Dielectric and Semiconductor Micro Spheres and Silica Optical Fibers for Optoelectronic Applications


Ali Serpengüzel

Koç University, Microphotonics Research Laboratory, Physics Department.


Abstract: Silicon is the most widely available semiconducting material on earth. Silicon based microelectronics integrated circuit (IC) technology is continuously developping according to the “Moore’s Law,” making the IC physically bigger and the signal paths longer every year. Silicon based electrophotonic integrated circuits (EPIC) are a possible solution to synchronous clock distribution within an IC. EPIC requires the addition of photonic elements to the electronic circuit elements. Two dimensional (2D) planar light wave circuits (PLCs) are being developped using microdisks/microrings as active or passive photonic circuit elements. A three dimensional (3D) extension of these PLCs can be envisioned as volume light wave circuits (VLCs). The microspheres are the natural extensions of the microdisk/microring and can be integrated in 3D. The microsphere has high quality factor morphology dependent resonances (MDR’s), which can be used in wavelength division multiplexing (WDM) optical communication. In this talk, silicon microspheres will be investigated for their unique electrophotonic applications such as resonant filters, detectors, modulators, and light sources.
