Broadlight secures another GPON patent

June 4, 2008
JUNE 4, 2008 -- BroadLight says it has secured U.S. patent number 7,356,058, which enables the implementation of a burst mode laser driver for PON applications in a standard CMOS silicon process.

JUNE 4, 2008 -- BroadLight (search for BroadLight), supplier of GPON semiconductors and software, has received a U.S. patent, number 7,356,058, which enables the implementation of a burst mode laser driver for PON applications in a standard CMOS silicon process. BroadLight has already secured Intellectual Property Rights throughout the GPON system, and the addition of this patent further strengthens its competitive position, say company representatives.

"BroadLight's optical transceiver expertise in PON enabled us to design the burst mode laser driver in a standard CMOS process and to demonstrate its performance," reports Igor Elkanovich, vice president of VLSI for BroadLight. "This allows us to plan a breakthrough and unique level of integration between the PON SoC and its optical front end."

The patent outlines an adaptive laser diode driver capable of driving various laser types as well as accommodates the variations in lasers for ensuring optimal optical performance and calibration during manufacturing and operation over lifetime and temperature variations. The driver adaptively conditions output modulation and bias signals for optimal laser operation. This adaptive laser diode driver can be integrated in optical line terminal (OLT) or optical network unit (ONU) devices.
