Solid immersion lens (SIL) microscopy combines the advantages of conventional
microscopy with those of near-field techniques, and is being increasingly adopted across a …

Numerical studies on a graded negative index lens made by a slab of graded photonic

We report on the realization of all-optical planar microlensing for exciton–polariton
condensates in semiconductor microcavities. We utilize spatial light modulators to structure …

We realize a flat lens with graded negative refractive index by a two-dimensional phononic
crystal. The index-grade is achieved by gradual modification of the filling fraction along the …

We investigate an all-optical microscale planar lensing technique based on coherent fluids

We have realized a graded flat lens with negative effective index operating at telecom
wavelength for Silicon Photonics. We report on its design, fabrication, and experimental …

The imaging behaviors for two kinds of polarized waves found by using a two-dimensional
annular photonic crystal flat lens are theoretically investigated. For the TE-polarization …

We systematically investigated the negative refraction effect for both TM and TE polarization
modes in SiO 2-GaAs annular photonic crystals with triangular lattice. It was found that, in …
