TECHNICAL DESCRIPTION

The invention relates to the field of coupled waveguide arrays and, more specifically, to waveguide arrays comprising several coupled waveguides approximately parallel and oriented in the guiding direction. All the waveguides comprise a first area composed of coupled waveguides according to a first coupling coefficient.
The invention concerns the domain of integrated optics and photonic integrated circuits. A new way to make use of waveguide coupling allows for control, deviation, focusing and routing of optical beams formed in waveguide arrays. The approach gives rise to both passive and active devices, all-optical in principle but possibly controllable by any external parameter.

BENEFITS

Easy and extended control of optical beam direction, divergence and power density near the surface of a dielectric material, where all-optical functionalities can be implemented almost like in free space thanks to simple masking techniques over waveguide arrays.

INDUSTRIAL APPLICATIONS

Guided optics and elecro-optic or all-optical processing of the optical signal.

Simulation of the gaussian beam focussing on around 2 waveguides

Waveguide array heterostructure on InP
