Slot waveguides are very promising for optical sensing applications because of their peculiar spatial mode profile. In this paper we have carried out a detailed analysis of mode confinement properties in slot waveguides realized in very low refractive index materials. We show that the sensitivity of a slot waveguide is not directly related to the refractive index contrast of high and ... https://www.bekindtopets.com/bargain-Mr-Robot-Toy-Vinyl-Bumper-Sticker-mega-super/
