We investigate integrated narrow-bandwidth interference filters for light in the infrared wavelength region around A=1550 nm fabricated in channel waveguides in lithium niobate. The filters are based on holographically recorded refractive index Bragg gratings, one grating is thermally fixed. The devices ...
Does anyone know the wavelength of IR LEDs needed for the PS3 Guncon 3 IR guns. Regular 940nm IR LEDs that work with the Wii camera for example aren't picked up by the Guncon 3 gun, and the Wii camera doesn't pick up the Guncon 3 LED spots. Are they regular IR LEDs with some ...

The visible spectrum is a visible area of the electromagnetic wave and it is noticeable to the eyes of a human. The range of visible spectrum in the electromagnetic spectrum ranges from the region of IR to the ultraviolet. The detection range of the light spectrum can range from 400 nm to...
PROBLEM TO BE SOLVED: To provide a single crystal of lithium niobate for optical use excellent in polarity control characteristics, nonlinear optical characteristics and electro-optic characteristics, and to provide an optical element using the single crystal, and a manufacturing method for stably growin...
Inwirelesssystems, wavelength is usually specified in meters (m), centimeters (cm) or millimeters (mm). In the case of infrared (IR), visible light, ultraviolet (UV) and gamma radiation (γ), the wavelength is more often specified in nanometers (nm) or angstroms (Å). Nanometers are ...

Coupling of light to and from a microdisk resonator is a crucial step for the integration of this photonic structure in a photonic integrated circuit. However, the most common lateral coupling scheme, based on a point contact with a coplanar bus waveguide, suffers from strong wavelength dependence...
