  • Power polarization beam combiner and its applications in fiber communication
    Patent number: 7295373
    Abstract: This specification discloses a power polarization beam combiner and its applications in fiber communications. The power polarization beam combiner uses the photonic band gap formed in a photonic crystal to produce a left-hand material with a negative refractive index and high dispersion rate. Using such properties of the photonic crystal, several beams with different wavelengths and polarizations are combined and output to a common port.

  • Microcavity semiconductor laser
    Patent number: 5825799
    Abstract: Laser comprising a first lasing microdisk, microcylinder or microannulus defining a microcavity having a circular cross-sectional periphery and a second waveguiding micromember spaced from the first lasing micromember in a different plane and optically coupled by resonant photon tunneling. The second waveguiding micromember includes a light output coupling for providing light output from the laser without adversely affecting the Q value and low lasing threshold of the microcavity.
