Photonic force microscopy (PFM) is an optical-tweezers-based microscopy technique. A small dielectric particle (20 nm to several micrometres) is held by a strongly focused laser beam. The forward scattered light, i.e. the light whose orientation is slightly changed while passing through the particle, and unscattered light are collected by a lens and projected onto a Quadrant Photo-Diode (QPD), i.e. a Position sensitive device (PSD). These two components interfere in the … Web1 hour ago · Highly reconfigurable silicon integrated microwave photonic filter towards next-generation wireless communication.
