The present invention relates to a shape-variable electronic device and an operation method of the same and, more specifically, the shape-variable electronic device includes: a substrate having a cell region; a light source unit on the cell region; and a flexible layer vertically spaced apart from the light source unit. The flexible layer includes an actuator part that changes a shape of the flexible layer, and the actuator part includes: a photo-thermal response part that receives light emitted from the light source unit and generates thermal energy; a deformation part which receives the thermal energy from the photo-thermal response part and of which mechanical stiffness is reduced; and a top electrode and a bottom electrode on both surfaces of the deformation part, respectively.

Nonreciprocal optical transmission devices and optical apparatuses including the nonreciprocal optical transmission devices are provided. A nonreciprocal optical transmission device includes an optical input portion, an optical output portion, and an intermediate connecting portion interposed between the optical input portion and the optical output portion, and comprising optical waveguides. A complex refractive index of any one or any combination of the optical waveguides changes between the optical input portion and the optical output portion, and a transmission direction of light through the nonreciprocal optical transmission device is controlled by a change in the complex refractive index.
