Abstract
Optical switches and logic devices comprising microstructure-doped nanocavity lasers are described. These switches and logic devices have gain and thus can be cascaded and integrated in a network or system such as for example on a chip. Exemplary switching elements switch the intensity, wavelength, or direction of the output. Exemplary logic devices include AND, OR, NAND, NOR, NOT, and XOR gates as well as flip-flops. Microfluidic sorting and delivery as well as optical tweezing and trapping may be employ to select and position a light emitter in an nanooptical cavity to form the nanolaser.
Claims27
A method of fabricating a nanocavity laser, said method comprising:
- pumping a laser cavity that supports an optical mode having an optical field concentrated in a region of said laser cavity;
- and
- optically trapping a light emitter in said region of said laser cavity, the light emitter configured to provide optical gain for said laser cavity.
A method of fabricating a nanocavity laser, said method comprising:
- flowing a liquid comprising a plurality of light emitters therein through a region;
- illuminating said plurality of light emitters in said region with light;
- detecting radiation emitted from said light emitters flowed through said region;
- selecting at least one of said light emitters based on said radiation detected;
- and
- delivering said at least one light emitter to a laser cavity, said light emitter configured to provide optical gain for said laser cavity.
A method of fabricating a nanocavity laser, said method comprising:
- providing a microstructure-doped laser cavity comprising microstructures formed in a matrix having an opening therein, said opening being less than about 500 nanometers wide;
- and
- inserting a light emitter in said opening by flowing a fluid containing said light emitter in the proximity of said opening, said light emitter configured to provide optical gain for said laser cavity.
A method of fabricating a nanocavity laser, said method comprising:
- providing a laser cavity that supports an optical mode having an optical field concentrated in a region of said laser cavity when said laser cavity is pumped;
