radiation length
The average length in a specific material in which a relativistic charged particle will lose 67 percent of its energy by bremsstrahlung.

HANDBOOK > Photonics Handbook® A unique collection of technical design and applications articles, as well as technology primers presenting the basics of the photonics technology.
Connecting Photonic Devices
Two Routes to Achieve Accuracy
Because photonic components such as multiplexers, carrier and pump lasers and attenuators must fit within a network and survive up to 20 years, how they are connected is a critical issue. Photonic devices that contain lenses, crystals, laser diodes and photodetectors demand exact alignment. The fiber optics that conduct signals in and out of these devices are precisely attached and aligned to the internal optical components. Consequently, placement of these miniature parts requires such a high...
