  • Patent number: 7957250
    Abstract: A micro optical head is provided, which provides sub-wavelength focusing spot and very long depth of focus. The optical head includes a transparent substrate, an opaque film, and at least one sub-wavelength annular channel. After coherent light transmits the transparent substrate supporting the optical head and passes through the appropriately designed sub-wavelength annular channel, the transmitted light can overcome the diffraction limit, and the transmission energy is improved efficiently. The transmitted light converges after a certain distance behind the optical head and forms a sub-wavelength-scale beam that maintains a very long distance without divergence.

  • Publication number: 20110036818
    Abstract: An optical etching device for laser machining is provided and includes a laser light source and an optical head. The laser light source emits an incident beam. The optical head includes a transparent substrate, an opaque film and a sub-wavelength annular channel. The laser energy tolerance of the transparent substrate ranges from 8 J/cm2 to 12 J/cm2. The opaque film has a first surface and a second surface opposite to the first surface. The transparent substrate is adhered to the first surface. The sub-wavelength annular channel is formed in the opaque film and extends from the first surface to the second surface so that the incident beam from the transparent substrate generates a surface plasma wave on the opaque film.
