Analytical study of optical component for optogenetic application

Optogenetics is a combined technology of optics and genetics to achieve gain or loss functions of well defined events within specific cells of a living tissue. That is why in optogenetics there is need to choose specific optical components which cause no harm to cells or tissues or any kind alteration of cells. In optogenetics, stimulation of neurons strictly depends on optical power density received in the brain. In this paper, via simulation, we have shown dependency of optical power density for stimulation of neurons using three different wavelengths and for various parameters on which irradiance depends like, core radius, input light power and numerical aperture of the fiber.
