Ion Exchange Method

In recent years, a series of gradient index (GRIN) materials including Optical glass and polymer have been Research and developed in our laboratory. The Micro-lenses and arrays with the special optical materials also have been fabricated mainly by using Ion-exchange method through refractive index profile, which are applied to micro-optic devices and other applications—— especially in the coupled and connected devices for fiber communications and medical endoscope or they are used primarily for document scanning equipments.

Plasmon Polaritons

This study theoretically investigated light reflection and transmission in a system composed of a thin metal layer (Ag) adjacent to a rugate filter (RF) having a harmonic refractive index profile. Narrow dips in reflectance and peaks in transmittance in the RF band gap were obtained due to the excitation of a Tamm plasmon polariton (TPP) at the Ag–RF interface. It is shown that the spectral position and magnitude of the TPP dips/peaks in the RF band gap depend on the harmonic profile parameters of the RF refractive index, the metal layer thickness, and the external medium refractive index. The obtained dependences for reflectance and transmittance allow selecting parameters of the system which can be optimized for various applications.
