    Abstract: Embodiments of the invention describe a multi-segment optical waveguide that enables an optical modulator to be low-power and athermal by decreasing the device length needed for a given waveguide length. Embodiments of the invention describe an optical waveguide that is folded onto itself, and thus includes at least two sections. Thus, embodiments of the invention may decrease the device size of a modulator by at least around a factor of two if the device is folded twofold (device size may be further reduced if the modulator is folded threefold, four-fold, five-fold, etc.).Embodiments of the invention further enable the electrode length required to create the desired electro-optic effect for the multi-segment optical waveguide to be reduced. In embodiments of the invention, certain electrodes may be “shared” amongst the different segments of the waveguide, thereby reducing the power requirement and capacitance of a device having a waveguide of a given length.
