Paper Abstract

The advent of optical waveguides with a unique geometry, where the central part is of low refractive index as compared to the material on the sides, here-after named as a slot(s) guarded by slabs with unique properties of light confinement opened new opportunities for lab-on-chip circuits. Apart from passive dispersion compensator circuits (proposed by us for the first time), active optical circuits have also been designed (by other researchers). In this research we are in a quest to harvest the benefits of Silicon-on-Insulator (SOI) slot optical waveguides in the area of photo-voltaic solar power generation; earlier we have proposed simple and easy to implement periodic/ basic multiple air cladded slot structures. In this research work, we have implemented buried SOI slot optical waveguides; the solar spectrum incarceration with our earlier research work is also being compared. With the advancement in nano-technologies, it is never a problem to implement nanometers wide optical waveguides on the window glass. Where conventional photovoltaic solar cells will be embedded either on all corners of a micro-meter wide region or maybe only on one side. The research will open new avenues for researchers in the field of photovoltaic power generation.
