Abstract: 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.

Abstract: Provided are a self-selecting memory device having polarity dependent threshold voltage shift characteristics and/or a memory apparatus including the self-selecting memory device. The memory device includes a first electrode, a second electrode apart from and facing the first electrode, and a memory layer between the first electrode and the second electrode. The memory layer has Ovonic threshold switching characteristics and is configured to have a threshold voltage of the memory layer be changed as a density of active traps in the memory layer is changed, the threshold voltage changing according to the polarity and the intensity of a bias voltage applied to the memory layer. Furthermore, an element composition distribution is configured to be maintained constant in the memory layer in response to the threshold voltage of the memory layer changing.

Abstract: An optical filter may include a first reflector and a second reflector. The first reflector may include a plurality of first gratings having a first sub-wavelength dimension and being arranged to recur at a first interval in a first direction. The second reflector may be spaced apart from the first reflector and include a plurality of second gratings having a second sub-wavelength dimension and arranged to recur at a second interval in a direction parallel to the first direction. The first reflector and the second reflector may include different materials or different geometric structures from each other. Accordingly, it is easy to adjust the transmission wavelength characteristics of the optical filter.
