Various embodiments may provide an optical structure. The optical structure may include a substrate. The optical structure may also include a core layer configured to carry optical light. The core layer may include germanium. The optical structure may further include an intermediate layer separating the substrate and the core layer so that the substrate is isolated from the core layer. The intermediate layer may include one or more materials selected from a group consisting of III-V materials, dielectric materials, and chalcogenide materials. A width of the core layer may be smaller than a width of the intermediate layer. A refractive index of the core layer may be more than 4. A refractive index of the intermediate layer may be smaller than 3.6.
