Once in a Blue Moon

Why does the phrase “once in a blue moon” mean “rarely”? Is it because, on unusual occasions, atmospheric conditions conspire to create a moon that appears blue? Or does a “blue moon” occur when there are two full moons in a single month—another uncommon occurrence? more>>

A New Model for the Optoelectronic Indium-based Semiconductor Industry

Foundry-based companies have driven the silicon semiconductor industry to huge success. Could a similar approach work in the struggling indium- based market? more>>


Photo Contest

After Image Photo Contest

The staff of Optics & Photonics News would like to invite you to participate in our first-ever After Image photography contest. As our devoted readers know, the After Image column appears regularly on our back page and consists of a large, full-page image that demonstrates some aspect of the field of optics, or an image that was created using optical equipment. more>>
