Integrated optics |
September 27, 1994 |
| Lasing threshold for a whispering mode laser is reduced by appropriate placement of a reflector. A reflector parallel to, and within a wavelength distance of, the disk decreases radiation loss due to imperfect internal reflection. Enhancement is calculable on the basis of destructive |

Whispering mode micro-resonator |
August 30, 1994 |
| Device for electromagnetic emission depends on total internal reflection-on whispering gallery mode cavitation about the periphery of a disk-shaped element of sub-wavelength thickness. As a laser, operating above threshold, the design is alternative to that of the Surface Emitting Laser |

Distributed Bragg reflectors and devices incorporating same |
October 27, 1992 |
| Distributed Bragg Reflectors of high efficacy based on alternating layers of large difference in refractive index are fabricated by epitaxial growth followed by etchant removal and back-filling to produce a structure in which alternation is between layers of retained epitaxially grown ma |

Optical integrated circuit designed to operate by use of photons |
September 15, 1992 |
| Optical integrated circuitry, performing various of the functions associated with electronic integrated circuitry, is disclosed. Fabrication, importantly to achieve high circuit chip density--typically in the range of 10.sup.6 as including both devices and interconnecting guides--is |
