ABINGDON, U.K., March 13, 2003 (PRIMEZONE) -- Bookham Technology plc (LSE:BHM) (Nasdaq:BKHM) will present a paper at the Optical Fiber Communication Conference and Exposition in March 2003 that describes a novel 40Gbit/s electro-absorption modulator (EAM) module with unequalled performance. Based on the Franz-Keldysh effect (FKE), the EAM device has the lowest unamplified insertion loss ever reported for an EAM, the lowest polarisation-dependent loss (PDL) over a wide range of wavelengths, and the highest bandwidth for a lumped-element FKE-EAM. All these performance parameters are achieved simultaneously, with a manufacturable design, while maintaining the practical requirement of over 10dB extinction with a voltage swing of under 2.5V.
