Tunable AWG multiplexer

In integrated optics the multiplexing and demultiplexing of signals is still a challenge and there is need for integrated elements especially in the field of communication.

Challenge

In integrated optics the multiplexing and demultiplexing of signals is still a challenge and there is need for integrated elements especially in the field of communication.



Technology

The following invention relates to a tuneable integrated arrayed waveguide grating (AWG) device for multiplexing and demultiplexing signals and to a method for tuning said device. The inventive device is an integrated-optics device, which enables a signal made up of a plurality of signals multiplexed by wavelength division to be injected through an input port such as to obtain, a demultiplexed signal with each component exiting via a different output port. The invention especially makes it possible to tune the AWG device by using stationary acoustic waves such that the acoustically excited optical guides are excited by a linear acoustic wave.

 

Commercial Opportunity

The technology is available for in-licensing or joint development.


Developmental Status

The proof of concept has been established.


Patent Situation

A priority claiming Spanish patent application, ES2398113, was filed in 2011, followed by a PCT-application, WO2012152977, in 2012.
