Abstract:
An investigation of the losses exhibited by antiresonant ref lecting optical waveguides (ARROW's) formed from solution-deposited solgel films is reported. Solgel layers formed from methyltrimethoxysilane (MTMS) and titanium (iv) propoxide were used to fabricate a simple ARROW structure. Using a combination of MTMS and titanium (iv) propoxide produced good optical quality layers with thicknesses ranging from 1 to 20 microm. Losses as low as 2 dB/cm were measured experimentally for these ARROW devices.
