Research Abstract

By the Vibrating Orifice Technique (A cylindrical liquid jet passing through the orifice of 10-20μm in diameter breaks up into equal-sized droplets by mechanical vibration of high frequency), equal-sized hybrid microsphers of several micrometer in diameter were successflly fabricated. These microsphers meet the optical cavity requirements : mono-dispersed and showed highly transparent and good sphricity.
The following achievements were accomplished.
(A) Lasing was performed in dye-doped microspheres prepared from phenyltriethoxy silane as a starting material. Most stable conditions of lasing were clarified : dye content and excitation laser power. Dyes were Rhodamine 6G, DCM and Pyridine 1. After 240,000 pulse shot (about 7 hour-irradiation), the initial lasing power intensity decreased to 50%.
(B) Encapsulation of light need high relative refractive index >1.5 between microsphere here and the surrounding media. Thus the microsphere itself is required index >2.0. Hybrid microspheres of refractive index >2.0 was developed
(C) Optical waveguide of hybrid materials were made by the photolithography technique and the excitation of microsphere was performed using the waveguide.
