Traditionally, semiconductor devices including optoelectronic devices like lasers and light emitting diodes are fabricated on hard inflexible substrates; these have been used for a large number of applications including computers, portable electronics and biomedical applications. However, flexible electronics is an increasingly important area as it can be used for large scale displays which can be rolled up into small rolls, portable power sources using photovoltaics, conformed on skin for sensing, large scale organic light emitting diode (OLED) lighting and many other applications. The biggest advantage of the flexible electronics devices is their application in areas where traditional rigid electronics cannot be used like disposable sensors, displays, and cheap solar cells.***Optical materials play an extremely important role in our day-to-day life with their utilization in items of everyday use like lighting, displays, etc. Flexible light sources have several advantages including low power consumption; they can be applied in general lighting and portable electronics along with biophotonics and biomedical applications. The biomedical applications include therapeutic applications like nerve stimulation, photodynamic therapy and LED based biosensors.***This research program will focus on the development of novel flexible optoelectronics solutions for lighting, photovoltaic and sensing applications. It will combine using organic and inorganic materials to fabricate flexible electronic and optoelectronics components. The approach that will be pursued to develop flexible optoelectronic devices will be to use low temperature growth techniques like pulsed laser deposition to grow optical materials directly onto flexible substrates. These substrates are biocompatible, which will enable biosensing in addition to other sensing applications. The research program will involve developments in optics, materials and devices to develop flexible optoelectronic devices, biosensors and biophotonic applications.***The major advances in the field of flexible electronics that will be accomplished by this research program are the integration of flexible electronics with optical components, the development of tunable light sources that will provide multifunctionality to the devices, and the focus on developing viable, efficient and reliable hybrid devices integrating inorganic and organic components.**
