on an optical cavity due
to the temperature change. |
