Project aims to fabricate novel silicon based optical switches in the form of cantilevered mirrors integrated to interface with silica optical waveguides integrated collimation lens. Significantly, it paves the way for low cost integration of optical switches with array waveguides for an all-optical dynamically reconfigurable dense wavelength division multiplexing network used in modern broadband telecommunication systems. International market demand for such devises is enormous.

New Approaches for Wireless Implantable Biomedical Devices. Wireless biomedical implants of the future will interface with biological systems to perform physiological tasks such as vision restoration, reanimation of paralyzed limbs, and chemical sensing. The potential benefit to society will come not only from alleviating human suffering and improving quality of life, but also by reducing the health care costs now directed to assist people with disabilities such as blindness, stroke and spinal-c ....New Approaches for Wireless Implantable Biomedical Devices. Wireless biomedical implants of the future will interface with biological systems to perform physiological tasks such as vision restoration, reanimation of paralyzed limbs, and chemical sensing. The potential benefit to society will come not only from alleviating human suffering and improving quality of life, but also by reducing the health care costs now directed to assist people with disabilities such as blindness, stroke and spinal-cord injury survivors. Using similar technologies, cochlear implants have already restored functional hearing to over 100,000 deaf patients around the world. The outcomes of the project can also be applied to a variety of other applications such environmental monitoring, security and identification systems. Read moreRead less

We will develop electronic building blocks to investigate biological signal processing. In particular, we will investigate the auditory pathway and develop the most accurate electronic model of the biological cochlea and auditory nerve. These will be followed by electronic circuits that model the processing of sensory signals in the brain. Processing signals with neural spikes offers distinct advantages over current analogue and digital signal processing techniques in terms of noise, energy consumption and extraction of temporal information. We will implement the first spike-based models of pitch and timbre perception, and a neural model of speech recognition in noisy environments.Read moreRead less
