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.
Claims31
Laser comprising a first micromember having a lasing microcavity with a substantially circular cross-sectional periphery and a second waveguiding micromember spaced from said first micromember in a different plane and optically coupled to said first micromember, said second waveguiding micromember including a light output coupling for providing light output from said laser.
Laser comprising a substrate, a first microdisk spaced above said substrate and having lasing microcavity with a circular cross-sectional periphery and a second waveguiding microdisk spaced above said first microdisk and optically coupled thereto, said second waveguiding microdisk having a light output coupling for providing light output from said laser.
Laser comprising a substrate, a first microcylinder having a lasing microcavity with a circular cross-sectional periphery and a second waveguiding microcylinder spaced between said substrate and said first microcylinder and optically coupled thereto, said second waveguiding microcylinder having a light output coupling for providing light output from said laser.
Laser comprising a first micromember having a lasing microcavity and a second waveguiding micromember spaced from said first micromember in a different plane and optically coupled to said first micromember, said second waveguiding micromember including a light output coupling for providing light output from said laser.
