Abstract

In this talk, I will present the development of advanced laser resonator

systems, their applications to laser-micromachined active and passive

photonic device integrations, and nanophotonic device fabricationsbased on

biomimetic systems. I will focus on novel high intensity ultrafast lasers,

hybrid semiconductor fiber lasers, and one-dimensional photonic crystal

lasers made with nanostructured block-copolymers. In addition, ultrahigh

resolution imaging in vivo using ultrafast lasers will be presented as an

example for photo-medicine. In order to demonstrate these lasers and

passive devices, the theoretical models are introduced along with

confirming experimental results. Moreover, the goal of scaling down

current photonic systems can be achieved by the integration of organic and

inorganic nanostructures. Specifically, the incorporation of genetically-

engineered biological species can provide a viable scaffold for the

synthesis of nanostructures that are made of metals, semiconductors, and

dielectrics. Finally, I will discuss potential applications of these

biomimetic structures to quantum-confined nano-photonic devices such as

lasers, photovoltaic cells, and bio/chemical senso.
