Download or read book Nanoparticle-coated Optical Microresonators for Whispering-gallery Lasing and Other Applications written by Siyka Ivanova Shopova and published by . This book was released on 2007 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Findings and conclusions. Lasing in HgTe was demonstrated for the first time and record low thresholds were measured in these devices. Interesting effect on enhancement of evanescent coupling was observed with microsphere resonators with gold nanorods grown on their surfaces. We develop a new procedure that uses semiconductor nanoparticles as seeds for growth of gold nanorods.
