Curie’s Symmetry Principle for Selection Rule of Photonic Crystal Defect Modes
Symmetry, which defines invariant properties under a group of transformations, provides a frame of generalization uncovering regularities from given quantitative descriptions. Based on the Curie’s symmetry pri...

Thickness tolerance compensation of SIL first surface near-field recording with replicated lens on SIL
In this paper, we propose a novel optics design for improving the thickness tolerance of a super-hemispherical solid immersion lens (SIL) that is usually used in near-field recording for high data density. To ...

Design of near-field recording optics using truncated hemispherical SIL with cover-layer incident dual recording layers
In this paper, we propose a novel optics design for media inside near-field recording (NFR) using a truncated hemispherical solid immersion lens (HMS). To obtain strong advantage of data protection and high da...
