Optically controlled loss in an optical fiber

Optics Letters, 2009
The use of upconversion to attenuate/modulate optical signals is proposed, and experimental results are presented. In this light controlling light approach, a 711.2 nm, 700 mW beam propagating in a Tm(3+)-doped fluorozirconate optical fiber was attenuated down to 150 mW by copropagating a 1117 nm beam.

Optic Nerves, Optic Chiasm, and Optic Tracts

1988
The vertebrate optic nerves, optic chiasm, and optic tracts contain axons of retinal ganglion cells. These axons connect the retina, where light absorption produces patterned neuronal firing, to the brain, where these firing patterns can undergo further processing.

Optical engineering and the Optical Society of America

Applied Optics, 1982
The role of the Optical Society of America in the changing field of optical engineering is discussed by the vice-chairman of the Technical Council of OSA in an introduction to a group of papers that constitutes a representative sampling of optical engineering in the early Eighties.

Optical Bistability and the Digital Optical Computer

Topical Meeting on Optical Bistability (OB3), 1985
Electrons are well suited for switching operations as they occur in a logic processor. But electrons are not so easy to guide from one point to another point. On that score, photons are more suitable. Recently, photons became amendable also for logic processing. Hence, the stage is set for the development of an all-optical digital computer.
