OPTICAL DEVICE WITH PHOTON FLIPPING

摘要

An optical device with photon flipping for converting an incident light flux into a practically monochromatic light beam, the device including a cladding area including a photon crystal microstructure, the photon crystal microstructure having an allowed spectral band and a spectral band gap; a flipping area including a flipping fluorescent dye which has a spectral band for absorbing fluorescence, which covers at least part of the allowed spectral band, and a spectral band for emitting fluorescence, which covers at least part of the spectral band gap of the photon crystal microstructure; a central area arranged to enable propagation of a monochromatic light beam having a wavelength in the spectral band gap, the central area being surrounded by the photon crystal microstructure; the core area having a thickness which is less than or equal to five times the wavelength of the maximum fluorescence emission of the flipping fluorescent dye.
