Capability requirement for optical switches for transmission lines to process arbitrarily polarized light because of the...
fiber laser
A fiber laser is a type of laser in which the active gain medium is an optical fiber doped with rare-earth ions such as...
Kerr effect
The Kerr effect, named after the physicist John Kerr who first observed it in 1875, is a nonlinear optical phenomenon where...
photonic crystals
Photonic crystals are artificial structures or materials designed to manipulate and control the flow of light in a manner...
group index
For a given mode propagating in a medium of refractive index n, the velocity of light in vacuum c, divided by the group...
coherent fiber bundle
A coherent fiber bundle (CFB), also known as a coherent fiber optic bundle, is an assembly of multiple optical fibers...
backscattering coefficient, b
Fraction of light counter propagating collinear with the incident source. Processes considering backscattering are Raman,...

1. The branch of physics that deals with the use of electrical energy to create or manipulate light waves, generally by...
Raman spectroscopy
Raman spectroscopy is a technique used in analytical chemistry and physics to study vibrational, rotational, and other...
magnon
A magnon is a quasiparticle representing a quantized spin wave in a magnetic material. In other words, it is a collective...
material scattering
The total scattering attributable to the intrinsic properties of the materials through which an optical wave is propagating.

A ring dye laser that uses prisms and a saturable absorber within the laser cavity to shape and shorten the pulses...
laser-induced fluorescence
Laser-induced fluorescence (LIF) is a spectroscopic technique that involves using a laser to excite molecules or atoms,...
optically uniaxial crystal
A transparent crystalline substance in which the refractive index of the optic axis (extraordinary axis) is different from...
transponder
A receiver-transmitter device that automatically transmits a signal when the proper interrogating signal is received.
design and engineering consulting services
Design and engineering consulting services refer to professional services provided by specialized firms or individuals to...
cladding mode stripper
A mechanism or device, especially a coating with a refractive index equal to or slightly greater than that of an optical...
optical gate
An optical gate typically refers to a device or system that controls the transmission of light, allowing it to pass through...
electrical length
Expression of the length of a transmission medium in terms of wavelengths of the propagating wavelength. In general,...
normal dispersion
Dispersion characterized by an increasing index of refraction in the medium as the frequency of the propagating light...
probe
Acronym for profile resolution obtained by excitation. In its simplest form, probe involves the overlap of two...
fluorescence correlation spectroscopy
A powerful method, referred to as FCS, for determining the average diffusion coefficients of fluorescent molecules in...
gated pulse
A discontinuous burst of laser light generated by timing or "gating'' a continuous-wave laser.
laser gyroscope
Counter propagating beams imaged along the same path in order to detect rotation. Precise rotation is measured through...
differential mode attenuation
The variation in attenuation among the propagating modes of an optical fiber.
