Abstract: The EM polarizing structure contains a two dimensional planar variation structure, having medium nodes regularly distributed as a two dimensional planar photonic unit lattice cell array on a plane. Each of the photonic unit lattice cells has an operation axis and is identical at each lattice point, which passes a diagonal of photonic unit lattice cell. The medium nodes within each planar photonic unit lattice cell are distributed asymmetrical with respect to the operation axis direction and identical at each lattice point. The EM polarizing structure is used to modulate an input EM wave around an operation frequency of the photonic band associated with the EM wave polarizing structure. Thus a corresponding output EM wave becomes polarized. Moreover, the EM wave polarizing structure can be integrated with an EM wave emitting source. Thus an output EM wave from the device is polarized.

Abstract: A light emitting apparatus at least includes a light emitting device, a connecting wire structure, and a space-occupation body. The light emitting device is disposed in the space-occupation body, electrically coupled with the connecting wire structure, and emits a first-frequency-range light under a suitable driving voltage. A light emitting surface of the light emitting device structure is covered by a first anti-reflection layer with respect to the first-frequency-range light. A packaging material is filled into the space-occupation body. The packaging material at least includes a luminescent material. The luminescent material is excited by the first-frequency-range light, so as to generate at least a second-frequency-range light.

The said EM polarizing structure is used to modulate an input EM wave around an operation frequency of the photonic band associated with said EM wave polarizing structure. Thus a corresponding output EM wave becomes polarized. Moreover, said electromagnetic (EM) wave polarizing structure can be integrated with an EM wave emitting source. Thus an output EM) wave from said device is polarized.
