We propose a core selective switch (CSS) with VOA function utilizing liquid crystal polarization grating and MEMS technology. The prototype of 19-core 1×8 CSS showed an attenuation of 19.5 dB with more than 35 dB optical crosstalk.

We prototyped a 15-core 1×8 core selective switch (CSS). The high core count CSS is achieved by bundling three 5-core fibers (5-CFs) and collimating/demultiplexing beams from the input bundled three 5-CFs using a single microlens.

It is possible to construct a hollow optical waveguide trapping light in air or a vacuum by means of reflectors with high reflectivity. In this paper, a variable function is proposed to vary the propagation constant and the velocity of the light prop

We present the fabrication and characterization of a novel distributed Bragg reflector consisting of a grating loaded slab hollow waveguide. In this structure, we are able to obtain a high reflectivity even by using thin and short surface gratings be
