Hybrid Photonic Devices Based on Colloidal Quantum Dot Composites

Vinod M. Menon, Queens College of CUNY, Flushing, NY

In this talk we will discuss our work on organic-inorganic hybrid photonic devices that allow us to exploit the properties of the two different material systems. Specifically we will report our recent work on photonic emitters and circuits that utilize colloidal quantum dot composites comprising of the inorganic quantum dots in an organic host matrix as the active medium. Some of the prototype devices that will be discussed include flexible microcavity laser, active micro-resonators integrated with passive waveguides, and quasi-periodic photonic structures. All of the above devices are fabricated using simple spin coating or soft-lithography. In addition to their specific functionalities, these novel device demonstrations and their development present a low cost alternative to the traditional photonic device fabrication techniques.
