TECHNICAL BACKGROUND
Telecom Components
NEL develop and manufacture the world's finest
photonic semiconductors, lightwave circuits, and a
variety of other devices and modules that are
used in optical telecom networks. (http://www.nelworld.com/)
Opti λ consists of those equipments which meet
the telecom reliability standard.
Waveguide Technology
Our waveguide technology enables the highly efficient
wavelength conversion based on nonlinear optics.
Waveguide fabrication employs the wafer-fusion
techniques which promises the long reliability of the
devices.
Crystal
PPLN Technology
Quasi-phase matching technology and a
damage resistant Zn-doped LN crystal is
used for the device fabrication.
