Modern nanotechnology allows one to scale down various important devices (sensors,
chips, fibers, etc.) and thus opens up new horizons for their applications. The efficiency of …

Recently, strongly modulated photonic crystals, fabricated by the state-of-the-art
semiconductor nanofabrication process, have realized various novel optical properties. This …

For decades, silicon has been the material of choice for mass fabrication of electronics. This
is in contrast to photonics, where passive optical components in silicon have only recently …

We demonstrate a concept for tailoring the group velocity and dispersion properties for light
propagating in a planar photonic crystal waveguide. By perturbing the holes adjacent to the …

We demonstrate experimentally that the spectral sensitivity of an interferometer can be
greatly enhanced by introducing a slow-light medium into it. The experimental results agree …

Water quality evaluation of Kanhan river and its tributaries viz. Pench and Nag rivers was
carried out in order to assess the qualitative changes and possibility of point and non-point …

We study the resonant transmission of light in a coupled-resonator optical waveguide
interacting with two nearly identical side cavities. We reveal and describe a novel effect of …

Photonic crystal tapers have been designed for coupling of light from ridge waveguides into
low group velocity photonic crystal channel guides. The coupling efficiency is increased from …

The authors report a direct, single-shot measurement of the group index profile of photonic
crystal waveguides, combining spectral interferometry with Fourier transform analysis. This …

While ideal photonic crystals would support modes with a vanishing group velocity, state-of-
the-art structures have still only provided a slow down by roughly two orders of magnitude …
