Silicon microspheres for integrated photonics - art. no. 647606

Abstract

We have experimentally studied the electrical and optical properties of a silicon microsphere with a radius of 500 microns and a refractive index of 3.48 in the near-infrared. The silicon microsphere shows an MSM Schottky diode behavior. The morphology dependent resonances are spaced by 0.2 nm, which correlates well with the estimated mode spacing. The silicon microsphere heralds the way for a novel family of active microphotonic devices.
