Very Small PLC Chip

Very Small PLC Chip

Our very small PLC chip uses ultra-high index technology for size reduction and volume production. It is applicable to wavelength MUX/DEMUX in transceiver and contributes downsizing of transceiver.

AWG Multi / Demultiplexer

Athermal AWG

AWG (Arrayed Waveguide Grating) is a multi-port optical filter that has a large number of waveguides in an array.

Thermal AWG

NEL is the pioneer and market leader of AWG. NEL's AWG combines and splits optical signals of different wavelengths for use in WDM systems. The heart of the device, the AWG, consists of a number of arrayed channel waveguides that act together like a diffraction grating in a spectrometer.

WDM-PON Athermal AWG

NEL's WDM-PON Athermal AWG covers both C-band and L-band simultaneously by cyclic property. This dual band operation can be used for upstream and downstream of the access network. NEL's patented design technology compensating temperature-dependent wavelength change for wide operating temperature range ( -40 to +70 degree C ).
