Johan Holm Honored by Danish Optical Society for PING Gratings

Photonics.com
Dec 2006
JohanHolm.jpgJohan Holm has received the DOPS prize from the Danish Optical Society for developing Ibsen Photonic's polarization-independent fused-silica telecom gratings. Ibsen Photonics is a Farum, Denmark-based maker of phase masks and transmission gratings for the telecom, sensing and laser markets. The DOPS prize is an annual award given to an individual whose contribution to the Danish optics field has been of "unique quality and importance." The award was presented to Holm for his work since 2000 in connection with the development and commercialization of Ibsen's PING gratings, used primarily in telecom ROADM/WSS modules. The gratings offer high efficiency and low PDL over a very broad bandwidth with unique thermal and environmental stability due to their fused-silica nature. Ibsen said it has incorporated the gratings into its I-MON FBG sensor system interrogation monitors for compact, high-resolution narrow-band spectrometers.


GLOSSARY
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
polarization
With respect to light radiation, the restriction of the vibrations of the magnetic or electric field vector to a single plane. In a beam of electromagnetic radiation, the polarization direction is the direction of the electric field vector (with no distinction between positive and negative as the field oscillates back and forth). The polarization vector is always in the plane at right angles to the beam direction. Near some given stationary point in space the polarization direction in the beam...
sensor
1. A generic term for detector. 2. A complete optical/mechanical/electronic system that contains some form of radiation detector.
