Radiometric Measurement
Radiometry is the measurement of energy or power in electromagnetic radiation fields or light. The average output power is the most common radiometric measurement since many light sources, ...
Technical Notes
Photoreceiver Characteristics
The characteristics of such high-speed photoreceivers as well as their associated applications are the subjects of this technical note.
Technical Notes
Types of Photoreceivers
The main types of photoreceivers are those that can detect optical signals with fast temporal responses or those containing high frequency components.
Technical Notes
Laser Beam Profile Measurement
Given the different types of laser beam spatial distributions and their evolution as they propagate in free space and through optical elements, measurement of the beam profile is critical ...
Technical Notes
Laser Pulse Characterization
Accurate temporal characterization of pulsed sources is as critical as accurately estimating the pulse energy and spatial and spectral profiles.
Technical Notes
Optical Mirror Physics
Optical mirrors consist of metallic or dielectric films deposited directly on a substrate such as glass, differing from common mirrors, which are coated on the back surface of the ...
Technical Notes
Diffraction Grating Physics
A diffraction grating is essentially a multi-slit surface. It provides angular dispersion, i.e., the ability to separate wavelengths based on the angle that they emerge from the gr ...
Technical Notes
Optical Coatings
Optical coatings typically consist of thin films made up of single or multiple layers of either metallic or dielectric materials. When properly designed and fabricated, these coatings ...
Technical Notes
Optical Filter Characteristics
In addition to being deposited on the surface of an optical component, optical coatings can also be incorporated into a single element through deposition on one or many substrates followed ...
Technical Notes
Optical Lens Physics
Lenses are essentially light-controlling elements and so are exploited for light gathering and image formation.
Technical Notes
Fiber Optic Physics
This technical note discusses the fundamental physics of optical fibers, their practical implementation, and the various types of optical fibers.

Technical Notes
Laser Diode Production Burn-In
High temperature burn-in screening is used in laser diode manufacturing to screen out devices that are likely to have unacceptably short lives and to ensure that the remaining population ...
Technical Notes
Laser Diode Life Testing
Life test studies are used to collect laser diode lifetime data under carefully controlled operating conditions. These data are then used to develop statistical models that can predict ...
Technical Notes
Laser Diode Characterization
Laser diodes are characterized by their inherent physical properties within five distinct categories, including: electrical, spatial, spectral, optical, and dynamic properties.
Technical Notes
Optical Transceiver Physics
OE converters typically employ photodiodes to absorb incoming photons and convert them into electrical current. Photodiodes are devices in which p-type, n-type, and intrinsic semiconductors ...
