Abstract: Optical switch (70) integrated into a substrate, comprising N input channels (74-76) with N input optical free space elements (181-183), a large optical free space element (151), N input tunable optical lenses (152-154) with adjustable projection characteristic for projecting light waves received fro m the input optical free space elements (181-183) into the large free space element (151). The switch further comprises M output channels (190 - 192) wi th M output optical free space elements (77-79), M output tunable optical lense s (155-157) with adjustable receiving characteristic for capturing the light wave from the large free space element (151) and for feeding the light wave to the M output optical free space elements (77-79).

Abstract: An optical adaptor OA monolithically integrates optical elements OE and first micro-mechanical features which define at least a first horizontal reference surface HP and a first vertical reference surface VP, wherein, said first horizontal reference surface HP is perpendicular to an optical plane, the latter being perpendicular the optical axis of said optical elements OF; and said first vertical reference surface VP is perpendicular to said first horizontal reference surface HP and parallel to said optical axis. Alignment of the elements may thereby be achieved. The optical elements may be a lens array and a mirror. The adaptor may be used for connecting to a photonic chip with a waveguide. The adaptor may also have second horizontal and vertical reference surfaces (CVP, CHP, Fig 5c).

Abstract: The invention is notably directed to a scanning probe microscopy cantilever (10), comprising a body (15) and an electromagnetic sensor (20) having a detectable electromagnetic property varying upon deformation of the body. It further concerns a scanning probe microscope, a detection apparatus and a detection method using relying on such a cantilever. The sensor may comprise an optical waveguide and may comprise a closed loop ring resonator or racetrack resonator. The sensor 20 may be a Mach Zehnder interferometer.

Abstract: An optical waveguide device is proposed which comprises a substrate, thereupon a lower cladding layer, thereupon an upper cladding layer and between said cladding layers a waveguide element. The influence of the substrate on the stress-induced birefringence of the optical waveguide device is reduced by modification of the substrate from underneath the waveguide element.
