Blue Sky Research Announces Laser Diode Sources for Free Space Optical Communications

Low and High Power Laser Diode Sources With Ideal, Round Beams Extend

The Range and Reliability of Fiberless Laser Communication



Apr 02, 2001, 01:00 ET from Blue Sky Research

    SAN JOSE, Calif., April 2 /PRNewswire/ -- Blue Sky Research, a privately
 held developer and manufacturer of high-performance, cost-effective optical
 network components, today officially announced the availability of its
 Free-Space Telecom Laser Sources for "fiberless" optical communications.
 Free-Space Telecom Laser Sources use the Company's proprietary microlens
 technology to produce more reliable line-of-sight, free-space optical data
 transmission, especially through atmospheric interferences.
     "Simply put, our proprietary microlens technology produces an ideal
 quality laser beam that transmits four times the signal through fog, the
 toughest challenge in Free-space communication," said Dan Hu, president and
 CEO of Blue Sky Research.
     Free-space optical communications is only practical if it can be done
 reliably through atmospheric interferences such as fog. Blue Sky Research's
 laser sources enable delivery of collimated uniform laser beam power over
 greater distances and with greater penetrating power to overcome weather
 effects. Blue Sky Research's laser sources use the Company's proprietary
 microlens technology in combination with a variety of laser diodes. The
 microlens concentrates the diodes' power into a circular, aberration-free,
 ideal beam, which translates into more transmitted power arriving at the
 detector.  A recent test showed that four times the laser power arrived at the
 detector through fog using a Blue Sky Research laser source compared to other
 laser transmitters.  Also, the microlens converts essentially 100% of the
 diode's beam power into a useful communications signal.  This added efficiency
 allows either running the diodes at reduced operating conditions, which
 extends the diodes' lifetime and reliability, or using lower cost, lower-power
 diodes.
     Free-Space laser sources are available now, as TO-can laser diodes,
 modules or fiber pigtailed packages. They are offered with wavelengths from
 780 to 1550nm and power ratings from 5mW to 150mW. Contact Blue Sky Research
 for application-specific cost and delivery information.
 
     About Blue Sky Research
     Blue Sky Research, headquartered in San Jose, California, is an innovative
 optical network components company that develops and manufactures key products
 essential for the deployment of optical communications networks. The Company
 has a series of products including EDFA Pump modules, Optical Cross Connect
 Switches, Programmable ITU Lasers, and Free-Space Laser Sources scheduled for
 release in 2001/2002. The company's patented technologies form a solid base
 for significant product price/performance advantages in telecommunications and
 other electro-optics applications. Since entering commerce in 1995, Blue Sky
 Research has been building upon its proprietary technologies and volume
 manufacturing expertise. The company has experienced continuous expansion and,
