SANTA CLARA, Calif., Oct. 31 -- Coherent Inc. said that earnings fell during its fourth fiscal quarter as the company's product mix shifted away from higher value telecom products and currency conversions worked against the company. The company said that it booked pro forma income of $5.7 million, or 20 cents per share, excluding a charge of $5.8 million or 20 cents per share. That's down from income a year earlier of $9.5 million, or 33 cents per share, excluding a gain of $33.6 million. Coherent said it plans to take a charge in the first fiscal quarter of 2002 of $1 million to $1.5 million...Read full articleRelated content from Photonics MediaArticlesPhotonic Crystals Imitate Gravitational Effects on LightA group of researchers has replicated the way that light would behave if it were subject to gravity, supporting a recent scientific theory about pseudogravity.
