报告人简介:

    Ravinder K. Jain, APS fellow, IEEE fellow, OSA fellow and SPIE fellow, received the M.S. in Electrical Engineering & Computer Sciences in 1972 and the Ph.D in Electrical Engineering & Computer Sciences in 1975 from the University of California, Berkeley. He is an associate editor in Optics Express.

    He is a Professor in ECE and Physics at University of New Mexico. His research focuses on lasers, optics, photonics and nonlinear optics.

 

报告摘要:

    Glasses are used for numerous photonic structures including optical fibers, on-chip waveguides and microresonators. Depending on the specific geometry, many of these structures lead to important linear and nonlinear optical phenomena, and undoped glasses lend themselves quite naturally to a broad range of sensors, especially via evanescent-wave interactions, both in linear waveguides and in closed resonator structures.

    The optical properties of free ions doped in glasses depend strongly on local field environments – and more critically on – the distribution of phonon energies in these glasses. As such, the luminescence properties of ions in glasses depend very strongly on honon energies and multi-phonon relaxation, which can play a severe role for mid-infrared transitions.

    I will discuss some of these effects and the use of appropriate ions in glasses for demonstration of efficient lasing in the mid-infrared. The role of using semiconductor nanoparticle “cages” embedded in these glasses for next generation laser gain media will be explored.

    Last, but not the least, I will discuss the use of plasmonic nanostructures with semiconductor quantum dots for unique nonlinear optical and sensing phenomena.
